Durability of Concrete with Recycled Coarse Aggregates: Influence of Superplasticizers
Publication: Journal of Materials in Civil Engineering
Volume 26, Issue 7
Abstract
The use of recycled aggregates in concrete production can significantly contribute to its sustainability, but it may also jeopardize its durability. The use of superplasticizers may compensate for this performance handicap by contributing to the improvement of the inner structure of this type of concrete. The main goal of this study is to evaluate the effect of standard and high-performance superplasticizers on the key durability-related properties (shrinkage, water absorption by immersion and by capillarity, carbonation and chloride penetration resistance) of concrete made with different percentages of recycled coarse aggregates (RCA) from crushed concrete and compare the findings with the corresponding effect on conventional concrete. The overall conclusion is that recycled aggregate concrete is more susceptible to deterioration because of environmental conditions affecting this concrete’s durability performance more than that of conventional concrete. However, introducing superplasticizers in recycled aggregate concrete can help to enhance the concrete’s performance and offset this higher susceptibility.
