Compound fatty acid low-temperature phase-change cement concrete material and preparation method thereof
The invention belongs to the technical field of concrete materials, and discloses a compound fatty acid low-temperature phase-change cement concrete material and a preparation method thereof. The compound fatty acid low-temperature phase-change cement concrete material is prepared from, by weight, 100 parts of ordinary Portland cement, 337 parts of limestone, 190 parts of river sand, 40 parts of tap water, and 20 parts of a shaped composite phase change material. The preparation method of the compound fatty acid low-temperature phase-change cement concrete material comprises the following steps: weighing the raw materials according to the mixing ratio; pouring the shaped composite phase change material and river sand into a stirrer together, and performing stirring in advance; adding portland cement, limestone and tap water for mixing, and obtaining the compound fatty acid low-temperature phase-change cement concrete material. The phase-change concrete material disclosed by the invention can delay the time of starting to condense ice on the surface to a certain extent, so that an anti-freezing effect is achieved.
本发明属于混凝土材料技术领域，公开了一种复配脂肪酸低温相变水泥混凝土材料及其制备方法，所述复配脂肪酸低温相变水泥混凝土材料按重量份计，由以下原料制备而成：普通硅酸盐水泥100份；石灰岩337份；河砂190份；自来水40份；定形复合相变材料20份。所述复配脂肪酸低温相变水泥混凝土材料的制备方法包括以下步骤：按照配合比称取各原料；将定形复合相变材料与河砂一同倒入搅拌机，预先搅拌；再加入硅酸盐水泥、石灰岩和自来水进行拌合，即得复配脂肪酸低温相变水泥混凝土材料。本发明所述相变混凝土材料可以在一定程度上延缓表面开始凝冰的时间，从而达到抗凝冰的效果。
