The invention discloses a fireproof heat-resistant concrete. The concrete is characterized by comprising the following raw materials by weight: 100-400 parts of cement, 125-550 parts of an admixture,100-300 parts of water, 808-1608 parts of an aggregate, 50-200 parts of polyvinyl chloride resin, 75-150 parts of acrylate rubber, 25-75 parts of zinc borate, 40-90 parts of an inorganic flame retardant, and 20-152 parts of a water reducing agent. Compared with the prior art, the concrete has the advantages and effects that: the prepared concrete is long in thermal stabilization time, good in fireproof performance, resistant to high temperature, not prone to cracking and less in slump loss, and the safety performance and economic benefits of building materials are greatly improved. In addition, the preparation method of the concrete is simple, convenient and suitable for large-scale popularization.
本发明公开了一种防火耐热混凝土，其特征在于，包括下列重量份的原料：水泥100‑400份；掺合料125‑550份；水100‑300份；骨料808‑1608份；聚氯乙烯树脂50‑200份；丙烯酸酯橡胶75‑150份；硼酸锌25‑75份；无机阻燃剂40‑90份；减水剂20‑152份；本发明具有以下优点和效果：本发明制备的混凝土热稳定时间长、防火性能好、耐高温、不易开裂，塌落度损失较少，大大提高了建筑材料安全性能和经济效益。此外，该混凝土制备方法简单方便，适合大规模推广。
