Paper Title
Assessment of Improvement in Properties of M-45 Grade Concrete by Using Partial Replacement of Cement with Fly Ash and Coconut Shell Ash
  D sandhya kumari,  Dr.Ch.Bhavannarayana,  Dr.V.Ganapathi Rao

The environmental impact of Cement is significant because its production emits large amount of carbon dioxide. Utilization of industrial solid waste or secondary materials has been encouraged in construction field for the production of cement and concrete because it contributes for reducing the consumption of natural raw materials as resources. The volume of wastes generated in the world has increased over the years due to increase in population, socioeconomic activities and social development. One of the most attractive options of managing such wastes is to look into the possibility of waste minimization and re-use. The cost of cement used in concrete works is on the increase and unaffordable, yet the need for housing and other constructions requiring this material keeps growing with increasing population, thus the need to find alternative binding materials that can be used solely or in partial replacement of cement. The effect of coconut shell ash and fly ash has been investigated and the experiments have been done to utilize these waste materials with concrete. Agricultural waste material, in this case, coconut shells ash which is an environmental pollutant and Fly ash a waste generated by thermal power plants is as such a big environmental concern are used as a partial replacement of cement in concrete. The objective of this experimental study is to investigate the use of fly ash and coconut shell ash as partial replacement of cement for M-45 Grade concrete. The replacement levels of cement are 20%, 20%, 20% of fly ash and 10%, 15%, 20% of coconut shell ash. Compressive strength, Split tensile strength and Flexural strength are evaluated at 3,7and 28 days. This project evaluates how different contents of fly ash and coconut shell ash added to concrete may influence the concrete properties.

Keywords- Coconut shell ash, Fly ash, Compressive Strength, Split Tensile strength and Flexural Strength.
