Inventory Disclosure [Abstract]
Inventories	INVENTORIES 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.

The entire disclosure for inventory. This may include, but is not limited to, the basis of stating inventory, the method of determining inventory cost, the major classes of inventory, and the nature of the cost elements included in inventory. If inventory is stated above cost, accrued net losses on firm purchase commitments for inventory and losses resulting from valuing inventory at the lower-of-cost-or-market may also be included. For LIFO inventory, may disclose the amount and basis for determining the excess of replacement or current cost over stated LIFO value and the effects of a LIFO quantities liquidation that impacts net income.
