Anti-crack and anti-rust method for large-volume facing concrete
The invention discloses an anti-crack and anti-rust method for large-volume facing concrete, and relates to the technical field of facing concrete.The large-volume facing concrete is prepared from, by weight, 30-40 parts of cement, 5-15 parts of microbeads, 5-15 parts of waste glass powder, 1-3 parts of hydrotalcite, 15-20 parts of water, 70-75 parts of fine aggregate, 90-100 parts of coarse aggregate and 1-1.5 parts of water reducing agent. The added microbeads with the volcanic ash effect and the waste glass powder can participate in secondary hydration of the concrete to generate hydrated calcium silicate with high compactness and high silicon-calcium ratio, so that the microstructure is improved, the matrix is compacted, the porosity is reduced, and the compressive strength, the breaking strength and the impermeability of the concrete are remarkably improved; calcined hydrotalcite which plays a key role in rust inhibition is added on the basis, and by means of the unique structural memory effect and ion exchange characteristics of the calcined hydrotalcite, the chloride ion binding capacity of the concrete is effectively improved, and the rust inhibition capacity is remarkably improved.
本发明公开了一种大体积饰面混凝土抗裂阻锈方法，涉及饰面混凝土技术领域，大体积饰面混凝土按重量份数计，包括以下组分：30～40份的水泥，5～15份的微珠，5～15份的废玻璃粉，1～3份的水滑石，15～20份的水，70～75份的细骨料，90～100份的粗骨料，1～1.5份的减水剂。加入的具有火山灰效应的微珠和废玻璃粉可以参与混凝土的二次水化，生成密实度高的高硅钙比水化硅酸钙，改善微观结构，密实基体，降低孔隙率，显著提高混凝土的抗压、抗折强度和抗渗性；在此基础上加入对阻锈起关键作用的煅烧水滑石，借助其独特的结构记忆效应和离子交换特性，有效提升混凝土氯离子结合能力，显著改善阻锈能力。
