Ultra-high performance concrete containing volcanic rock powder as well as preparation method and application of ultra-high performance concrete
The invention relates to ultra-high performance concrete containing volcanic rock powder as well as a preparation method and application of the ultra-high performance concrete. The ultra-high performance concrete comprises the following components in parts by weight: 700-750 parts of cement, 40-50 parts of silica fume, 500-550 parts of volcanic rock powder, 1800-2000 parts of machine-made sand, 25-35 parts of a water reducing agent and 195-205 parts of water, the volcanic rock powder has the specific surface area of not less than 500m < 2 >/kg and the ignition loss of not more than 1.5%. Compared with the prior art, the ultra-high performance concrete disclosed by the invention not only can enhance the compressive strength of the ultra-high performance concrete, but also can effectively reduce the drying shrinkage of the ultra-high performance concrete.
本发明涉及一种含有火山岩粉的超高性能混凝土及其制备方法与应用，所述超高性能混凝土包括以下重量份组分：水泥700～750份，硅灰40～50份，火山岩粉500～550份，机制砂1800～2000份，减水剂25～35份，水195～205份；所述火山岩粉的比表面积≥500m2/kg，烧失量≤1.5％。与现有技术相比，本发明的超高性能混凝土不仅能增强超高性能混凝土的抗压强度，还可有效降低超高性能混凝土的干燥收缩。
