Novel dry-mixed masonry mortar
The invention discloses a novel dry-mixed masonry mortar. The formula of the novel dry-mixed masonry mortar comprises limestone, limestone tailings, iron tailings, yellow sand, cement, expanded perlite, an anti-cracking agent, a thickening agent and a modifier. The weight parts of the components are respectively as follows: 20-30 parts of limestone, 0.7-0.8 parts of limestone tailings, 8-10 parts of iron tailings, 25-30 parts of yellow sand, 9-15 parts of cement, 3-5 parts of expanded perlite, 0.2-0.3 parts of an anti-cracking agent, 0.2-0.3 parts of a thickening agent and 0.2-0.3 parts of a modifier, and the anti-cracking agent is prepared by mixing coal ash powder and polypropylene fiber according to the weight ratio of 9: 1; according to the novel dry-mixed masonry mortar, the limestone tailings and the iron tailings are used as raw materials for preparing the masonry mortar, resources can be fully utilized, meanwhile, the production cost is reduced, and in the production process, raw materials with different particle sizes are prepared and then mixed for preparation, the friction force between different granularities of the masonry mortar in the using process is increased, and the quality of the masonry mortar is improved.
本发明公开了一种新型干混砌筑砂浆，配方包括：石灰石、石灰石尾矿、铁尾矿、黄砂、水泥、膨胀珍珠岩、抗裂剂、稠化剂和改性剂；各组分的重量份数分别是：20‑30份的石灰石、0.7‑0.8份的石灰石尾矿、8‑10份的铁尾矿、25‑30份的黄砂、9‑15份的水泥、3‑5份的膨胀珍珠岩、0.2‑0.3份的抗裂剂、0.2‑0.3份的稠化剂和0.2‑0.3份的改性剂，抗裂剂是由煤灰粉和聚丙烯纤维按照重量9∶1混合制备而成；该新型干混砌筑砂浆，通过将石灰石尾矿以及铁尾矿当做制备砌筑砂浆的原料，有利于充分的利用资源，同时降低了生产成本，且在生产的过程中，通过制备不同粒度的原料随后混合制备，增加了该砌筑砂浆在使用过程中不同粒度之间的摩擦力，提高了该砌筑砂浆的品质。
