Research on Strength Optimization Design of High Performance Concrete with Superfine Glass Bead

超细玻璃微珠作为改善高性能混凝土的矿物掺合料,对高性能混凝土强度的改善程度还有待进一步研究。本文通过试验研究了微珠和硅灰复掺以及水胶比对强度的影响;并应用价值工程理论,对玻璃微珠高性能混凝土强度进行优化设计分析,根据功能指数和成本指数确定价值指数,从而确定经济合理的强度设计方案,并应用极差分析了两种因素对强度的影响情况。

As the mineral admixture of high performance concrete, the improvement of the superfine glass bead on the strength of high performance concrete needs to be further studied. The effects of the mixing ratio of beads and silica fume on the strength of water binder ratio are studied. By the application of value engineering theory, the glass bead strength of high performance concrete analysis and design optimization are carried out. According to the functional index and the cost index, the value index is confirmed to determine the strength of economical and reasonable design scheme, and the influence of these two factors on the strength is analyzed by the range analysis.
