High-stone low-sand concrete and preparation method thereof
The invention relates to the technical field of building materials, and provides high-stone low-sand concrete and a preparation method thereof.The high-stone low-sand concrete is prepared from, by weight, 40-60 parts of limestone, 40-60 parts of granite, 30-50 parts of glow, 20-30 parts of fly ash, 40-60 parts of cement, 10-20 parts of gelling agent, 5-10 parts of nano boron nitride, 2-4 parts of water reducing agent and 2-4 parts of antifreezing agent; the gelling agent is formed by mixing silica sol, tungsten disulfide and calcium sulfate according to the mass ratio of (5-10): 3: 2. By means of the technical scheme, the problem that in the prior art, the strength of high-stone low-sand concrete is low is solved.
本发明涉及建筑材料技术领域，提出了一种高石低砂混凝土及其制备方法，原料包括以下重量份的组分：石灰岩40‑60份、花岗岩40‑60份、辉长岩30‑50份、粉煤灰20‑30份、水泥40‑60份、胶凝剂10‑20份、纳米氮化硼5‑10份、减水剂2‑4份、防冻剂2‑4份；胶凝剂由质量比为5‑10:3:2的硅溶胶、二硫化钨和硫酸钙混合而成。通过上述技术方案，解决了现有技术中的高石低砂混凝土的强度较低的问题。
