Waste concrete-based recycled dry powder masonry mortar and preparation method thereof
The invention discloses waste concrete-based regenerated dry powder masonry mortar. The masonry mortar comprises the following components in parts by weight: 35-60 parts of concrete regenerated sand,40-65 parts of river sand, 20-25 parts of a cementing material and 0.04-0.1 parts of a composite additive, wherein the ratio of the total use amount of the concrete reclaimed sand and the river sand to the use amount of the cementing material is 100: (22.5-24.5), the ratio of the use amount of the cementing material to the use amount of the composite additive is 100: (0.2-0.4), the composite additive is a mixture of a water-retaining agent, a retarder and an excitant, and the ratio of the use amount of the water-retaining agent to the use amount of the retarder to the use amount of the excitant is (6-8): (10-14): (6-18). Correspondingly, the invention further discloses a preparation method of the waste concrete-based regenerated dry powder masonry mortar. By implementing the method, the dry powder masonry mortar with excellent workability, small consistency loss rate, high water retention rate and high strength can be obtained, and the requirements of normal construction and the requirements of strength and durability after mortar hardening are met.
本发明公开了一种废旧混凝土基再生干粉砌筑砂浆，其按照重量份计包括：混凝土再生砂35~60份，河砂40~65份，胶凝材料20~25份，复合添加剂0.04~0.1份；其中，混凝土再生砂与河砂的总用量：胶凝材料的用量=100：（22.5~24.5）；胶凝材料的用量：复合添加剂的用量=100：（0.2~0.4）；复合添加剂为保水剂、缓凝剂和激发剂的混合物；其中，保水剂的用量：缓凝剂的用量：激发剂的用量=（6~8）：（10~14）：（6~18）。相应的，本发明还公开了上述废旧混凝土基再生干粉砌筑砂浆的制备方法。实施本发明，可得到和易性优良、稠度损失率小、保水率和强度较高的的干粉砌筑砂浆，其满足正常施工需求及砂浆硬化后强度及耐久性的要求。
