Kedar "Comparison of Strength Characteristics of Concrete by using Fly Ash and Rice Husk Ash" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-5 | Issue-1, December 2020, pp.564-565, URL: https://www.ijtsrd.com/papers/ijtsrd37993.pdf

A state of extreme landfill areas redevelopment program in many parts of the country has cause to bring the use of recycled aggregate. The low quality of recycled aggregate has limited its use to low-grade applications such as roadwork sub-base and pavements, while its adoption for higher-grade concrete is rare because of the lower compressive strength and higher variability in mechanical performance of recycled aggregate. A new concrete mixing method, that is the two-stage mixing approach (TSMA), was publically recommends to improve the quality of recycled aggregate concrete (RAC) by splitting the mixing process into two stages. The variation of compressive strength by experimental analysis involving the new mixing method with the two-stage mixing approach by proportioning ingredients with the percentage of recycled coarse aggregates (RCA), fly ash and rice husk ash. Based on experiments and results, improves strength to RAC were achieved with TSMA. This can be regarded as to the porous nature of RA and the mixing process that fills up some of its pores and cracks, resulting in a denser aggregate and concrete. An improved zone of RA gives a more strength than the normal mixing approach.
