Experimental study on strength behaviour of recycled,
recycled-aggregate concrete by in-situ tests”. The compressive strength of concrete was determined at various ages up to 90 days using 100mm cubes. Based on the results, they concluded that for a given water-cement ratio, the recycled-aggregate concrete showed a lower strength than that for the natural aggregate concrete.Experimental study on strength behaviour of recycled,,10-03-2013· the research has been conducted by song gu et al. on properties of recycled aggregate concrete concluded that, because of old mortars adhered on the surface of the aggregate the water absorption rate of recycled aggregate is far more than natural aggregates,the slump and strength will decrease while the replacement rate of rca increasedCarbonation behaviour of recycled aggregate concrete,,01-09-2015· The literature review has shown that recycled aggregate concrete (RAC) tends to exhibit greater carbonation than a corresponding natural aggregate concrete (NAC), and that the magnitude of the difference depends on several factors related to the use of RA that are discussed in the following sections. 3.1.
