Abstract
—As increasing durability of materials is considered an important tool to improve sustainability, the durability of concrete produced using recycled aggregates was investigated. Physical and chemical properties of crushed concrete aggregates were assessed and compared to those of fresh aggregates. Concrete samples were produced using different water to cement ratios and were tested for absorption, density, compressive strength, tensile strength and flexural strength. Cubes were cast and subjected to different exposure conditions up to one year, before being tested. The considered exposure conditions include fresh water, open air, sea water and burying samples underground. Samples were tested for compressive strength, absorption and specific gravity. Although aggregates from demolished concrete were found to be inferior to new aggregates in terms of absorption, abrasion resistance and impact resistance, the durability of concrete produced using recycled concrete as aggregates was found to be comparable to this of concrete produced using fresh aggregates.
