Jun 01, 2016 · The strength of the concrete is related to the composition of sands used in concrete mix. Hence, the content and type of clay, and the percentage of feldspar and mica in the aggregates should always be determined before they are used in the concrete mix. The presence of clay in the natural sand reduces the concrete strength by nearly 10 MPa.
