Concrete recycled fine aggregate masonry mortar and preparation method thereof
The invention discloses concrete recycled fine aggregate masonry mortar and a preparation method thereof, and relates to the field of building materials, the concrete recycled fine aggregate masonry mortar comprises the following components by weight: 10%-18% of ordinary Portland cement, 0%-5% of recycled micro powder, 77%-90% of concrete recycled fine aggregate, and 0%-2% of an additive. According to the invention, the concrete recycled fine aggregate and the recycled micro powder are adopted, so that the construction waste can be reasonably recycled, the method is green and energy-saving, and compared with the common recycled fine aggregate, the concrete recycled fine aggregate has higher crushing value and lower stone powder content, so that the influence on the mortar performance is small when the masonry mortar is prepared; a proper amount of water reducing agent is added, so that the water demand of the mortar can be reduced, and the compressive strength of the masonry mortar is further improved.
本发明公开一种混凝土再生细骨料砌筑砂浆及其制备方法，涉及建筑材料领域，包括以下重量百分比的组分：普硅水泥10％‑18％、再生微粉0％‑5％、混凝土再生细骨料77％‑90％、外加剂0％‑2％。本发明采用混凝土再生细骨料和再生微粉，能够对建筑垃圾进行合理再利用，绿色节能，且相比于普通再生细骨料，混凝土再生细骨料的压碎值更高，石粉含量更低，因此在制备砌筑砂浆时对砂浆性能影响较小；并添加适量的减水剂，能够降低砂浆的需水量，进而提高砌筑砂浆抗压强度。
