Anti-freezing concrete using solid anti-freezing agent and preparation method of anti-freezing concrete
The invention discloses anti-freezing concrete using a solid anti-freezing agent and a preparation method of the anti-freezing concrete. The solid anti-freezing agent (with a doping amount being 2-8% of the volume of the concrete) is used for replacing an air entraining agent for the anti-freezing concrete, and meanwhile, a defoaming agent is added to enable the air content of the concrete to be smaller than or equal to 1%; and the compressive strength of the obtained pre-mixed anti-freezing concrete is larger than or equal to C40, and an anti-freezing durability index is greater than or equal to DF100. By adding the solid anti-freezing agent, the problems that air content stability of traditional anti-freezing concrete is poor and an anti-freezing performance index is not easy to reach the standard are solved.
本发明公开了一种使用固体防冻剂的抗冻混凝土及其制备方法，该抗冻混凝土由固体防冻剂(掺量为混凝土体积的2％～8％)代替引气剂用于抗冻混凝土，同时加入消泡剂使混凝土的含气量≤1％，所得预拌抗冻混凝土抗压强度≥C40，抗冻的耐久性指数≥DF100。固体防冻剂的加入解决了传统抗冻混凝土含气量稳定性差、抗冻性能指标不易达标的问题。
