ENCYCLOPEDIA OF BUILDING CONSTRUCTION

A concrete admixture is a chemical that you add to concrete while it is being mixed in order to change the properties of the concrete. Some of the most common admixtures are retarders, chemicals that slow the process of setting of concrete, so that it can be mixed in a concrete plant, and then shipped to the site several hours away in a concrete mixer that rotates the concrete to keep it from

Reinforced Concrete | Encyclopedia.com

May 21, 2018 · reinforced concrete. Concrete once set will take a superimposed load that compresses it, but, if used, say, as a beam, will fail if heavily loaded, because it is weak in tension. Steel, on the other hand, is strong in tension, so the two materials are combined to enable the concrete to perform well in tension as well as in compression by casting steel rods in the positions where reinforcing is

Cement IndustryIntroductionCement is a rocky powder that can be mixed with water and molded to any desired shape, after which it hardens to a rock-like consistency. It is used worldwide both as a mortar to join bricks and blocks together and as an ingredient of concrete, which is mixture of crushed rock, sand, and cement that is used to construct buildings, bridges, roads, pipes, dams, and

Concrete - Wikipedia

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past, lime based cement binders, such as lime putty, were often used but sometimes with other hydraulic cements, (water resistant) such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (named for
