Abstract:

This study aims to experimentally investigate the fresh and hardened state properties of roller-compacted concrete (RCC) blended with microsilica and study the functional relationship between concrete constituents and the curing ages. To measure the contribution of microsilica to the hardened state properties, microsilica was used to replace cement with ratios of 10%, 15%, and 20% at varying water to cement ratios of (0.35, 0.40, 0.45, 0.5). A control mix (0% micro-silica) content was prepared for each water-cement ratio, and these were used for comparison. A concrete mix design was carried out using ACI 211 standard code procedure for RCC.
A total of one hundred and forty-four cubes were tested to obtain the compressive strength, and the compressive strength was at the maximum value of 64.89 at a water-cement ratio of 0.35, and 15% replacement of cement with micro-silica.

Keywords:

Roller Compacted Concrete, Microsilica, water to cement ratios.
