After demolition of old roads and buildings, the removed concrete is often considered worthless and disposed of as demolition waste. By collecting the used concrete and breaking it up, recycled concrete aggregate (RCA) is created (Fig. 1).This paper focuses on coarse RCA which is the coarse aggregate from the original concrete that is …

To take benefit both from the GPC and recycled aggregate, it's a practical solution to use both together, i.e., use Geopolymer Concrete with Recycled Aggregate Concrete (GRAC). There are already several kinds of research going on for the use of GPC with Natural Aggregate (NA) and OPC with RA, but there are very few research on the …

Mix design of M20 grade concrete waste water treatment using constructed wetlands 14 M20 mix design was carried out according to Indian standards. The concrete mix was designed for slump of 60 mm. Concrete was designed with and without crushed coconut shell. Coconut shell replaced conventional aggregate by 10%, 20%, 30% and …

The possibility of utilizing recycled coconut shell aggregates in concrete as coarse aggregate is examined in the present study. An optimum percentage replacement of coarse aggregate with coconut shell aggregate is determined from the study. Coarse aggregate made from coconut shells were used in proportions of 5%, 10%, 15%, 20%, 25%, 30% …

The utilization of recycled aggregate is particularly very promising as 75 per cent of concrete is made of aggregates. In that case, the aggregates considered are slag, power plant wastes, recycled concrete, mining and quarrying wastes, waste glass, incinerator residue, red mud, burnt clay, sawdust, combustor ash and foundry sand.

This study is aimed to discuss the possibility to replacement of Natural Coarse Aggregate (NA) with Recycled Concrete Aggregate (RCA) in nominal concrete to observe the performance of Recycled Aggregate Concrete (RAC) towards sustainability point of view. An investigation is carried out to find the strength properties of RAC.
