Using Waste Concretes as Recycling Aggregate in Concrete Production and Sustainability

Abstract

Protecting natural sources is an important responsibility for the whole world. Concrete is the most widespread construction material, as a result of its production, natural sources are running out, and also natural environment is being disturbed. In addition, building wastes brought about by the renovation activities for the structures that have expired. In order to maintain the ecological balance, using the available sources wisely and efficiently is crucial. In this study, known class and age of waste concrete is used as coarse and fine aggregates as production of concrete. There are two types of aggregates are used in concrete production as 0–4 and 4–22.4 sizes. These aggregates groups are replaced with normal aggregates as 0, 10, 20, 30, 40, 50 and 100% ratios in concrete. Compressive strength of concrete specimens are determined as 28 and 90 days coring regime. According to the experimental results, it has been seen that recycled aggregates may be used in concrete production and that they may shed light in the production of sustainable concrete.
