Research on the Lnfluence of HF-QF Expansion Fiber Cracking Resistance Waterproof Agent on the Splitting and Tensile Properties of Concrete
This article studies the effect of HF-QF expansion fiber anti crack waterproofing agent on the splitting tensile strength of C35 ordinary concrete,and fully analyzes the actual effect of HF-QF expansion fiber anti crack waterproofing agent on improving the splitting tensile performance of concrete through the splitting tensile failure morphology,axial compressive strength,elastic modulus,and stress-strain curve.The experimental results show that HF-QF expansion fiber anti crack waterproofing can improve the splitting tensile strength of C35 ordinary concrete,with an optimal dosage of 30 Kg/m3,An increase of 35.50%compared to the blank sample;The failure mode of concrete mixed with HF-QF expansion fiber crack resistant waterproof agent is central cracking failure accompanied by local compression failure;The stress-strain curve of HF-QF expansive fiber concrete shows its susceptibility to brittle failure.
