Study on the Cemfiber Reinforced High-Performance Concrete

The effects of Cemfiber on the workability, mechanical properties, resistance to chemical corrosion and drying shrinkage of High-Performance Concrete (HPC) have been studied systematically. The results show that: (1) the effects of Cemfiber on the workability of HPC are related to parameter of mix proportion. Generally speaking, Cemfiber does not reduce the workability of HPC; (2) the effect of Cemfiber on the compressive strength and flexural strength is very small; (3) the HPC incorporated with Cemfiber has high resistance to corrosion of hydrochloric acid; (4) Cemfiber may reduce drying shrinkage of HPC significantly; (5) Cemfiber may increase cracking resistance of HPC resulting from drying shrinkage.
