Preparation method of cold-resistant anti-freezing concrete
The invention relates to a preparation method of cold-resistant anti-freezing concrete, which adopts wheat bran as a raw material to prepare a filler with high strength and good toughness, improves the compressive property of the concrete and reduces the mass loss rate, and adopts sodium hydroxide, urea and the like to prepare a response type concrete anti-freezing agent which can effectively reduce the freeze-thaw damage of the concrete. In addition, in the material mixing and stirring process, low-temperature heating is carried out, the false coagulation phenomenon of the materials when cement is added can be avoided, and the prepared concrete has high anti-freezing and cold-resistant performance.
本发明涉及一种抗寒防冻混凝土的制备方法，采用小麦麸皮作为原料制备出强度高、韧性好的填料，提升了混凝土的抗压性能，降低了质量损失率，采用氢氧化钠、尿素等制备得到响应型混凝土抗冻剂，能够有效降低混凝土的冻融损伤，延长使用寿命，并且在物料混合搅拌过程中，进行低温加热，能够避免投入水泥时，物料发生假凝现象，使得制备的混凝土具有较强的抗冻抗寒性能。
