Evaluating The Strength Gain And Structural Properties Of Self-Compacting Concrete By Incorporating Robo Sand And GGBS

Self-compacting concrete is identified as “highly flow able” and stable<br>concrete that can spread readily into place and fill the formwork without<br>any vibration and without undergoing any significant segregation. The<br>design of concrete mix is not a simple task on account of widely varying<br>properties of the constituent materials and many factors affect its target<br>value. The mix design problem is a multi-characteristic optimization<br>problem. However, in the present work, the problem is considered to the<br>single characteristic optimization problem and the characteristic to be<br>optimized strength of concrete. In the present paper, Okamora technique<br>has been applied to obtain optimum of SCC mix design to get the<br>mechanical and structural strength of concrete and cement is replaced<br>by GGBS and fine aggregate is replaced by Robo sand and the<br>experimentation work includes the fresh properties tests on SCC to know<br>the characteristic behaviour and the hardened properties of SCC is<br>determined to know the compression strength, split tensile strength,<br>flexural strength of beams and durability properties.
