The main aim of this project is to study the effectiveness of surface pre-treatment by Ultraviolet (UV) light and Ultrasonic treatment as a replacement for the natural aggregate in concrete mixtures on the rubberised concrete properties. A handful of studies have been conducted to find effective concentrations of rubber aggregates to be used in concrete mixes; however, a literature gap exists in the study of a replacement for the coarse aggregates. Hence, this study analyses the effect of surface pre-treatment on the mechanical properties of the optimal rubberised concretes. The objectives of the project are:
• To determine the effects of substituting the natural aggregate with rubber aggregate on the concrete properties (density, compressive and tensile splitting strength, elastic modulus)
• To estimate the optimum amount of rubber aggregates to be used in concrete mixes for civil engineering applications.
• To employ a sustainable and easy to execute type of pre-treatment and compare its performance against other pre-treatments previously researched
• To analyse the effect of surface pre-treatment using UV light and Ultrasonic treatments on the mechanical properties of the crumb rubber aggregates.
• To recommend methods for future research on the rubber aggregate replacement in concrete as a substitute for natural aggregate
