Abstract：Coral sand has irregular shape,more porous,flat,powder particles,bibulous rate is bigger,is not conducive to the preparation of the mass concrete,through a reasonable adjustment of sand ratio,water/cement ratio,increase the dosage of admix-ture,mixed with a certain amount of admixture,can make mass concrete which satisfy the requirement of engineering;Through the optimization of mixture ratio design,optimal mixture ratio of mass concrete are as follows:cement:coral sand:gravel:fly ash:corrosion resistant agent:sea freshwater:water reducing agent=337:654:1066:63:20:210:8.4. Through the casting of the test section to verify its construction performance,no visible cracks were found during the observation after more than three months,indicating that the vol-ume stability of the coral sand mass concrete structure is good.
