A Review on the Use of Recycled Aggregate in Concrete

2010-9-16  Although recycled aggregate of Classes RCA(I), (II) or (III) can be used in concrete, the quality and grading of the recycled aggregate have to meet the requirements as specified in BS 882 (BSI 1992). For the aggregate, which fails to comply with the grading requirements in BS 882 (BSI 1992), may still be used in concrete provided that the quality of the aggregate is in compliance with BS 5328 (BSI 1997) and trial mixes indicate that concrete of suitable quality can be produced. However, recycled aggregate, which has particle size less than 5 mm, is not recommended for the use in concrete because it would cause an increase in the water content and contain a high level of contamination. Nevertheless, a 10 % replacement of natural sand by recycled fine aggregate is permitted in some situations where a high degree of control exists. (i.e. fines from reclaimed product at a precast concrete

A Review Paper on use of Recycled Aggregates in Concrete

2019-7-1  The need and importance of concrete in construction industry is ever increasing. Recycled Aggregate Concrete (RAC) is concrete that using Recycled Aggregate (RA) as partially or fully replacement in coarse and fine aggregate. It is believed RA have been used from 1945 in concrete producing and started when World War II damaged a large quantity of concrete structures and the high demand of aggregate to rebuild the structures. Concrete is the favorite choice as a construction material among civil engineersaround the globe for decades. It is preferred for its better performance, longer life and low maintenance cost. To achieve rapid urbanization every year smaller structures are demolished andnewer and bigger ones are constructed. These demolished materials (majority of which is usually concrete) are often dumped on land and is not reused for any purpose. This practice affects the fertility of land. With the wave of sustainability also impacting the construction industry, scientist and engineers throughout the world are looking for sustainable and reusable construction materials. One such material is recycled aggregate concrete. Utilizing recycled aggregate
