Effect of Pulverized Glass Powder on the Compressive Strength of Revibrated Concrete

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.
