An Experimental Investigation on Partial Replacement of Sand with Bottom Ash with and without Superplastisizer

T. Purushotham Reddy, Dr. K. Rajasekhar

Abstract: Sustainability is one of the major themes of the future in our society. The construction industry alone is making use of millions of tones of natural river sand every year, which creates environmental imbalance (depletion of water table etc. ). Hence, it is the time to go which consist of alternative materials (marginal materials or mineral admixtures) which can replace sand effectively, The various physical properties and mechanical strength properties studied consist of compressive strength, splitting tensile strength. And also durability properties studied consist of calorimetric chlorination technique. Similarly, to investigate the effect of use of bottom ash as partial replacement of fine aggregate using with super plasticizer at various percentages i. e. , 10 %, 20 % and 30 % on concrete properties such as compressive strength, split tensile strength test and also durability test. Compressive strength of bottom ash concrete at the curing age of 28 days was almost adequate to the normal concrete. Splitting tensile strength of concrete improved at percentages of replacement of bottom ash.
