Obviously, use of such wastederived manufactured aggregate in place of aggregate from natural sources is a big step towards sustainability. Yet, BIS has restricted the extent of their utilisation, 20 per cent in case of RCA for RCC of concrete Grade M25.

The grading curve for the aggregates falls within the lower and upper limit of the grading requirement for aggregate from natural sources BS 882 (1992). This implies that the aggregates are suitable for construction work. However, the grading curve for crushed granite (Figure 2) shows a reasonable fall out from the gradation limit and a ...

The effects of aggregatetocement (A/C) ratios and types of aggregates on the properties of precast concrete blocks are evaluated in this study. A/C ratios between three and six and three types of aggregates (, natural crushed aggregate (NCA), recycled crushed aggregate (RCA) and recycled crushed glass (RCG)) were used in the experiments.
RecycledConcrete Aggregate. Recycledconcrete aggregate generally has a higher absorption and a lower specific gravity than conventional aggregate. Absorption values typically range from 3% to 10%, depending on the concrete being recycled; this absorption rate lies between those for natural and lightweight.
