High Performance Concrete Topic

Jul 01, 2021  High-performance concrete (HPC) is concrete that has been designed to be more durable and, if necessary, stronger than conventional concrete. HPC mixtures are composed of essentially the same materials as conventional concrete mixtures, but the proportions are designed, or engineered, to provide the strength and durability needed for the structural and environmental

Spin casting is an effective method to produce concrete pylons, masts or pipes. Through the centrifugation process the concrete is compacted and the desired shape, mostly round or ellipsoidal, is obtained. The pre-cast elements made using conventional concrete generally have to be reinforced with steel bars which are susceptible to corrosion. Furthermore, the placement of the steel ...
