Recycled concrete composite material and preparation method thereof
The invention relates to the technical field of concrete preparation, in particular to a recycled concrete composite material which comprises concrete raw material powder, waste concrete aggregate, a reinforcing additive, a polymerization additive, density reinforcing powder, recycled rubber powder, structure bonding rubber powder and water. Wherein the mass percent of each component is as follows: the concrete raw material powder, the waste concrete aggregate, the reinforcing additive, the polymerization additive, the density reinforcing powder, the reclaimed rubber powder, the structure bonding rubber powder and the water. By adding the reinforcing additive, the polymerization additive, the density reinforcing powder, the regenerated rubber powder, the structure bonding rubber powder and other additives and repeatedly sieving and adjusting the density, the density of the regenerated concrete composite material is close to the apparent density of a conventional concrete material; the strength of the recycled concrete and the strength of the natural Portland cement concrete can be effectively ensured to be consistent, so that the concrete material can be used in building construction with relatively high mechanical structure stability requirements.
本发明涉及混凝土制备技术领域，尤其涉及一种再生混凝土复合材料，包括混凝土原料粉、废弃混凝土骨料、增强添加剂、聚合添加剂、密度增强粉末、再生胶粉、结构黏结胶粉和水；其中，各组分的质量百分比为：混凝土原料粉，废弃混凝土骨料，增强添加剂，聚合添加剂，密度增强粉末，再生胶粉，结构黏结胶粉和水。本发明通过增强添加剂、聚合添加剂、密度增强粉末、再生胶粉和结构黏结胶粉等添加剂的加入以及反复过筛密度调节，提高了再生混凝土复合材料的密度与常规混凝土材料的表观密度的接近度，能够有效保证再生混凝土的强度与天然硅酸盐水泥混凝土的强度保持一致，使混凝土材料在力学结构稳定性要求较高的建筑建设中得以使用。
