Experimental Study on Mechanical Properties of Hybrid Fiber High-Strength Concrete

Abstract:

Design 6 different dosages of C70 hybrid fiber high-strength concrete and a group of ordinary-strength concrete C70. By test of compressive strength and splitting tensile strength, discovery the high-strength hybrid fiber concrete compressive strength is not increasing trend; tensile strength increases significantly, average up to 5.12MPa, tension and compression ratio increased by 12%~40%; specimens eventually destroying the near ductility failure, in the case of 1.2% volume dosage of steel fiber and 0.10% volume dosage of polypropylene fiber, tension and compression ratio reach to 0.0683, hybrid fiber high-strength concrete showed good mixing effect, in the large-scale concrete construction has a certain spread value.
