Impact of fly ash and bagasse ash on durability performance of lightweight concrete with the experimental study

Abstract

Lightweight concrete [LWC] is rapidly reaching its full potential for a broad range of applications in the construction of concrete structures. It is tailor-made material for specific applications having beneficial properties. Therefore, the paper is devoted to the experimental analysis and study of fly ash and bagasse ash on the durability properties of lightweight concrete. Durability can be defined as the ability of the material to withstand the effects of its environment which are influencing the deterioration of concrete. The saturated water absorption and sorptivity was studied through experimental investigations, by varying the percentage of fly ash and bagasse ash content. Both fly ash and bagasse ash shows that the increase in the percentage of replacement leads to the more absorption of lightweight concrete. The results are investigated and presented on the studies conducted as follows, showing that the increases in the percentage of replacement, strength also increased.
