Abstract

Usage of single use plastics has been rapidly increasing in the recent past and it is challenging to dispose of these plastics safely, since they are non-biodegradable. Especially, Polyethylene Terephthalate (PET) which is widely used in the form of water bottles cannot be easily recycled or reused. On the other hand, construction projects require sustainable materials having good strength, accordingly various studies have been conducted to reuse plastic wastes in the concrete and positive results have been obtained. In this study, the crushed PET bottles are partially substituted with fine aggregates and water hyacinth is added as a bio plasticizer in concrete. The concrete specimens are cast by substituting PET aggregates with the fine aggregates at 2, 4, 6, 8, 10% and water hyacinth is added at 10 & 20% by weight of water. The specimens are tested and it is noted that with the addition of PET aggregates up to 4% the strength of the concrete increases and beyond 4%, strength of the concrete gradually decreases, and addition of water hyacinth enhances the strength of the concrete.

PET骨料替代细骨料、水葫芦替代生物增塑剂在混凝土中的试验研究

近年来，一次性塑料的使用迅速增加，由于这些塑料不可生物降解，因此安全处理这些塑料具有挑战性。特别是，广泛用于水瓶的聚对苯二甲酸乙二醇酯(PET)不易回收或再利用。另一方面，建筑项目需要具有良好强度的可持续材料，因此人们进行了各种研究，以再利用混凝土中的塑料废物，并取得了积极的成果。在本研究中，用细骨料代替部分破碎的PET瓶，并在混凝土中加入水葫芦作为生物增塑剂。用2、4、6、8、10%的细骨料代替PET骨料浇筑混凝土试件，水葫芦添加量为水重量的10、20%。试验结果表明，当PET骨料掺入量达到4%时，混凝土强度增加，超过4%后，混凝土强度逐渐降低，水葫芦的掺入提高了混凝土的强度。

期刊介绍： International Review of Applied Sciences and Engineering is a peer reviewed journal. It offers a comprehensive range of articles on all aspects of engineering and applied sciences. It provides an international and interdisciplinary platform for the exchange of ideas between engineers, researchers and scholars within the academy and industry. It covers a wide range of application areas including architecture, building services and energetics, civil engineering, electrical engineering and mechatronics, environmental engineering, mechanical engineering, material sciences, applied informatics and management sciences. The aim of the Journal is to provide a location for reporting original research results having international focus with multidisciplinary content. The published papers provide solely new basic information for designers, scholars and developers working in the mentioned fields. The papers reflect the broad categories of interest in: optimisation, simulation, modelling, control techniques, monitoring, and development of new analysis methods, equipment and system conception.
