An accumulation of cement and concrete statistics helps to define how quarterly predictions of the National Ready Mixed Concrete Association are divided among residential, nonresidential, and public works. After determining the dollar value of concrete, the authors then compared the total concrete dollar value with U.S. Census Bureau figures for annual total value of construction for each market segment.

The authors estimate the concrete has a nearly $80 billion (in-place) cost for 1999. Of the three-residential, nonresidential, and public works-public construction is the largest, followed by residential buildings. The trendline for concrete usage is upward through 2002, which bodes well for the concrete industry.

The article includes tables revealing ready-mixed concrete use by market segment, portland cement consumption, and total annual dollar value of in-place concrete.
