Fly ash bricks are hi-tech well-improved quality bricks used for construction of brick masonry structures. They are used as replacement for normal clay bricks and has better properties than it. Fly ash bricks competitive in comparison to the conventional clay bricks
2 Durability. Concrete''s long life means that is more likely that a concrete building will come to the end of its life because no further use can be found for it, rather than a case of the concrete having failed due to age. In these cases, demolition is not always the automatic course. Structures can often be stripped back to their concrete ...
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 ...
Pervious concrete pavement is a unique and effective means to address important environmental issues and support green, sustainable growth. By capturing stormwater and allowing it to seep into the ground, porous concrete is instrumental in recharging groundwater, reducing stormwater runoff, and meeting U.S. Environmental Protection Agency (EPA) stormwater regulations.
