Influence of limestone waste as partial replacement
#0183;#32;Compressive strength test results of normal concrete with LSW with different replacement percentages are presented in Table 5 and Fig. 2 for, 25, 50, and 75%, respectively. Using LSW with levels 25% and 50% increased compressive strength of normal concrete about (6%, 13%, 8%) 25, (10%, 12%, 11%) 50 at 7, 28 and 90 days respectively, as compared with the normal concrete N350 .
