Anti-freezing and anti-cracking concrete composite material and preparation method thereof
The invention relates to the technical field of preparation of anti-freezing and anti-cracking concrete, and discloses an anti-freezing and anti-cracking concrete composite material. Comprising the following components: 15%-25% of cement, 20%-30% of sand, 20%-30% of gravel, 5%-10% of a concrete admixture, 1%-5% of an anti-freezing agent, 1%-3% of a silane modifier, 0.5%-2% of a fiber reinforcing agent and 0.5%-2% of an anti-cracking agent. Comprising the following steps: S1, pretreating cement, sand, gravel, a concrete admixture, an anti-freezing agent, a silane modifier, a fiber reinforcing agent, an anti-cracking agent, diatom ooze, diatom acid salt microspheres, a microcapsule phase change material, calcium silicate crystals and graphene oxide. By adding the diatom ooze, the diatom acid salt microspheres, the microcapsule phase change material and other components, the freezing resistance of the concrete is effectively improved, and the damage of the concrete in a freezing and thawing cycle can be reduced, so that the freezing resistance of the concrete is improved.
本发明涉及防冻防裂混凝土制备技术领域，公开了一种防冻防裂混凝土复合材料，按重量百分比计，包括以下组份：15％‑25％的水泥、20％‑30％的砂、20％‑30％的碎石、5％‑10％的混凝土外加剂、1％‑5％的防冻剂、1％‑3％的硅烷改性剂、0.5％‑2％的纤维增强剂、0.5％‑2％的抗裂剂，还公开了一种防冻防裂混凝土复合材料制备方法，包括以下步骤：S1.将水泥、砂、碎石、混凝土外加剂、防冻剂、硅烷改性剂、纤维增强剂、抗裂剂、硅藻泥、硅藻酸盐微球、微胶囊相变材料、硅酸钙晶体、石墨烯氧化物进行预处理。通过添加硅藻泥、硅藻酸盐微球、微胶囊相变材料等组分，有效提高了混凝土的耐冻性能，能够减少混凝土在冻融循环中的损伤，从而提高其耐冻性能。
