• Required volume of Mortar = 10 x 0.015 = 0.15 m3
• We find out the volume of mortar in wet condition mortar volume 0.15 m3 (After the consolidation of Cement+sand+water).
• So the dry volume = 0.15+(0.15 x 35%) + (0.15 x 20%) = 0.2325 m3

Calculate the compressive strength of each core by dividing the maximum load by the cross-sectional area, calculated from the average diameter. Express the results to the nearest 0.5 N/mm2.
