Abstract

Fillers with their varied size and shape interact with cement in several ways giving concrete other properties. In this study quartz and limestone fillers of same size (200 micron) was replaced with cement to see if loss of strength occurs. Eight sets of concrete was prepared to do the various comparisons. One set of concrete was designed as a normal concrete, another set as a normal Self compacting concrete having fly ash and silica fume in a certain percentage. Keeping fly ash and silica fume percentage constant the other six sets of concrete was produced having varied percentage of quartz and limestone fillers. The result is positive,cement replacement by quartz and limestone fillers upto 30% do not show much loss in trength and gives the designed target strength. Strength retention ability of a concrete after exposure to high temperature is of great importance in terms of its stability. These sets of concretes were then exposed to elevated temperature at 3000C, 4500C and 6000C with a retention period of one hour. Their residual strength, weight loss and surface characteristics is observed.
