Mechanical Properties and Energy-saving Effect of Polypropylene Fiber Foam Concrete

摘要

Compared with ordinary concrete, foam concrete possesses advantages such as lightweight, heat insulation, etc., but the internal bubbles have of great influence on its strength. This study examined the impact of polypropylene fibers on mechanical properties of foam concrete using flexural deformation control method and obtained complete load-deformation curve. The results show that, polypropylene fibers significantly affect the compressive property of the foam concrete and improve the carrying capacity after the peak compression load, but have little effect on the compressive strength; polypropylene fibers improve the flexural performance significantly.
