Cement and Concrete
Cement & Concrete. In its simplest form, concrete is a mixture of paste and aggregates. The paste, composed of portland cement and water, coats the surface of the fine and coarse aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.

Cement-Specific Materials
A mixture of soil, portland or blended cement, and water. When first mixed, SC looks like native soil, and it is then placed and compacted in lifts using typical earthmoving equipment. However, the cement acts as a binder between the soil particles and, like cement-treated base (CTB), the SC gains strength and durability as the cement hydrates.

Introduction to Concrete
The maximum size of coarse aggregate is typically 19 mm or 25 mm (3/4 in. or 1 in.). An intermediate-sized aggregate, around 9.5 mm (3/8 in.), is sometimes added to improve the overall aggregate gradation. Since aggregates make up about 60% to 75% of the total volume of concrete, their selection is important.
