EXPLORING HIGH STRENGTH CONCRETE WITH PARTIAL CEMENT REPLACEMENT BY FLY ASH AND SAND SUBSTITUTION WITH STONE DUST: AN EXPERIMENTAL INVESTIGATION

Abstract

Since cement, a substance that generates a 
lot of carbon dioxide, makes up the bulk of concrete, 
it has a significant environmental impact. By 
reducing the amount of cement used as much as 
feasible by the inclusion of mineral additives like fly 
ash, concrete building may be made with less of an 
environmental 
effect 
without 
compromising 
durability requirements. One of the most urgent 
environmental problems is the disposal of fly ash, 
which is created by power plants that burn coal for 
fuel. It is even more difficult to find a solution to this 
issue when fly ash production increases and landfill 
capacity decreases at the same time. This paper 
analyzes and discusses the fly ash admixed concrete 
study. Numerous research investigations have been 
carried out about fly ash concrete and its advantages. 
This research examines the mechanical qualities, 
durability metrics, and microstructural details of fly 
ash concrete both while it is new and after it has 
hardened. Furthermore included is a summary of the 
helpful fly ash concrete application case studies 
provided by the American Coal Ash Association.
