High-temperature-resistant concrete with good workability and preparation method thereof
The invention belongs to the technical field of concrete, and discloses high-temperature-resistant concrete with good workability and a preparation method thereof. The concrete is prepared from the following raw material components in parts by weight: 210 to 230 parts of water, 359 to 471 parts of cement, 77 to 181 parts of granulated blast furnace slag, 800 to 830 parts of granite macadam, 780 to 820 parts of natural river sand and 0.7 to 0.8 part of polycarboxylic acid type water reducing agent. According to the invention, a proper amount of granulated blast furnace slag is added into a concrete formula to be matched with other components, so that not only can the use amount of cement be reduced, but also the workability and high temperature resistance of the concrete can be effectively improved.
本发明属于混凝土技术领域，公开了一种耐高温且和易性好的混凝土及其制备方法。该混凝土中包括以下重量份数的原料组分：水210‑230份、水泥359‑471份、粒化高炉矿渣77‑181份、花岗岩碎石800‑830份、天然河砂780‑820份、聚羧酸型减水剂0.7‑0.8份。本发明通过在混凝土配方中加入合适量的粒化高炉矿渣与其余组分进行配合，不仅可以减少水泥的用量，还能有效提高混凝土的和易性和耐高温性能。
