Composite anti-crack lightweight aggregate concrete and preparation method thereof
The invention belongs to the technical field of concrete, and particularly relates to composite anti-crack lightweight aggregate concrete and a preparation method thereof. The composite anti-crack lightweight aggregate concrete comprises the following raw materials in parts by weight: 45-60 parts of a cementing material; 20 to 30 parts of an admixture; 10 to 15 parts of lightweight aggregate; 2-4 parts of a polymer admixture; 1-3 parts of an air entraining agent; 30 to 40 parts of water; the preparation method comprises the following steps: adding the cementing material, the admixture, the lightweight aggregate, the macromolecular admixture and half of water into a stirrer according to the weight ratio, and uniformly stirring and mixing to obtain mixed slurry; uniformly mixing the air entraining agent and the balance of water, foaming, adding into the mixed slurry, and uniformly stirring to obtain the foaming agent. The composite anti-cracking lightweight aggregate concrete has good compressive strength and breaking strength, particularly has excellent anti-cracking performance, is light and high in strength after construction, does not have cracking and hollowing phenomena, can replace a traditional concrete material, and is widely applied to projects such as cushion layers, heat preservation and backfilling.
本发明属于混凝土技术领域，具体涉及一种复合抗裂轻集料混凝土及其制备方法。该复合抗裂轻集料混凝土，包括如下重量份原料：45‑60份胶凝材料；20‑30份掺合料；10‑15份轻集料；2‑4份高分子外加剂；1‑3份引气剂；30‑40份水；制备方法为：按重量配比，先将胶凝材料、掺合料、轻集料、高分子外加剂、二分之一的水加入到搅拌机中，搅拌混合均匀，得到混合浆料；将引气剂和余量水混合均匀发泡，再加入到混合浆料中，搅拌均匀，即得；该复合抗裂轻集料混凝土具有良好的抗压强度及抗折强度，尤其抗裂性能优异，施工后轻质高强，无开裂，无空鼓现象,可取代传统混凝土材料，广泛应用于垫层、保温、回填等工程。
