Preparation method of waste concrete block regenerated dry powder masonry mortar
The invention discloses a preparation method of waste concrete block regenerated dry powder masonry mortar, which is prepared from the following raw materials in parts by weight: 80 to 100 parts of waste concrete block, 2 to 3 parts of fiber composition, 0.1 to 0.15 part of methyl hydroxypropyl cellulose ether, 13 to 15 parts of cement, 0.2 to 0.3 part of air entraining agent and 5 to 7 parts of coal ash, the air entraining agent comprises sodium alpha-olefin sulfonate, fatty alcohol-polyoxyethylene ether and sodium lignin sulfonate according to the mass ratio of 1: (5-6): (2-2.8), the adhesion of the dry-powder masonry mortar is improved through reasonable proportioning of the raw materials, meanwhile, the water retention effect and the setting time of the mortar are improved, the construction time of the mortar is prolonged, and the bonding strength and the compressive strength of the dry-powder masonry mortar are improved.
本发明公开了一种废混凝土块再生干粉砌筑砂浆的制备方法，按重量份计，原料包括废混凝土块80‑100份、纤维组合物2‑3份、甲基羟丙基纤维素醚0.1‑0.15份、水泥13‑15份、引气剂0.2‑0.3份和粉煤灰5‑7份，所述引气剂包括质量比为1:5‑6:2‑2.8的α‑烯基磺酸钠、脂肪醇聚氧乙烯醚和木质素磺酸钠，通过原料合理配比提高干粉砌筑砂浆的黏着性，同时改善砂浆的保水效果和凝固时间，延长砂浆的施工时间，提高粉砌筑砂浆的粘结强度和抗压强度。
