Abstract:
The mechanical and durability performance of both recycled plastic‐rubber modified and tire steel fiber‐reinforced plastic‐rubber modified mortar samples will be evaluated with sample mixture design and lab tests. Recycled plastic‐rubber aggregates, with mesh sizes from #10 to #18 partially replaced the fine aggregates with three volume percentages 10%, 15%, and 20%. Control mortar, mortar with recycled plastic‐rubber and mortar with tire steel fiber reinforcement and recycled plastic‐rubber were prepared. The compressive and indirect tensile strength were measured and compared. The fracture strength and fracture energy were measured with the single‐edge notched beam test to evaluate the effects of recycled plastic‐rubber aggregates and tire steel fibers. The drying shrinkage and permeability tests were conducted to evaluate the durability performance of these sample types. These results will demonstrate the utilization of tire steel fiber and recycled plastic‐rubber to improve the mechanical and durability performance of cement mortar.
