	DISCONTINUED OPERATIONS
	Through the first quarter of 2014, Tulsa Dynaspan, Inc. (TDI) and Beaver Lake Concrete, Inc. (BLC) were classified as discontinued operations since these companies were no longer producing and selling ready-mixed concrete or issuing construction contracts. TDI’s facilities that were not sold are currently under a lease/purchase agreement and BLC’s ready-mixed facilities have been leased. BLC retained its cement transport trucks and hauls cement for third parties. Prior to discontinuing their ready-mixed concrete operations, BLC transported cement for their own ready-mixed concrete operation but did not haul for other companies. BLC's and TDI's current revenue streams are derived from different operations from those that were discontinued. The current operations of TDI and BLC will continue into the foreseeable future and as a result, their operating results for the second quarter of 2014 and going forward are included in continuing operations and their property, plant and equipment has been reclassified from "Other Assets" to "Property, Plant and Equipment".

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]	'
Nature of Operations and Summary of Significant Accounting Policies	'
	The Monarch Cement Company (Monarch) is principally engaged in the manufacture and sale of portland cement. The marketing area for Monarch's products consists primarily of the State of Kansas, the State of Iowa, southeast Nebraska, western Missouri, northwest Arkansas and northern Oklahoma. Sales are made primarily to contractors, ready-mixed concrete plants, concrete products plants, building materials dealers and governmental agencies. Subsidiaries of Monarch (which together with Monarch are referred to herein as the "Company") sell ready-mixed concrete, concrete products and sundry building materials within Monarch's marketing area.
	For a summary of accounting policies, the reader should refer to Note 1 of the consolidated financial statements included in our Company's most recent annual report on Form 10-K.
	Certain amounts in the prior periods presented have been reclassified to conform to the current period financial statement presentation. These reclassifications have no effect on previously reported net income.
	Recently Adopted Accounting Standards
	In July 2013, the FASB issued ASU No. 2013-11, "Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss or a Tax Credit Carryforward Exists". With certain exceptions, ASU 2013-11 requires entities to present an unrecognized tax benefit, or portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward. The guidance is effective for interim and annual periods beginning after December 15, 2013 on either a prospective or retrospective basis with early adoption permitted. The guidance became effective for the Company beginning January 1, 2014 and did not have a material impact on its consolidated results of operations and financial condition.
	New Accounting Standards Issued But Not Yet Adopted
	In April 2014, the FASB issued ASU No. 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity". ASU 2014-08 provides guidance for determining which disposals can be presented as discontinued operations and modifies related disclosure requirements. The guidance defines a discontinued operation as a disposal of a component or group of components that is disposed of or is classified as held for sale and represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results. This guidance is effective January 1, 2015. We do not expect the adoption to have a material impact on our financial statements.
	In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)" . ASU 2014-09 provides a single, comprehensive revenue recognition model for all contracts with customers. Under the new guidance, an entity will recognize revenue to depict the transfer of promised goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. A five step model has been introduced for an entity to apply when recognizing revenue. The new guidance also includes enhanced disclosure requirements, and is effective January 1, 2017. Entities have the option to apply the new guidance under a retrospective approach to each prior reporting period presented, or a modified retrospective approach with the cumulative effect of initially applying the new guidance recognized at the date of initial application within the Consolidated Statement of Changes in Stockholders' Equity. We are in the process of evaluating the application and implementation of the new guidance.

Accounts Receivable Additional Disclosures [Abstract]	'
Receivables	'
	Our Company groups its operations into two lines of business - Cement Business and Ready-Mixed Concrete Business. The "Cement Business" refers to our manufacture and sale of cement and "Ready-Mixed Concrete Business" refers to our ready-mixed concrete, concrete products, and sundry building materials business. Our Ready-Mixed Concrete Business previously included the concrete construction division of TDI which involved short-term and long-term contracts. The operations of TDI were discontinued in 2013 due to consecutive year operating losses. See Note 2, "Discontinued Operations", for further discussion. Short-term contracts for specific projects were generally of three to six months in duration. Long-term contracts relate to specific projects with terms in excess of one year from the contract date. Revenues from contracts using the cost-to-cost measures of completion were recognized based on the ratio of contract costs incurred to date to total estimated contract costs. Full provision was made for any anticipated losses. The majority of the long-term contracts would allow only scheduled billings and contained retainage provisions under which 5% to 10% of the contract invoicing may be withheld by the customer pending project completion. As of September 30, 2014, the amount of billed retainage which is included in accounts receivable was approximately $171,200, all of which is expected to be collected within one year. The amount of billed retainage which was included in accounts receivable at December 31, 2013 was approximately $182,500.

	We did not incur a temporary last-in, first-out (LIFO) liquidation gain during the three months and nine months ended September 30, 2014. During the three months and the nine months ended September 30, 2013, we incurred a $0.8 million temporary LIFO liquidation gain due to reductions in finished cement and work in process inventory, of which $0.6 million was restored by the end of 2013. The temporary LIFO liquidation gain has been deferred as a component of accrued liabilities.

Fair Value Disclosures [Abstract]	'
Fair Value	'
	Realized gains (losses) on equity investments are computed using the specific identification method. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements must maximize the use of observable inputs and minimize the use of unobservable inputs. There is a hierarchy of three levels of inputs that may be used to measure fair value:
	Level 1 - quoted prices in active markets for identical assets or liabilities.
	Level 2 - observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
	Level 3 - unobservable inputs supported by little or no market activity and are significant to the fair value of the assets or liabilities.
	Cash and cash equivalents have carrying values that approximate fair value using Level 1 prices. Receivables, accounts payable, and short and long-term debt have carrying values that approximate fair values using Level 2 inputs. Equity securities for which the Company has no immediate plan to sell but that may be sold in the future are classified as available for sale.  If the fair value of the equity security is readily determinable, it is carried at fair value and unrealized gains and losses are recorded, net of related income tax effects, in stockholders' equity. Realized gains and losses, based on the specifically identified cost of the security, are included in net income (loss). The Company's valuation techniques used to measure the fair value of its marketable equity securities were derived from quoted prices in active markets for identical assets (Level 1 prices). Equity securities whose fair value is not readily determinable are carried at cost unless the Company is aware of significant adverse effects which have impaired the investments. Investments that are recorded at cost are evaluated quarterly for events that may adversely impact their carrying value.
	The aggregate amount of equity securities carried at cost, for which the Company has not elected the fair value option, was $0.6 million as of September 30, 2014. The remaining $28.8 million in equity security investments are stated at fair value. As of December 31, 2013, the aggregate amount of equity securities carried at cost was $0.5 million and the remaining $24.8 million in equity security investments were stated at fair value. The following table presents the fair value of the Company's available-for-sale equity securities recognized in the accompanying balance sheets measured at fair value on a recurring basis and the level within the fair value hierarchy in which the fair value measurements fall at September 30, 2014 and December 31, 2013:

	There were no transfers between levels and there were no significant changes in the valuation techniques during the period ended September 30, 2014. No reconciliation (roll forward) of the beginning and ending balances for Level 3 is presented since the Company does not have any assets or liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) at either of the dates reported in the table above.  The Company has no liabilities at either date requiring remeasurement to fair value on a recurring basis in the balance sheet. The Company has no additional assets or liabilities at either date requiring remeasurement to fair value on a non-recurring basis in the balance sheet.

	INVESTMENTS
	Cost Method Investments
	The Company owns stock in a privately-owned company in the ethanol production industry. The investment, for which fair value approximates carrying value, was evaluated at September 30, 2014 and December 31, 2013 for impairment. The evaluations of the investment for each period's impairment analysis were based on the specific identification of shares held and quoted prices in markets that are not active (Level 2) and no impairments were identified. As a result of the evaluations, the Company does not consider the cost-method investment to be impaired at September 30, 2014 or December 31, 2013.
	Fair Value Investments
	Impairment Analysis
	September 30, 2014--The Company's investments in available-for sale securities carried at fair value were evaluated for impairment by comparing the specifically identified cost of each investment to market price. As a result of these evaluations, the Company did not identify any other-than-temporary impairments in investments which would have resulted in a recognized loss in earnings of equity investments. The Company did identify some specific investments in available-for-sale equity securities that were not other-than-temporarily impaired resulting in the recognition of unrealized losses (see table above in Note 7 "Fair Value"). These unrealized losses relate to investments in the common stock of one company in the residential construction industry. When the Company evaluated the impairment by comparing the specifically identified cost of each investment to market price as of October 21, 2014, the residential construction industry securities' price per share increased from September 30, 2014 levels which reduced temporary impairments by $51,000 or 51.2%. The Company evaluated the near-term prospects in relation to the severity of the impairments and the duration of the impairments. Based on that evaluation, the Company does not consider these investments to be other-than-temporarily impaired at September 30, 2014.
	December 31, 2013--The Company's investments in available-for sale securities carried at fair value were evaluated every quarter for impairment by comparing the specifically identified cost of each investment to market price. As a result of these evaluations, the Company did not identify any other-than-temporary impairments in investments which would have resulted in a recognized loss in earnings of equity investments. The Company did identify some specific investments in available-for-sale equity securities that were not other-than-temporarily impaired resulting in the recognition of unrealized losses (see table above in Note 7 "Fair Value"). These unrealized losses relate to investments in the common stock of one company in the residential construction industry. When the Company evaluated the impairment by comparing the specifically identified cost of each investment to market price as of February 3, 2014, the residential construction industry securities' price per share decreased slightly from December 31, 2013 levels. The Company evaluated the near-term prospects in relation to the severity of the impairments and the duration of the impairments. Based on that evaluation, the Company did not consider these investments to be other-than-temporarily impaired at December 31, 2013.

	Equity Method Investments
	The Company owns common stock of GFI, a privately-owned company in the brick industry. During 2013, the Company purchased $0.7 million in additional shares of GFI resulting in a 19.34% ownership as of December 31, 2013. Previously, the Company accounted for the investment as a cost method investment as management believed it did not have significant influence over GFI. As a result of the additional investment, the Company has determined that it has the ability to exercise significant influence, but not control, over the operating and financial policies of GFI. Consequently, the equity method of accounting is used for the investment and prior period financials from 2001 forward have been adjusted to reflect the change in accounting. In May and August 2014, the Company purchased a total of $0.5 million GFI stock resulting in a 22.77% ownership as of September 30, 2014.
	The following financial statement line items for September 30, 2013 were affected by the change in accounting principle from cost method to equity method of accounting for the investment in GFI:
			For the Three Months Ended							For the Nine Months Ended
	30-Sep-13		As Adjusted				As Previously Reported			As Adjusted			As Previously Reported

	Equity in earnings		$	52,489			$	(3,022	)	$	58,327		$	(15,275	)
	* The difference between carrying amount and the underlying equity in net assets is in a memo account allocated to goodwill.
	During the three months ended September 30, 2014 and 2013, the Company purchased $0.2 million and $0.2 million, respectively, of brick from GFI in arm's length transactions in the normal course of business for resale to third parties. During the nine months ended September 30, 2014 and 2013, the Company purchased $0.7 million and $0.6 million, respectively, of brick from GFI in arm's length transactions in the normal course of business for resale to third parties. The Company eliminated intra-entity profits or losses for its proportionate share of GFI's common stock for inventory still remaining with the Company until such profits or losses were realized in transactions with third parties. Amounts due to GFI for Company purchases were not significant at September 30, 2014 and September 30, 2013.
	The Company's equity method investment is reviewed for impairment on a periodic basis or if an event occurs or circumstances change that indicate the carrying amount may be impaired. This assessment is based on a review of the investment's performance and a review of indicators of impairment to determine if there is evidence of a loss in value of the investment. Factors the Company considers include:
	•	Absence of the Company's ability to recover the carrying amount;
	•	Inability of the equity affiliate to sustain an earnings capacity which would justify the carrying amount of the investment; and
	•	Significant litigation, bankruptcy or other events that could impact recoverability.
	For an equity investment with impairment indicators, the Company measures fair value on the basis of discounted cash flows or other appropriate valuation methods (Level 3). If it is probable that the Company will not recover the carrying amount of its investment, the impairment is considered other-than-temporary and recorded in earnings, and the equity investment balance is reduced to its fair value accordingly. After review, the Company does not consider its equity method investment, for which fair value approximates carrying value, to be impaired at September 30, 2014 or December 31, 2013.
