| Summary: | Prosopis Juliflora (seemai karuvelam in Tamil) is a kind of tree which can draw water from deeper layers of the ground due to its deep penetrating roots and also absorbs atmospheric moisture heavily. Recently Tamilnadu government has planned to remove the tree with the help of PWD. Sugarcane bagasse is a dry pulpy fibrous substance that remains after crushing and extracting juice. This project deals with the view of partial replacement of cement by Prosopis Juliflora ash and addition of sugarcane bagasse as fibre. Utilization of Juliflora ash as a partial replacement for cement is one of the methods to increase the strength of concrete. Sugarcane bagasse increases crack control and ductility. The proportions for trial concrete are 5% and 10% Prosopis Juliflora ash as replacement for cement and 0.5% and 1% for sugarcane bagasse as fibre. The strength characteristics such as compression strength, flexural strength and split tensile strength are carried out on 7th, 14th and 28th day after curing and compared with conventional concrete. It is found that there is a considerable increase in the compression strength, tensile strength and flexural strength of the concrete. The use of Prosopis Juliflora ash and Sugarcane bagasse fiber is both environmentally and economically beneficial. Thus, leading to a sustainable relationship.
