Premixed mortar and application thereof
The invention relates to a premixed mortar. The premixed mortar comprises main materials and auxiliary materials, and the main materials comprise, by weight, 12-17% of a cementing material, 12-17% of a doping material and 68-71% of recycled aggregate; the auxiliary materials comprise 0.02% of a water-retaining agent, 0.025% of a water reducing agent and 0.01% of polyvinyl alcohol according to the total weight fraction of the ready-mixed mortar; and the cementing material is slag Portland cement and/or Portland cement, the recycled aggregate is one or two of concrete recycled aggregate and red brick recycled aggregate, the doping material is secondary fly ash, the particle size of the recycled aggregate is 0-10 mm, the recycled aggregate is subjected to high-temperature calcination and cooling before being prepared into the ready-mixed mortar, the high-temperature calcination temperature is 1330 DEG C, and and the calcination time is 80 minutes. According to the premixed mortar disclosed by the invention, the recycled concrete is fully utilized as the aggregate, and the red brick recycled aggregate is also utilized, so that a recycling way is found for a large amount of red brick construction waste.
本发明涉及一种预拌砂浆，包含主料和辅料，其中，主料包含按重量分数计的以下材料：胶凝材料12～17％，摻合料12～17％，再生骨料68～71％；按预拌砂浆总重量分数计，辅料包含保水剂0.02％，减水剂0.025％，聚乙烯醇0.01％；胶凝材料为矿渣硅酸盐水泥和/或硅酸盐水泥，再生骨料为混凝土再生骨料和红砖再生骨料中的一种或两种，摻合料为二级粉煤灰，再生骨料颗粒粒径为0～10mm，再生骨料制备成预拌砂浆前经过高温煅烧降温冷却，所述高温煅烧温度为1330℃，煅烧时间为80min。本发明预拌砂浆不仅仅充分利用再生混凝土做骨料，更使用了红砖再生骨料，为大量的红砖建筑垃圾找到的再利用的途径。
