High-weatherability low-shrinkage concrete and preparation method thereof
The invention discloses high-weatherability low-shrinkage concrete and a preparation method thereof, and relates to the technical field of polymer concrete. The high-weatherability low-shrinkage concrete is prepared from the following raw materials in parts by weight: 150 to 210 parts of ordinary Portland cement, 350 to 430 parts of coarse aggregate, 280 to 330 parts of fine aggregate, 40 to 50 parts of metakaolin, 70 to 80 parts of limestone powder, 20 to 30 parts of rice hull powder, 3 to 5 parts of polycarboxylate superplasticizer, 15 to 20 parts of composite expanding agent, 8 to 15 parts of vinyl acetate/diatomite hydrogel, 10 to 20 parts of polyaspartic acid ester resin; and 50 to 70 parts of water. The concrete is high in weather resistance and low in shrinkage, the concrete has excellent compressive strength and crack resistance, and the service life of the concrete is prolonged.
本发明公开一种高耐候性的低收缩混凝土及其制备方法，涉及高分子混凝土技术领域。本发明公开的高耐候性的低收缩混凝土是由以下重量份数的原料组成：普通硅酸盐水泥150‑210份、粗集料350‑430份、细集料280‑330份、偏高岭土40‑50份、石灰石粉70‑80份、稻壳粉20‑30份、聚羧酸减水剂3‑5份、复合膨胀剂15‑20份、乙酸乙烯/硅藻土水凝胶8‑15份、聚天门冬氨酸酯树脂10‑20份和水50‑70份。本发明提供了一种高耐候性、低收缩的混凝土，且该混凝土具有优异的抗压强度、抗裂性能，并延长了混凝土的使用寿命。
