Inventory Disclosure [Abstract]
Inventories	INVENTORIES For the three months ended March 31, 2014, we incurred a temporary last-in, first-out (LIFO) liquidation gain due to reductions in finished cement and work in process inventory of $0.5 million which we expect to be restored by the end of the year. The temporary LIFO liquidation gain has been deferred as a component of accrued liabilities. We did not incur a temporary LIFO liquidation gain during the three months ended March 31, 2013.

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.
