Mass Concrete Design and Construction in Engineering

通过某医疗加速器机房工程大体积混凝土结构设计、施工,介绍了采用低强度等级的内掺微膨胀剂的补偿收缩混凝土,优化混凝土配合比设计,控制原材料的质量,选择低水化热的矿渣硅酸盐水泥,降低入模温度,加强隔热、保温和养护措施,实现了控制大体积混凝土裂缝的产生。

Through the design and construction of mass concrete in a medical aecelerator room, this article introduces the adoption of the low strength expanding-agent-added shrinkage-compensating concrete,the optimization of the mix proportion of concrete, the controlling of the raw material quality, the choice of the Portland-slag cement that has low hydration heal, the reducing of the entering temperature of concrete, into the formwork and the strengthening of heal insulation, humidity maintenance and curing for concrete. And after the adoption of the measures mentioned above, the occurrence of crack in mass concrete is controlled.
