The invention discloses recycled fine aggregate wet-mixed mortar and a preparation method thereof. The wet-mixed mortar comprises the following components in parts by mass: 8-10 parts of cement, 3-4 parts of fly ash, 75-78 parts of recycled fine aggregate, 0.3-0.5 part of a plastic stabilizer for recycled fine aggregate mortar, 5-15 parts of ceramic powder, 0.45-0.55 part of a mortar conditioning agent, 10-11 parts of water, 0.4-0.8 part of polypropylene fiber and 0.2-0.4 part of carbon fiber, wherein the particle size of the recycled fine aggregate is less than 3.5 mm, and the fineness modulus is 2.1-2.3. According to the invention, by adopting a special recycled fine aggregate production process and the admixture for the recycled fine aggregate wet-mixed mortar, it can be ensured that the working performance of the recycled fine aggregate wet-mixed mortar is good and the technical indexes such as strength, shrinkage rate and the like meet the relevant standard requirements, the risk of mortar cracking and hollowing are reduced, the utilization rate of the building solid waste and the waste concrete can be improved, and resources are greatly saved.
本发明公开了一种再生细骨料湿拌砂浆及其制备方法，湿拌砂浆按质量份数计包含有：水泥8～10份、粉煤灰3～4份、再生细骨料75～78份、再生细骨料砂浆用稳塑剂0.3～0.5份、陶瓷粉5～15份、砂浆调节剂0.45～0.55份、水10～11份、聚丙烯纤维0.4～0.8份、碳纤维0.2～0.4份，再生细骨料粒径小于3.5mm，细度模数为2.1～2.3；本发明通过采用特殊的再生细骨料生产工艺和再生细骨料湿拌砂浆用外加剂，可以保证再生细骨料湿拌砂浆的工作性能良好和强度、收缩率等技术指标满足相关标准要求，降低砂浆开裂和空鼓的风险，又能提高建筑固体废弃物和废弃混凝土的利用率，大大节约资源。
