fis-2467	Qiu, Peng	Experimental Research on Fracture Behavior of Concrete after High Temperature	2019	10	.pdf	application/pdf	5523	306	54	Based on the double K fracture model, the fracture properties of C70 strength grade concrete after being processed by high temperature of 25 °C ~ 800 °C were studied by three-point bending beam test. The change rules of fracture toughness KIC and fracture energy under different temperatures after being processed by high temperature were analyzed.	cache/fis-2467.pdf	txt/fis-2467.txt
