Introduction to Concrete - Portland Cement Association

68.4 million metric tons, or 75.2 million tons, of cement were consumed in the United States in 2009. Nearly two-thirds of cement consumption occurs between May and October, closely correlating with the construction season. The majority of cement is shipped to ready mixed concrete producers which accounts for 72% of cement consumption.

Concrete Technology - Portland Cement Association

Concrete Technology. In its simplest form, concrete is a mixture of paste and aggregates (rocks). The paste, composed essentially of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a series of chemical reactions called hydration, the paste hardens and gains strength to form the rock-like ...

GGBS Concrete - The Cementitious Slag Makers Association

The rate of reaction and strength development of GGBS concrete is slower than equivalent concrete made with Portland cement CEM I but continues at a significant rate for much longer (data indicates continued development after many years). Typically the 7-day strength of a ggbs concrete will be 55-65% of the 28-day strength compared to 70-80% for a similar CEM I Portland cement concrete.
