Why Is Concrete Better? - Concrete Sask - SRMCA
Versatile, long-lasting and durable, concrete is a cost-effective, sustainable choice for both residential and commercial buildings. Durable. When it's built with concrete, it's built to last. Concrete is a building material that gains strength over time. Concrete's 100-year service life conserves resources by reducing the need for reconstruction.
Concrete without Cement - A Green Alternative Fly Ash
Cement has excellent binding property but its production requires large amount of energy which contributes for pollution and global warming. The process of cement production starts from mining for raw materials, crushing, blending and heating these materials at high temperature of 1500 0 C and finally creating cement from heated materials.
Cement | Industrial Efficiency Technology & Measures
Globally, the cement sector is dominated by a small number of large companies. Largest cement companies, and their capacities and sales are also provided below. Cement production is an energy intensive process, with energy costs representing 20-40% of production costs (IEA, 2007. p. 145).
