Low-shrinkage anti-freezing concrete and preparation method thereof
The invention relates to the technical field of cement-based building materials, in particular to low-shrinkage anti-freezing concrete and a preparation method thereof.The SAP particles with the self-ablation characteristic are synthesized and added into the concrete, the shrinkage of the concrete is reduced by means of the characteristic that the SAP particles autonomously release water and ablate in the concrete, and the anti-freezing performance of the concrete is improved. Micropores formed by ablation provide a more favorable water freezing expansion space for the concrete in the freezing and thawing cycle process, and the anti-freezing performance of the concrete is greatly improved.
本发明涉及水泥基建筑材料技术领域，尤其是涉及一种低收缩抗冻混凝土及其制备方法，本发明通过合成一种具有自消融特性的SAP颗粒，并将其添加至混凝土中，利用其在混凝土自主释放水分并消融的特性，降低混凝土收缩，消融形成的微孔为混凝土在冻融循环过程中提供更为有利的水结冰膨胀空间，极大提高了混凝土的抗冻性能。
