Masonry mortar and preparation method thereof
The invention discloses a masonry mortar and a preparation method thereof. The masonry mortar comprises following components in parts by weight: 1 to 5 parts of modified waste paper fiber-titanium dioxide composite material with a nano hollow structure, 15 to 55 parts of cement, 30 to 80 parts of graded sand, 0 to 8 parts of mineral admixture, 0.5 to 5 parts of a water-retaining thickening material and 1 to 3 parts of a water reducing agent. The invention also discloses a preparation method of the masonry mortar. Through the crack bridging effect of modified waste paper fibers, early shrinkageis slowed down, and the volume stability is improved. The masonry mortar also has the advantages of light self-weight, excellent impermeability and increased compression-bending ratio, and the toughness of the mortar is improved. Water in the modified waste paper fibers is released, so that hydration of cement in the later period is promoted. In addition, the anti-seepage performance is good, andthe masonry motor also has a soundproof effect.
本发明公开了一种砌筑砂浆及其制备方法，以重量计，包括以下组分：具有纳米中空结构的改性废纸纤维‑二氧化钛复合材料1‑5份、水泥15‑55份、级配砂30‑80份、矿物掺合料0‑8份、保水增稠材料0.5‑5份及减水剂1‑3份。本发明还公开了该砌筑砂浆的制备方法。本发明公布的砌筑砂浆通过改性废纸纤维的裂缝桥接作用，减缓早期收缩，提高体积稳定性；砌筑砂浆还具有自重轻，抗渗性能优异，压折比有所提高，改善砂浆的韧性；通过释放改性废纸纤维中的水分，促进后期水泥水化等优点。此外还具有抗渗性能好，具有一定的隔声效果。
