Effect of Admixtures on the Mechanical Properties and Durability of Coral Concrete
In order to explore the influence of admixtures on the comprehensive performance of coral concrete,fly ash and silica fume were used to partially replace cement,and C30 and C50 coral concrete were tested.The mechanical properties and durability of coral concrete were tested,and the test results and influencing laws were analyzed.The research results show that the addition of fly ash and silica fume to coral concrete can significantly improve its com-pressive strength,splitting tensile strength,sulfate erosion resistance and Cl-permeability resistance.The best effect is achieved when the addition ratio of both materials is 10％.
