摘要

本研究的主要目的是利用不同的废内养护材料和外养护方法生产环保型铁水泥砂浆。采用不同体积替换率(5%、10%、15%)的细骨料对废砖和废瓷进行处理。此外,还使用了火山灰材料(硅灰和粉煤灰)。除了水固化的参考混合物外,还使用了四种不同的固化方法(空气、酥皮乳化沥青、蜡封漆和二氧化碳气体)。研究了不同龄期砂浆(7、14和28 d)的抗压、抗折强度和密度。结果表明:与对照材料相比,使用5%和10%的碎砖和5%和10%的陶瓷分别提高了33.3%和28%和25.3%和29%的二氧化碳固化铁水泥的抗压强度。添加10%的陶瓷时,其抗弯强度略有提高。结果表明,在生产过程中使用不同的废料,可提高水泥砂浆的成品质量。

Sustainable ferrocement mortar with different waste materials and curing methods
In this study, the essential aim is to produce an environment-friendly ferrocement mortar using different waste internal curing materials and external curing methods. Wastes of broken bricks and porcelanite were used with different volumetric replacement percentages (5%, 10%, and 15 %) of fine aggregate. Moreover, pozzolanic materials (silica fume and fly ash) were used. In addition to the water-cured reference mixture, four different curing methods (air, flan coat emulsified asphalt, wax sealing paint, and carbon dioxide gas (CO2)) were used. Compressive, flexural strength, and density for different ages of mortar (7, 14, and 28 d) were investigated. The outcomes demonstrate that, compressive strength of CO2-cured ferrocement improved by 33.3% and 28% when 5% and 10% of broken bricks was used and by 25.3% and 29% when 5% and 10% of porcelanite was used, respectively, than when the reference was used. The flexural strength was slightly improved when 10% porcelanite was used. Results demonstrate that the outcome ferrocement mortar was improved in spite of using different waste materials in production.
