What is Water Cement Ratio? Its Calculation [Complete Guide

The strength of Concrete / Mortar is dependent on the net quantity of water used per sack of cement.. Cement and water are the only two chemically active elements in concrete. By their combination they form a glue-like binder paste, which surrounds and coats the particles of the inert mineral aggregates, sets and upon hardening binds the entire product into a composite mass.


(sand, cement, lime and admixtures) and then delivered to site, normally in a silo or bags. On site the silo is connected to a power and water supply. When mortar is needed, the silo discharges the dry mortar mix into a screw feed, where it is mixed with the correct amount of water and discharged into
