How to Calculate the Swell Factor of Soil | eHow

2021-9-21 · Building on a soil with a large swell factor can be costly. Soils with a high percentage of swelling clay can be difficult to grow plants in because water may pool on the surface. Calculating the swell factor of soil depends on the amount of water it can hold. The swell factor of some soils can be high and create enough force to break concrete.

Recycled Concrete Aggregate

Recycled concrete aggregate (RCA) is the designation used in BS 8500-2 for recycled aggregate principally comprising crushed concrete. Designations of recycled aggregate other than RCA are of lower quality and may contain significant quantities of masonry which would preclude or limit their use in structural concrete.
