Cement / Concrete

Fresh Concrete

In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of Portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Rice husk ash is one of the promising pozzolanic materials that can be blended with Portland cement for the production of durable concrete. . Rice husk ash mixed in Portland cement not only improves the early strength of concrete, but also forms a calcium silicate hydrate (CSH) gel around the cement particles which is highly dense and less porous.
