Abstract
Hydro-abrasive resistance and mechanical properties of rubberized concrete
Highlights
Large quantities of waste materials or industrial by-products are presently used thanks to recent advancements in concrete technology
The use of recycled rubber in the production of concrete is important for two reasons: direct use of waste material is important for environmental reasons while enhancement of physico-mechanical properties of concrete is important for structural reasons
The concrete used for construction of hydraulic structures, which is in direct contact with water, apart from having good mechanical properties, must be resistant to hydro-abrasion
Summary
Large quantities of waste materials or industrial by-products are presently used thanks to recent advancements in concrete technology. In their research [9], Lakusic, Bjegovic et al used recycled rubber in order to improve mechanical properties and durability of an innovative and environmentally acceptable material for the production of contemporary railways on hard concrete base They replaced 5 percent of stone aggregate with the recycled granulated rubber and improved in this way the modulus of elasticity, water permeability, and capillary absorption of concrete, while reducing diffusion of chloride through concrete. In his paper [28], Šušterčič showed that the concrete with 9.5 percent replacement granulated rubber instead of fine river aggregate, has a better hydro-abrasive strength in comparison with the reference concrete with no rubber. Effects of replacement of fine aggregate by the recycled granulated rubber on physicomechanical characteristics and hydro-abrasive resistance of concrete are studied in this paper
