Experimental Study on Basic Mechanical Properties of Polypropylene Fiber-Reinforced Ceramsite Concrete
In order to improve the strength and brittleness of ceramsite concrete,polypropylene fiber was added to ceramsite concrete in this study.A total of 180 polypropylene fiber-reinforced ceramsite concrete specimens were prepared,and cube compressive test,splitting tensile test,axial compressive test and elastic modulus test were carried out.The results show that polypropylene fiber can effectively improve the splitting tensile strength and tension-compression ratio of ceramsite concrete,and has little effect on compressive strength and elastic modulus.Based on the experimental results,the conversion relationship model between splitting tensile strength and cube compressive strength,axial compressive strength and cube compressive strength,and the numerical model of elastic modulus of polypropylene fiber-reinforced ceramsite concrete were proposed.
