Case Study Of Recycled Aggregate Concrete

the use of recycled aggregate concrete by mayuri,the results of the study show that the use of recycled aggregate concrete, if manufactured at industrial scale would be more expensive to purchase as a concrete product, compared to natural aggregate. the embodied emissions associated with the production processes does not differ much when the traditional and the alternative product is compared..case study – recycled material concrete production,concrete production in victoria relies on aggregate and cement sourced from natural and finite sand and rock deposits. these deposits are declining in viability; there is a shortage of quarry materials and natural sands. alternative sources of sands and aggregates are urgently required to meet forecasted consumption. outcomes and benefits.
