Anti-freezing concrete and preparation method thereof
The invention discloses anti-freezing concrete and a preparation method thereof, and belongs to the technical field of building materials. The method comprises the following steps: selecting the following raw materials in proportion: 1012kg/m < 3 > of gravel, 196kg/m < 3 > of water, 570kg/m < 3 > of cement, and 622kg/m < 3 > of river sand and mPCM. Sequentially adding broken stones, river sand and cement into the stirrer, starting the stirrer, and stirring to obtain a concrete dry-mixed material; uniformly mixing water and mPCM, adding the mixture into the stirrer, and continuously stirring to obtain a concrete wet material; and pouring the concrete wet material into the test mold for curing and curing to obtain the concrete test piece. The preparation process is simple, and the anti-freezing performance of the concrete can be greatly improved by doping mPCM to replace part of river sand.
本发明公开了一种抗冻混凝土及其制备方法，属于建筑材料技术领域。选取以下配合比的原材料：碎石1012kg/m3、水196kg/m3、水泥570kg/m3，河砂和mPCM的质量总和为622kg/m3。依次向搅拌机中加入碎石、河砂和水泥，启动搅拌机，搅拌得到混凝土干拌料；将水和mPCM混合均匀后加入搅拌机中继续搅拌得到混凝土湿料；将混凝土湿料浇筑到试模中固化并养护，得到混凝土试件。本发明的制备工艺简单，通过掺杂mPCM取代部分河砂，可以大幅提高混凝土的抗冻性能。
