Abstract

The production of adhesive mortar uses large proportions of sand, causing undesirable environmental impact as this is a finite resource. In recent years, the insertion of civil construction waste in cement matrixes has intensified with the objective of replacing sand in the mortar manufacturing process. Therefore, in this study, the proportions of 5%, 10%, 15% substitution of the mineral aggregate by basalt dust waste in the production of industrialized adhesive mortar were adopted. The reference mixture of 1:3 (cement: sand) was adopted and the water/dry material ratio was set at 0.20. The adhesive mortars produced in the tests to determine the consistency index, water retention, mass density, open time, tensile strength and water absorption by capillarity were analyzed. The results were satisfactory, demonstrating that it is feasible to use the waste as a substitute for sand in the production of industrialized adhesive mortars.
玄武岩粉部分替代矿物集料对工业化粘结砂浆生产的影响分析
粘合砂浆的生产使用了大量的沙子,造成了不理想的环境影响,因为这是一种有限的资源。近年来,为了在砂浆制造过程中取代沙子,民用建筑垃圾在水泥基质中的嵌入力度加大。因此,在本研究中,在工业化生产粘合砂浆时,采用玄武岩粉尘废料替代矿物骨料5%、10%、15%的比例。采用1:3(水泥:砂)的参考混合物,水/干材料比设定为0.20。分析了在测定稠度指数、保水性、质量密度、开启时间、抗拉强度和毛细吸水率的试验中生产的粘合砂浆。试验结果令人满意,表明利用这些废料代替沙子生产工业化粘结砂浆是可行的。
