High-performance recycled fine aggregate premixed mortar and preparation process thereof
The invention discloses high-performance recycled fine aggregate premixed mortar and a preparation process thereof, which are applied to the technical field of recycled fine aggregate premixed mortar, the premixed mortar prepared by the method is light in weight, high in early strength, good in workability and greatly improved in water-retaining property, and compared with the prior art, the adhesive force of hardened mortar and a matrix is improved, and the service life of the mortar is prolonged. The mortar also has the advantages of high construction efficiency and good integrity, simultaneously uses two industrial solid wastes of construction waste and nickel slag as raw materials, saves cost, is beneficial to environmental protection, has the effects of dispersing a mortar cementing material and maintaining the plasticity of mortar, ensures the fluidity and cohesive force of the mortar at the same time, and has a good application prospect. Therefore, the phenomena of hollowing and cracking of the mortar are effectively avoided, and the consistency loss rate of the mortar after 24 hours can be effectively reduced.
本发明公开了一种高性能再生细骨料预拌砂浆及其制备工艺，应用在再生细骨料预拌砂浆技术领域，本发明通过此法制备的预拌砂浆重量轻、早期强度高、和易性好，保水性大大提高，与现有技术相比，提高硬化砂浆与基体的粘结力,还具有施工效率高，整体性好的优点,同时使用建筑垃圾和镍渣两种工业固体废弃物为原料，节省成本，且有利于保护环境，并且具有分散砂浆胶凝材料、保持砂浆塑性的作用，同时保证了其流动性和粘结力，从而有效地避免砂浆空鼓、开裂现象的发生，可有效降低砂浆24h后的稠度损失率。
