Impact on Strengthening Characteristics of Concrete Containing Pond Ash

Abstract

This paper details an experiment designed to assess the qualities of concrete made with pond ash. Ash is produced when coal is burned in a thermal power station to produce electricity. The ash that settles at the boiler's bottom is diluted with water and then dumped into a nearby pond. In order to make pond ash concrete, cement was substituted with pond ash at various percentages. 25, 35, and 45 percent were the respective replacement rates. Tests were conducted on the compressive strength, split tensile strength, and flexural strength of pond ash concrete at7,28,90,180, and 365 days. Early pond ash concrete had a slower rate of gain in compressive strength than later concrete. When the proportion of pond ash in concrete rises, its split tensile strength and flexural strength drop. Microscopical examination of pond ash concrete using a scanning electron microscope reveals a small reduction in the monolithic nature of C-S-H gel as pond ash content increases. X Ray Pond ash diffraction data shows the existence of quartz crystals in various amounts. By replacing sand with pond ash in concrete production, we may save money on materials, lessen our impact on the environment, and speed up the building process.
