Tank1, Maulik R. Joshi2, Hitesh K. Dhameliya3Strength and Durability Evaluation of Recycled,Aggregate strength, gradation, absorption, specific gravity, shape and texture are some of the physical and mechanical characteristics that contribute to the strength and durability of concrete. In general, the quality of recycled aggregate depends on the loading and exposure conditions of the demolished structures. Therefore, the experimental program was focused on the evaluation of physical and

Evaluation of Concrete Strength Made with Recycled

This paper, therefore, evaluated the feasibility of reusing waste concrete as recycled aggregate (RA) to produce concrete. The replacement levels were 20, 50, and 80% RA of normal coarse aggregate. Micro silica (MS) and fly ash (FA) were used as cementitious replacement material, however, the water-to-binder ratio (w/b) was kept constant at 0.31.An evaluation of the recycled aggregate characteristics,,20-04-2020· This review shows a consensus that the compressive strength of concrete decrease as the replacement rate of RA increase, irrespective of aggregate type and quality, as observed in all publications (except a RA generated from a high grade/quality source concrete and incorporated in a new low grade/quality concrete mixture).Durability evaluation of recycled aggregate concrete in a,,10-11-2020· Abstract. In the era of increasing consumption of natural aggregate, recycling construction wastes to prepare structural concrete is an effective measure to solve the dual pressure of resource shortage and environmental pollution. However, the utilization rate of recycled coarse aggregate (RCA) in China is still relatively low.
