Environment-friendly masonry mortar and preparation method thereof
The invention discloses environment-friendly masonry mortar and a preparation method thereof. The environment-friendly masonry mortar provided by the invention comprises the following components in parts by weight: 0-20 parts of ordinary Portland cement; 8-20 parts of high-calcium desulfurization ash; 8-20 parts of mineral powder; 5-15 parts of steel slag powder; 20-65 parts of fine aggregate; 0-8parts of an alkaline activator; 1-5 parts of a water reducing agent; and 1-3 parts of a water retention thickening agent. The method has the beneficial effects that the high-calcium desulfurized flyash is used for alkali activation, so that the mixing amount of an alkali activator is reduced, and the energy is saved; furthermore, the defects of high cement consumption, high energy consumption, serious additional pollution and the like of the conventional mortar are overcome, and industrial wastes are utilized to the maximum extent. According to the invention, the problems of low strength, poor water resistance, air shrinkage cracking and the like of the existing environment-friendly mortar can be improved; all the raw materials are provided in the form of dry powder, are mainly from industrial wastes, and have the advantages of wide sources, low cost, energy saving and environmental protection.
本发明公开了一种环保型砌筑砂浆及其制备方法。本发明的环保型砌筑砂浆按重量份数计包括以下组分：普通硅酸盐水泥：0～20份；高钙脱硫灰：8～20份；矿粉：8～20份；钢渣粉：5～15份；细骨料：20～65份；碱性激发剂：0～8份；减水剂：1～5份；保水增稠剂：1～3份。本发明具有如下有益效果：利用高钙脱硫灰进行碱激发，减少了碱激发剂的掺量，节约了能源；克服了现有砂浆水泥用量大、能耗大、附加污染严重等缺陷，最大限度利用工业废弃物；可改善现有环保型砂浆存在的强度低、耐水性不好、干缩开裂等问题；所有原材料以干粉的形式提供，材料主要来自工业废弃物，具有来源广泛、成本低廉、节能环保的优点。
