Cement & Concrete

Cement and Concrete . In its simplest form, concrete is a mixture of paste and aggregates. The paste, composed of portland cement and water, coats the surface of the fine and coarse aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.

High-Strength Concrete

Testing is an integral step in the production process, since quality control studies show that slight changes in mixture proportions can lead to large changes in the compressive strength of concrete. When the design proportioning is complete, mixing can commence with extra consideration for workability and related properties of the mix.


High Density Concrete. High density concrete is a concrete having a density in the range of 6000 to 6400 kg/cu.m. High density concrete is also known as Heavy weight concrete. High density concrete is mainly used for the purpose of radiation shielding, for counterweights and other uses where high density is required. The high density concrete has a better shielding property, so that it can ...


The manufacture of concrete is fairly simple. First, the cement (usually Portland cement) is prepared. Next, the other ingredients—aggregates (such as sand or gravel), admixtures (chemical additives), any necessary fibers, and water—are mixed together with the cement to form concrete. The concrete is then shipped to the work site and placed ...

Ready-Mix Concrete - CEMEX

Standard ready-mix concrete is the most common form of concrete. It is prepared for delivery at a concrete plant instead of mixed on the construction site, which guarantees the quality of the concrete. This type of concrete can provide a structural function, as well as an aesthetic or decorative finish.
