To increase the pumpability of concrete, any additive that makes the material more workable is beneficial. To increase concrete pumpability, a variety of chemical admixtures have been used, including air-entraining admixture, high-range water-reducing admixture, and finely divided admixture. The properties of the combination determine which kind of chemical admixture to use in concrete and how […]

Steel wire is stretched and anchored on concrete to create prestress in prestressed concrete structures. As a result, the prestressing systems should basically consist of a way to secure the steel to the concrete and a way to stretch the steel. For pre-tensioning and post-tensioning, separate systems are used. Different Types of Prestressing System 1. […]
