Coral concrete is more prone to brittle fracture than traditional concrete under external load due to its porous and brittle properties.In order to effectively inhibit the formation of structural cracks,it is necessary to introduce fiber composite materials to enhance its basic physical properties.The study analyzes the effects of carbon fiber(CF)and copper-coated steel fiber(DTGF)on the basic physical properties of coral concrete.The results show that fiber material can significantly improve the early strength of coral concrete,because the fiber can restrain the lateral expansion of aggregate.The addition of fiber also has positive effect on the splitting strength and elastic modulus of coral concrete.
