It is found that the gain in compressive strengths of M-2 concrete over M-1, M-3 over M-1 and M-3 over M-2 concrete is in the range of 9–22, 19–24, 2–12%, respectively, upto 90 days of tap water curing. The gain in strength of M-sand mixed concrete may be due to its perfect grading and its cubical shape.
