Impact Resistance of Polypropylene Fibre
15/12/2021Concrete with up to 40% CS and 0.6% PPF volume shows a 111.72% increase in the number of blows for failure as compared to the control specimen. The impact resistance at failure was predicted by regression analysis, and very high regression coefficients of 0.93, 0.98 and 0.98 were obtained respectively at 7-, 14- and 28-days curing.

Cement Manufacturing Process: How the Cement is Made?
All the cement plants set up after 1980 use the dry process for the manufacture of cement. In this process, the calcareous materials such as limestone are crushed and stored in silos or storage tanks. The argillaceous material such as clay is thoroughly mixed with water in a container known as the wash mill. This washed clay is stored in basins.

09-05-2012To produce cement, limestone and other clay-like materials are heated in a kiln at 1400C and then ground to form a lumpy, solid substance called clinker; clinker is then combined with gypsum to form cement. Cement manufacturing is highly energy- and emissions-intensive because of the extreme heat required to produce it.

Concrete as a high-tech building material is based on an optimal mixture of sand, aggregates, water and cement. The ratio of water and cement defines the final quality and stability/firmness of the concrete. In addition, the fluctuating moisture of sand must be taken into account, which makes a significant contribution to the overall water content.
