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 June 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.
