Development of Cement Concrete Using Granite Dust and Fly Ash as Partial Substitutes

Abstract

In this scenario, we observe how the strength of the concrete changes when the standard cement is switched out for granite powder and fly ash as the fine aggregate. In this particular investigation, the researchers employed anything from zero to fifty percent fine aggregate and whatever quantity of cement they deemed appropriate. Concretes of grade M25 and M60 are used since there is a need to take into account either low and high strengths. At room temperature, compressive testing was carried out on cubes of fly ash-added concrete that had been aged 7, 14, 28, and 90 days respectively. After 14 and 28 days after being mixed, cylinders of fly ash-added concrete were split and evaluated for their tensile strength. During a cure period of 28 days submerged in water, the flexural strengths of the concrete beams were measured. We were able to evaluate the chemical solution resistance of concrete made with fly ash and quarry dust by curing samples of concrete in a variety of chemical solutions and then determining the amount of strength and weight that was lost as a result. The high performance concrete mix that was created was made using the M60 grade of concrete. The major focus of this investigation is on the characteristics and performance of concrete in which the cement and fine aggregate have been partly substituted by large volume fly ash (HFA) and quarry dust (QD). The strength, stiffness, and residual strength of high-performance reinforced concrete beams were investigated and tested to see how they would perform under cyclic loading circumstances in terms of the deterioration of these properties. In this investigation, the researchers used a sophisticated chloride penetration technique to concrete that was produced using a combination of fly ash and quarry dust (RCPT). Last but not least, research was conducted on the compressive, split tensile, and flexural strengths, in addition to the chloride permeability, of concrete mixes that included varied amounts of fly ash and quarry dust. The findings demonstrate that reducing waste by recycling stone dust to pavement is a feasible alternative.
