Study on the Effect of Cellulose Fiber on the Crack Resistance of High Performance Concrete

Abstract

Combining the South-to-North Water Diversion Middle Route Project, the effect of cellulose fiber on the mechanical property, ultimate tensile value, compressive elasticity modulus, durability and crack resistance property of high performance concrete was studied. The test results show that mixing with the cellulose fiber in concrete has less effect on the compressive strength, but can improve the splitting tensile strength, the axial tensile strength and ultimate tensile value of concrete, extend the cracking time of concrete, reduce the crack width and the cracking area of concrete and improve the crack resistance of concrete.
