Cylindrical specimens were casted by using cement (high early strength), sand and limestone powder for water to cement ratio (W/C) of 100, 130, 150, 170 and 190 %, cement to sand ratio (C/S) of 30%, limestone powder to cement ratio (L/C) of 130% by weight, and their softening behavior was investigated. The influences of material strength on compression fracture zone length and tensile fracture energy are investigated. Results have indicated that compressive strength of cement treated sand is independent of the size of the test specimen and variation in fracture energy is observed.
