Abstract:
Rapid growth in construction industries leads to consumed large amount of cement and sand, for save environment and natural resources of sand we need alternate of these materials. In study design concrete M35 grade mix ratio of (1:2.16:2.9)with combination of 10% wollastonite powder as cement replacement and partially replaced the natural river sand by granite fines in range of 0 to 50% in steps of 10% study their physical, mechanical and durability’s characteristic of mix,find that the workability is decrease for each mix, attained to required workability need a SP (ECMAS-HP-888) dosage, maximum strength in flexural and compression are observed at 7, 28daysfor 20% replacement GP in mix (W10G20) and further increase amount of replacement decrease in strength is observed. Maximum UPV observed at 20% granite fines replacement for 28 days is 4500m/sec. Depth of carbonation is observed minimum at 20% replacement for mix (W10G20) at 7, 28 days is 2.2mm and 4mm, maximum depth found for 50% replacement of GP by sand in mix (W10G50) is 4.9mm and 6.9mm for 7, 28 days.
