Abstract - In this project the comparative study of Self Healing and Ductile Concrete Mix Designs by using Silica Fume With the conventional concrete mix design , As the cement production increases in the content of carbon dioxide in atmosphere which causes air pollution and harm the nature and due to which global warming and climatic change occurs in atmosphere. therefore by replacing cement content with silica fume in concrete mix design somehow prevent the atmosphere therefore in this project the cement content is replaced by silica fume by varying percentage and the comparative analysis of conventional concrete with concrete mixed with silica fume is done and observed that when we added 15% of silica fume to total weight of cement, there is a increased in compression and hence the tensile strength increases and therefore ductility of concrete also increases and the cracks are reduced in concrete. From this work concluded that, High strength of concrete can be achieved by adding silica fume concrete. The repairing ability of the concrete is in the silica fume concrete. Silica fume filled the voids in concrete and cracks in concrete are quickly healed.

Key Words:  Concrete mix design, Workability test, Normal Consistency Test and Compressive Strength test
