This review paper presents the influence of cow dung ash as partial replacement of cement material in production of concrete. In this modern era, many new technologies of construction materials are introduced. Growing population, urbanization and industrialization has increased the requirement of cement. The production of cement leads to environmental issues due to emission of gaseous pollutants. The availability of materials with good quality is less and also economically very high. So we need a material which is cheaper as well as ecofriendly for the environment like cow dung ash. These materials are partially replaced by cement. Many experiments by different researcher were done to study the effect of adding CDA in various percentage (0%, 5%, 10%, 15%, 20%, 25% and 30%) by the weight of cement. The curing period is of 7, 14 and 28 days respectively for the testing of compressive strength. The other mechanical properties like split tensile test, the durability properties like rapid chloride permeability test and water penetration test were to be conducted on M25 grade concrete. Thus the settling time is prolonged by adding the cow dung ash to the cement. The materials like cow dung and fly ash are of good quality, cheaper, ecofriendly and durable.
