Masonry mortar formula and preparation method thereof
The invention discloses a masonry mortar formula and a preparation method thereof. The masonry mortar formula is characterized in that the masonry mortar is prepared from 15-25 parts of Portland cement, 20-30 parts of silt sand, 1-5 parts of mineral admixture, 30-40 parts of artificial sand, 10-15 parts of construction waste powder, 4-9 parts of calcium enhancer, 0.5-1.5 parts of redispersible latex powder, 0.75-0.9 part of concrete admixture, 0.1-0.5 part of cellulose ether and 0.1-0.5 part of air entraining agent, wherein the cellulose ether is hydroxypropyl methyl cellulose, the concrete admixture is a naphthalene-based superplasticizer, and the naphthalene-based superplasticizer is powder. According to the formula of the masonry mortar and the preparation method of the masonry mortar, by changing the content of the construction waste powder, adding the mineral admixture and the concrete admixture and adding the air entraining agent, bleeding and segregation of concrete can be reduced, the homogeneity of the concrete is improved, and the concrete admixture can be used for preparing large-flow-state concrete; and cast-in-place concrete and prefabricated parts with the requirements for early strength and high strength have a good using effect, and various properties of the concrete can be comprehensively improved.
本发明公开了一种砌筑砂浆的配方及其制作方法，其特征在于：硅酸盐水泥15‑25份、淤泥砂20‑30份、矿物外加剂1‑5份、人工砂30‑40份、建筑垃圾粉料10‑15份、增钙剂4‑9份、可再分散乳胶粉0.5‑1.5份、混凝土外加剂0.75‑0.9份、纤维素醚0.1‑0.5份、引气剂0.1‑0.5份，所述纤维素醚为羟丙基甲基纤维素，所述混凝土外加剂为萘系高效减水剂，且萘系高效减水剂为粉剂。本发明所述的一种砌筑砂浆的配方及其制作方法，该砌筑砂浆的配方通过改变建筑垃圾粉料含量，添加矿物外加剂和混凝土外加剂，并添加引气剂，能够减少混凝土泌水和离析，提高混凝土的均质性，混凝土外加剂对配制大流态砼，有早强、高强要求的现浇砼和预制构件，有很好的使用效果，可全面提高和改善砼的各种性能。
