Abstract
The development of sustainable products usually involves the use of energy-efficient recycled or local natural materials, thereby reducing the use of non-renewable resources and thus environmental impact. Rubberized concrete is a form of concrete that uses discarded tire rubber particles instead of natural aggregates. This type of concrete offers an environmentally friendly alternative to the millions of discarded tires. In this research, crumb rubber (CR) will be used as a full or partial replacement for fine and coarse aggregates in concrete to improve impact energy absorption, abrasion resistance and freeze-thaw durability. The raw materials needed for cement production are non-renewable and are dwindling at a rapid pace. In addition, the production of 1.0 tonne of Portland cement releases about 0.75 tonnes of CO2 emissions. Extensive research is being conducted to evaluate the feasibility of using industrial waste as a complete substitute for ordinary Portland cement (OPC) to produce better binders. One such successful experiment is geopolymer concrete. Geopolymer belongs to a new generation of low-carbon binders formed primarily by alkali activation of waste aluminosilicate materials. Geopolymer concrete is a type of concrete made from industrial waste such as fly ash, slag and silica fume. It has several advantages over conventional Portland cement concrete, including higher strength and durability, lower carbon emission and better resistance to chemical attack. In this study, the rubberized geopolymer concrete with the rubber content (i.e. 10% by volume) and three different rubber aggregates with nominal sizes of 2 mm (1-3 mm), 5 mm (2-5 mm) and 10 mm (5-10 mm) are processed to produce rubberized geopolymer concrete and investigate behavior under static and dynamic loading.
