Abstract
Experimental study on the Effect of pulverized glass powder (PGP) on the compressive strength of revibrated concrete is presented. A concrete mix of 1:2:4 was used to prepare a total of forty-eight fresh concrete cubes specimen: sixteen for control with 0% PGP; thirty-two cubes for the different percentages of OPC replacements (10%, 20%, 30% and 40% PGP). Each set of fresh concrete cubes were subjected to initial vibration and then re-vibrated at an interval of 10 minutes successions up till 1 hour. The compressive strength was determined at 7 and 28days curing age for each concrete cube. The results show that maximum compressive strength were best achieved in three categories: 21.39 N/mm2 for nonrevibrated; 23.64 N/mm2 and 18.34N/mm2 for 0% and 20% PGP revibrated concrete respectively. It is concluded that pulverized glass can be blended with cement up to 20% PGP to achieve a substantial compressive strength of revibrated concrete.
