Cement Concrete: Advantages and Disadvantages

2017/12/12ADVERTISEMENTS: Cement concrete is an important construction material. Its importance is increasing every day. It is a composite material consisting of a binding material, which is essentially cement, inert mineral Filler, known as aggregates and water. Thus cement concrete can be prepared by mixing above ingredients in a fixed proportion. Green concrete is a plastic []

Explained: Cement vs. concrete — their differences, and

2020/04/03What makes concrete so strong is the chemical reaction that occurs when cement and water mix — a process known as hydration. "Hydration occurs when cement and water react," says Ulm. "During hydration, the clinker dissolves into the calcium and recombines with water and silica to form calcium silica hydrates."

Cement Concrete

The Portland cement concrete mixture contains 340 kg cement/m 3, which is 20 kg above the minimum cement content for freeze-thaw-resistant concrete (XF2-XF4) according to DIN EN 206-1/DIN 1045-2. The already optimised geopolymer concrete ( Dombrowski et al ., 2008) with a slag/fly ash ratio of approximately 80:20 does not need any heat curing and hardens at room temperature (20C).

Yorkshire Water tests new concrete surface technology in

2021/01/20It says that the alumina and zirconia silicate ceramic surface treatment protects concrete from wet/dry and freeze/thaw cycles, peeling, flaking, chalking and delaminating. This reduces the need for replacement of concrete structures, reducing CO 2 intensity by 43% compared to bare concrete, according to the company.
