A Study on properties of Compressive strength, Sorptivity, Acid resistance and Alkalinity on M25 Grade of concrete

摘要

Fly ash is used as fine granulates becomes suitable for partially obstructing voids in addition to pores .At later ages, the concrete mix which is replaced with fly ash exhibit greater strength development than control mix as the relative strength continues to increase with curing times. There is a significant reduction in comparative strength, with greater and consistent reduction at higher replacement levels of fly ash content. There is a important reduction in relative strength, with greater and consistent reduction at higher replacement levels of fly ash content. At later ages, the concrete mix replaced with fly ash leads to decrease in coulombs charge passed, due to higher amount of pozzolano and proper particle size distribution resulting in lower permeability. The permeability is an....
