Technical Features and Countermeasures of High Strength and High Performance Concrete

Abstract:

In this paper, the technical problems are discussed, and a couple of countermeasures are proposed. To solve the problems of HPC, such as autogenous-shrinkage caused cracking, cracking caused by swelling, and high plastic viscosity, the key parameters are water content and cement content in mix proportion. Coarse aggregate should comprise of two grades. Such HPC can inhibit autogenous-shrinkage caused cracking, cracking caused by swelling, and lower plastic viscosity and improve pumping performance. Incorporate polypropylene fiber can prevent explosive spalling under high temperature.
