Now days the construction industry in the India is facing one of the major problem that is natural fine aggregate. And court awarded that totally band on excavation of fine aggregate from river because they affect on environment and changing the river direction. (fig.5). Thus the more natural fine aggregate are highly needed to replace with artificial fine aggregate. This paper presentation the study of crack pattern of concrete slab, each size is (500*300*50) mm and replacement of natural fine aggregate with artificial fine aggregate by 20%,40% 60% 100% and also finding the compressive Strength of that concrete cube. And these experiment is carried out maintain temperature 32 0cAnd the according to experimental result show that the replacement of natural sand by artificial sand up to 60% and gives best result that is maximum strength and minimum area of crack.
Key words: - Concrete slab, natural fine aggregate, artificial fine aggregate (grit), crack pattern.
