Utilization of recycled tyre rubber waste as partial replacement of sand in ultra-high performance concrete (rubberized-UHPC)

Ultra-high performance concrete (UHPC) is a construction material with excellent mechanical properties and good durability as compared to conventional concrete. Despite its outstanding properties, UHPC also has some limitations in terms of cost and availability of raw constituent materials. UHPC req...

Civil engineering (General) Ultra-high performance concrete (UHPC) is a construction material with excellent mechanical properties and good durability as compared to conventional concrete. Despite its outstanding properties, UHPC also has some limitations in terms of cost and availability of raw constituent materials. UHPC require large amount of fine sand in the production of UHPC.

This idea also was inspired from the crucial environmental issues that resulting from the disposal of tyre rubber waste. It not only minimize the degradation, but it also guides to sustainable development by ensuring the conservation of natural sources. In this present study, the possibility of using RTRW as partial sand replacement was investigated. Four (4) different percentages of levels RTRW as partial sand replacement were prepared. There are 0 %, 5 %, 10 % and 15 % of RTRW from total weight of sand used. The UHPC and a series of rubberized-UHPC were labelled as plain-UHPC, rubberized-UHPC5, rubberized-UHPC10 and rubberized- UHPC15 respectively. RTRW consist of micromized rubber powder (MRP) and crumb rubber (CR). 10 % of silica fume was used as partial replacement of ordinary Portland cement (OPC). In this study, the strength properties of specimens in terms of compressive strength and splitting tensile strength at 7, 14 and 28 days were investigated. The experimental results revealed that the incorporation of RTRW into UHPC mix leads to the reduction of compressive strength and splitting tensile strength. It was found that increasing the percentages of RTRW as partial replacement of sand would decrease the strength in form of compressive strength and tensile strength.

Despite of this drawbacks, it was observed that rubberized-UHPC did not exhibit brittle failure meanwhile plain UHPC exhibited brittle failure.
