Mechanical properties of geopolymer concrete containing fine recycled granite aggregates.
Keywords:
geopolymer, concrete, granite, recycled aggregateAbstract
The aim of this study is to investigate the mechanical properties of geopolymer concrete containing fine recycled aggregates. Granite industry waste was used to replace natural sand at dosage levels of 0%, 25%, 50%, and 100% by mass of fine aggregate. The results were compared with the control concrete made with fine natural aggregates. The results showed that the use of recycled granite aggregates increased the 7-day compressive strength of concrete. The flexural strength increased with the increase in granite aggregate content. In addition, geopolymer concrete containing 50% granite aggregate showed the highest toughness value.
