The Differences Between Cement, Concrete, and Mortar

 · The Spruce / Liz Moskowitz. Concrete . Concrete is a complete building material used for foundation walls, concrete slabs, patios, and many other masonry structures. It is uniquely versatile because it starts out as a simple, dry mixture, then becomes a flexible, semi-liquid material capable of forming into any mold or shape, and which dries into the hard-as-rock material we know as concrete.

Cement clinker

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

Decarbonizing Steel and Cement

The heat used for this process is an emissions problem on its own, but more than 60 percent of the annual emissions from cement production comes from the limestone itself. This also means that, like steel, methods to improve the efficiency of the cement-making process are limited in their CO 2 reduction potential.

Cracked Concrete

 · Concrete slabs can shrink as much as 1/2 inch per 100 feet. This shrinkage causes forces in the concrete which literally pull the slab apart. Cracks are the end result of these forces. The bottom line is a low water to cement ratio is the number one issue effecting concrete quality- and excess water reduces this ratio.
