Abstract :
In this research for viscosity modifying agent in place of an expensive admixture, the usage of bagasse ash is assessed. Super Plasticizer values are kept constant and Bagasse ash is added in different proportions and a study is carried out on its hardened and fresh properties. Results indicated to the possibility of utilizing bagasse ash to develop an economical SCC. Different mixes of concrete (including Control Concrete and Blended mixes) displayed the slump flow values in the range of 313 mm to 675 mm, L-box ratio from 0.9 to 0.8 and flow time from 1.4 seconds to no flow were obtained for the fresh state of concrete. Two mixes out of five met the requirements recommended by the European guide lines for making self-compacting concrete (EFNARC). Self-compacting blended mixes of bagasse ash at 28 and 56 days showed comparable results with control concrete with a cost reduction of 43.23%. The outcomes of this research will positively affect the commercial construction scenario of Pakistan and bring economical and environmental safety benefits as bagasse ash is locally available free of cost, which is wasted in millions of tons every year without any usage in construction.
