Anti-freezing concrete and preparation method thereof
The invention relates to an anti-freezing concrete and a preparation method thereof, and belongs to the technical field of concrete preparation. Wheat bran is used as a raw material; ammonium sulfateprecipitate is extracted by adopting a phosphate buffer salt solution to prepare antifreeze protein, the prepared antifreeze protein and silicone rubber are compounded to prepare composite fibers by adopting electrostatic spinning, and the composite fibers are taken as a filler of the high-strength antifreeze concrete so as to prepare the high-strength antifreeze concrete with light weight, good elasticity, toughness, durability and shock absorption performance. The prepared anti-freezing concrete has an excellent compression resistant and anti-freezing performance, under the condition that the compression resistance of the concrete is not changed, the larger the mass loss rate is, the poorer the anti-freezing performance is, and otherwise, the better the anti-freezing performance is.
本发明涉及一种抗冻混凝土及其制备方法，属于混凝土制备技术领域。本发明以小麦麸皮为原料，采用磷酸缓冲盐溶液提取硫酸铵沉淀制备抗冻蛋白，将制备的抗冻蛋白和硅橡胶复合采用静电纺丝制备出复合纤维，作为高强度抗冻混凝土的填料，制备出一种具有轻质、良好弹性、韧性、耐久性和减震性能的高强度抗冻混凝土；本发明制备的抗冻混凝土具有优异的抗压抗冻性能，混凝土抗压性不变的情况下，质量损失率越大，说明抗冻性能越差，反之，抗冻性能越好。
