Anti-freezing concrete and preparation method thereof
The invention discloses anti-freezing concrete and a preparation method thereof. The preparation method comprises the steps of 1), mixing bentonite, perlite, a coupling agent, an anti-freezing agent and water for the first time, then conducting ultrasonic concussion to obtain a modified mixture, and mixing the modified mixture and cement for the second time to obtain cement soil; 2) conducting third-time mixing on broken stones, fine aggregate sand and grinding wheel ash to obtain an aggregate mixture; and 3) performing fourth mixing on a composite water reducer, an air entraining agent, an accelerator and a solvent to obtain an additive mixture, and performing fifth mixing on the cement soil, the aggregate mixture and the additive mixture to obtain the anti-freezing concrete. The anti-freezing concrete still has excellent anti-freezing performance on the premise of using less mineral powder and mineral soil.
本发明公开了一种防冻混凝土及其制备方法，该制备方法包括：1)将膨润土、珍珠岩、偶联剂、防冻剂和水进行初次混合，接着进行超声震荡以得到改性混合物，将所述改性混合物、水泥进行第二次混合以得到水泥土；2)将碎石子、细骨料砂子、砂轮灰进行第三次混合，以得到骨料混合物；3)将复合减水剂、引气剂、速凝剂、溶剂进行第四次混合以得到添加剂混合物，将所述水泥土、骨料混合物、添加剂混合物进行第五次混合以得到所述防冻混凝土。该防冻混凝土在使用较少矿粉和矿土的前提下仍然具有优异的防冻性能。
