Abstract

The paper describes a new model of concrete production, which contains a glass cullet. A worn-out car side window have been used for the production of recycled glass aggregate (RGA) and its properties were examined. The RGA was used in concrete as a 50% and 100% mass substitute of the traditional aggregate. Basic tests of fresh concrete mix and hardened concrete were carried out. The consistency, the air content in the concrete mix, the density of hardened concrete, water absorption, water resistance, frost resistance, and the compressive strength (after 9, 28, and 90 days) were evaluated. Composite samples were also subjected to microscopic analysis. The results showed that the RGA can be recommended as an aggregate for concretes, and the features of the RGA concrete are more favorable than those of traditional concrete. The microscopic analyses allowed us to identify the reasons for improving the properties of the RGA composites.

摘要

本文描述了一种包含碎玻璃的新型混凝土生产模型。一块破旧的汽车侧窗玻璃被用于生产再生玻璃骨料（RGA），并对其性能进行了检测。RGA在混凝土中用作传统骨料的质量替代物，替代比例分别为50%和100%。对新拌混凝土和硬化混凝土进行了基本试验。评估了混凝土拌合物的稠度、含气量、硬化混凝土的密度、吸水率、耐水性、抗冻性以及抗压强度（9天、28天和90天后）。还对复合样品进行了微观分析。结果表明，RGA可推荐用作混凝土骨料，且RGA混凝土的性能比传统混凝土更优。微观分析使我们能够确定RGA复合材料性能改善的原因。
