Cement Calculator
Portland cement is a type of cement in the form of a finely ground powder that consists mainly of lime, silica, and alumina. When mixed with water, it forms a paste that sets and hardens at room temperature. It is called "hydraulic cement" because it hardens when mixed with water, or "grey cement" because of its color.
Aggregates
Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete.
