摘要

人口、消费和经济的快速增长导致自然资源开采量的增加,通过产生废物和二氧化碳排放直接影响环境,尤其是在民用建筑行业。本研究旨在评估在土工聚合物砂浆试样中使用未经化学处理的粗碎轮胎橡胶废料替代细骨料的情况。研究采用了中心复合设计和响应面方法,以确定抗压强度、吸水率、空隙指数和比重的优化值。利用 X 射线衍射和扫描电子显微镜对土工聚合物砂浆试样进行了表征。最佳结果的优化参数是用轮胎橡胶废料替代 1%的细骨料、0% 的粗橡胶和大约 6 天的固化时间。这一组合的最佳值为:抗压强度 17.75 兆帕、吸水率 10.48%、空隙指数 18.58%、比重 1.77 克/立方厘米。模型的实验验证误差小于 10%。

Evaluation and Optimization of the Replacement of Fine Aggregate by Waste Tire Rubber in Geopolymer Mortar with Metakaolin

The rapid growth in population, consumption, and economy have led to an increase in the extraction of natural resources, directly influencing the environment by generating waste and CO2 emissions, particularly in the civil construction industry. The study aimed to evaluate the use of coarse and fragmented tire rubber waste, without chemical treatment, as a replacement for fine aggregate in geopolymeric mortar specimens. The central composite design, coupled with the response surface methodology, was used to determine the optimized values for compressive strength, water absorption, void index, and specific gravity. X-ray diffraction and scanning electron microscopy were used to characterize the geopolymeric mortar specimens. The optimized parameters for the best results were 1% replacement of fine aggregate with tire rubber waste, 0% coarse rubber, and approximately a 6-day curing time. This combination resulted in optimal values of 17.75 MPa for compressive strength, 10.48% for water absorption, 18.58% for void index, and 1.77 g/cm3 for specific gravity. The experimental validation of the models had an error of less than 10%.
