Micro-structural Analysis of Fly Ash and Clay Compacts
Abstract: Industrial waste like fly-ash is mainly used as a good building material due to its low weight. But the main disadvantage of these bricks is its low compressive strength. So, a lot of research is going on to increase the strength of these bricks. Normal clay is used for making of bricks in a cheaper sense. So, a research is carried out to develop a new systematic procedure to produce …
