Cement-based recycled mortar with granite waste powder cooperating with mineral powder and preparation method of cement-based recycled mortar
The invention discloses cement-based recycled mortar with granite waste powder cooperating with mineral powder and a preparation method of the cement-based recycled mortar. The cement-based recycled mortar comprises the following components in percentage by weight: 1%-5% of granite waste powder, 10%-25% of mineral powder, 5%-10% of cement, 20%-45% of natural fine aggregate, 10%-30% of recycled fine aggregate, 0.5%-1% of a water reducing agent, 0.5%-1% of an antirust agent, 3%-5% of anhydrous sodium silicate and 10%-25% of water. The mortar can save the consumption of cement and natural aggregate, promote the resource utilization of solid waste, reduce the emission of carbon dioxide, is green and environment-friendly, and has favorable cohesiveness and water retention property; and the relative water demand is small, the mortar workability is good, and the dosage of an alkali-activated material is reduced.
本发明公开了一种花岗岩废粉协同矿粉的水泥基再生砂浆及其制备方法。花岗岩废粉协同矿粉的水泥基再生砂浆，按重量百分比计，它由以下组分组成：花岗岩废粉1％～5％、矿粉10％～25％、水泥5％～10％、天然细骨料20％～45％、再生细骨料10％～30％、减水剂0.5％～1％、防锈剂0.5％～1％、无水硅酸钠3％～5％、水10％～25％。该砂浆可节约水泥和天然骨料用量，促进固体废弃物的资源化利用，减少了二氧化碳的排放，绿色环保，具有良好的粘聚性与保水性；相对需水量小，砂浆和易性好，减少碱激发材料的用量。
