Solid anti-freezing agent for anti-freezing concrete and preparation method of solid anti-freezing agent
The invention discloses a solid anti-freezing agent for anti-freezing concrete and a preparation method of the solid anti-freezing agent, the solid anti-freezing agent is composed of recycled aerated concrete aggregate with single-particle grading or continuous grading in the particle size range of 0.075-1.18 mm, and the solid anti-freezing agent is subjected to modification treatment. The solid anti-freezing agent exists in the anti-freezing concrete in the form of micro aggregate instead of traditional micro bubbles, the anti-freezing durability index of the anti-freezing concrete is improved, efficient utilization of solid waste is achieved, the problem that the gas content of traditional anti-freezing concrete is not easy to control is solved, and the production quality is effectively guaranteed.
本发明公开了一种抗冻混凝土用固体防冻剂及其制备方法，固体防冻剂由粒径为0.075mm～1.18mm范围内单粒级配或连续级配的再生加气混凝土骨料组成，并进行改性处理。固体防冻剂以微小骨料的形态替代传统的微小气泡存在于抗冻混凝土中，提高其抗冻耐久性指标，即实现固废的高效利用，又解决了传统抗冻混凝土含气量不易控制的问题，有效保证了生产质量。
