Preparation and Creation of Interlocking Concrete Block Bricks by Using Tempered Glass Leftovers

In this research, the compressive strength of interlocking concrete blocks made using 80% glass instead of sand will be compared to the TIS 58-2533 standard. The blocks have dimensions of 10 cm in width × 25 cm in length and 12.5 cm in thickness. Additionally, there are two circular holes beneath the block that measure 5 cm in diameter and 1 cm deep. These holes were placed at different distances based on the thickness of the interlocking concrete block. This was achieved by using concrete with a 1:1.17:1.59 ratio and a water/cement value of 0.40 (w/c) for each block. Thirty samples of each kind, totalling 60 samples, were air-cured and moist-cured for 3, 7, 14, 21, and 28 days using a glass mixture instead of sand. The findings demonstrate that when 80% glass is used as a substitute for sand in a 1:1.17:1.59 ratio with a water/cement ratio of 0.40 (w/c), the interlocking concrete blocks exhibit a consistent interlock and curing for the entire 28-day duration. The average ultimate strength was 133.65 kg/cm2, which is 81.29% higher than the TIS 58-2533 standard for moist curing throughout the 28-day period. The average ultimate strength was 148.20 kg/cm2, which is higher than the TIS 58-2533 standard by 83.13%, and the moisture curing experiment exceeded 9.82%.
