摘   要：结合大体积混凝土的特点和技术要求，详细讨论了矿物掺合料各种效应的特征，以及对大体积混凝土性能的影响。在此基础上，提出了矿物掺合料选择的思路。矿物掺合料的掺量应根据结构的散热条件和强度要求来确定。根据这些分析，提出了大体积混凝土应采用晚龄期强度评定的观点。同时，建议大体积混凝土必须加强养护，延长养护时间。

Abstract: The features of the mineral admixtures and their influence on the performance of mass concrete are discussed detailed combined with the characteristic and technical requirements of mass concrete. In the basis, the choosing thought of mineral admixture is put forward. The content of mineral admixture should be determined according to the condition of the dissipation and the requirement on strength of structure. According to the analysis, the viewpoint evaluating mass concrete by the strength at lately age is carried out. Simultaneously, it is considered that the curing of mass concrete must be strengthened and the curing time should be lengthened.
