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.
