Conventional Concrete and Fine Glass Reinforced Concrete (Glascrete): A Study on Strength Gain and Mechanical Properties of Different Curing Periods

Abstract

Glass is a common waste generated in our everyday life. Incorporating fine glass as a complete
replacement in fine aggregate in a concrete mixture helps to promote sustainable construction.
This experimental study investigated the effects of curing periods on strength gain in
conventional concrete and glasscrete if it extends up to 35 days of curing period. Eighteen (18)
concrete samples of rectangular prisms and eighteen (18) samples of cylindrical specimens were
tested using the universal testing machine. The result showed that the compressive and flexural
strength of glasscrete declines due to the alkali-silica reaction when it is cured in less than 28
days. In terms of workability, concrete with glass shows a lower slump than in conventional
concrete, which means that the workability of concrete decreases if it is incorporated with
glass.
