Fresh and Hardened Properties of Concrete Incorporating Recycled Glass as 100% Sand Replacement

This manuscript investigates the use of glass cullet as a 100% sand replacement in Portland cement concrete (glasscrete) systems. Specifically, it evaluates the fresh and hardened properties of these systems in comparison with conventional natural sand concretes on a basis of similar 28-day design compressive strength or the same w/cm. The results show that glasscrete mixtures need a lower w/cm to match 28-day compressive strength of conventional concrete. In addition, glasscrete mixtures have a greater elastic modulus, less drying shrinkage, less water sorptivity, and greater resistance against chloride ion penetration. Empirical curves are developed to provide material engineers and suppliers with necessary design specifications on the proper w/cm to implement when proportioning glasscrete mixtures. This study concludes that glasscrete mixtures can be produced with adequate consistency and mechanical and durability performance, as long as alkali-silicate reaction is properly controlled by using pozzolanic materials.
