Performance of granulated foam glass aggregates in concrete
Granulated foam glass (GFG) aggregate has been receiving more and more attention as the solution to help recycle glass and reduce mining for aggregate for concrete. The purpose of granulated foam glass is to be used as a substitution for natural aggregate during the concrete-making process. The aggregate has a much lower density than natural aggregate, which help reduce the dead load of the concrete but will also reduce its mechanical properties. This study aims to produce knowledge on how concrete’s material properties vary when different amounts of GFG are used in concrete to replace natural sand and stones. Natural aggregates are substituted by GFG based on the volume. Five different groups of specimens with substitutions of 0%, 10%, 20%, 30%, and 50% are made and tested for compressive and tensile strength. Moreover, because of how lighter particle float to the top when vibrating, this study also investigated how the aggregate behaves with different compaction methods used. The result of the compressive and tensile strength shows a decrease in strength proportionate with the increase in the amount of granulated foam glass aggregate substituted in. The density of the hardened concrete was reduced by about 20% at 50% substitution. Of the four methods used in the compaction process, the aggregate is best distributed when using the vibrating rod to compact every 100mm of the cast specimen.
