Abstract

As a new type of modified fiber, model steel fiber has both the appearance and function of steel fiber and the advantages of synthetic fiber. In order to make up for the mechanical properties of rubber concrete, the basic mechanical properties of C30 model steel fiber content reinforced rubber concrete, including compressive strength, splitting tensile strength, flexural strength, and static elastic modulus were studied. The results show that: the rubber particles decrease concrete strength, and the lower rate of compressive strength is greater than the bending and splitting tensile strength, but the toughness of concrete is enhanced. The 6-18mesh with10% vol. was chosen. The model steel fiber changed the damage state of rubber concrete, producing only micro cracks in the compressive, splitting tensile and flexural failure. When the model steel fiber content is 8 kg/m3, 28 d flexural strength increases by 25.8%, the ratio of compressive strength to flexural strength and the static elastic modulus is reduced by 6.9% and 5.3%.
