摘要
厦门新体育中心巨拱基础属于大体积混凝土,对混凝土的温升控制和工作性要求高。试验通过比对矿物掺合料替代20%、30%、40%、50%的水泥,研究混凝土工作性、强度和绝热温升等性能的变化,优选适宜的矿物掺合料掺量;同时探讨了合理的控制温升措施。
The giant arch foundation of Xiamen new sports center belongs to mass concrete,which has high requirements for temperature rise control and workability of concrete.This test made a comparative study of mineral admixtures substituting 20%,30%,40%,and 50% of cement and evaluated the resultant changes in concrete workability,strength and adiabatic temperature rise in order to optimize the mineral admixture content.Reasonable measures to control the temperature rise have also been discussed.
