摘要

城市的扩张导致了与废物堆积和缺乏管理控制有关的问题,巴西仍然有大约2400个垃圾场或不受控制的垃圾填埋场。有大量的聚对苯二甲酸乙二醇酯(PET)被不当丢弃。相应地,建筑行业也一直在寻找可持续生产混凝土的方法。这项工作涉及到在混凝土中以5%和15%的比例替代PET作为细骨料的分析。PET颗粒在2.36 mm开孔筛中通过率超过75%,在0.15 mm开孔筛中保留粒径的99%以上。对混凝土性能、抗压强度、抗拉强度、吸水率和孔隙率进行了评价,并与参考配合比进行了比较。共使用45个混凝土浇筑试件完成试验。结果表明,以PET为细集料的混合料组成降低了抗压强度和抗拉强度,提高了吸水率和孔隙指数。结果表明,以PET为细集料的共混组合物抗压强度降低约14%,抗拉强度降低约7-11%,孔隙率提高约20%,吸水率提高约30%。

Concrete with partial replacement of natural aggregate by PET aggregate—An exploratory study about the influence in the compressive strength
The expansion of cities contributed to the problems related to the accumulation of waste and lack of control over its management, there are still around 2400 dumps or uncontrolled landfills in Brazil. There is a large volume of polyethylene terephthalate (PET) improperly discarded. In turn, the construction industry has been looking for sustainable ways to produce concrete. This work deals with the analysis of the replacement of PET as a fine aggregate in concrete in the proportions of 5% and 15%. PET particles pass more than 75% in the 2.36 mm opening sieve and have more than 99% of their particle size retained in the 0.15 mm opening sieve. Concrete properties, compressive strength, tensile strength, water absorption and void ratio were evaluated and compared with the reference mix. In total, 45 specimens cast in concrete were used to complete the experiment. The results obtained showed that mixture compositions that incorporate PET as fine aggregates decrease compressive and tensile strength, increase water absorption and void index. The results obtained showed that blending compositions that incorporate PET as fine aggregates decrease compressive strength in about 14%, decrease tensile strength in about 7–11%, increased the void ratio in almost 20% and increased the water absorption in about 30%.
