Light high-strength silicate ceramsite concrete
The invention discloses light high-strength silicate ceramsite concrete. Each cubic meter of the light high-strength silicate ceramsite concrete is composed of the following components: 450 kg of a cementing material, 768-810 kg of coarse aggregate ceramsite, 674-735 kg of fine aggregate river sand, 113-135 kg of water and 4-5 kg of a high-performance water reducing agent, wherein the cementing material comprises 320 to 400 kg of cement, 25 to 98 kg of fly ash and 25 to 38 kg of silica fume, and the water-binder ratio is 0.25 to 0.3. The autoclaved silicate ceramsite is adopted as the coarse aggregate, the concrete with the density smaller than 2,000 kg/m < 3 > and the strength larger than 70 MPa can be prepared, and the light high-strength silicate ceramsite concrete has the advantages ofbeing small in strength discreteness, excellent in performance and the like.
本发明公开了一种轻质高强硅酸盐陶粒混凝土，每立方米组成如下：胶凝材料450kg、粗骨料陶粒768~810kg、细骨料河砂674~735kg、水113~135kg和高性能减水剂4~5kg，其中，胶凝材料包括水泥320~400kg、粉煤灰25~98kg和硅灰25~38kg，水胶比为0.25~0.3。本发明提出采用蒸压硅酸盐陶粒作粗骨料，可制备出密度小于2000kg/m、强度大于70MPa的混凝土，具有强度离散性小，性能优异等优点。
