Study of Partial Replacement of Cement Using Cow Dung Ash and Marble Dust Combination and Sand Using Glass Powder for M25 Grade of Concrete

Abstract

Abstract: The use of cement in concrete industries increasing day by day. Concrete is the most popularly used construction material in civil engineering industry because of its high structural strength, stability and durable. The most important part of concrete is the cement, fine aggregate, and coarse aggregate. In this modern era, many new technologies of construction materials are introduced. Growth of population, urbanization and industrialization has increased the requirement of cement. The production of cement leads to environmental issues due to release of gaseous pollutants. Cement manufacturing industry is one of the CO2 emitting sources besides deforestation and burning of fossil fuels. The global warming is caused by the ejection of greenhouse gases, such as CO2, to the atmosphere. Among the greenhouse gases, CO2 contributes about 65% of global warming. The global cement industry contributes about 7% of greenhouse gas emission to the earth’s atmosphere. The study for the use of Cow Dung Ash (CDA) and marble dust as partial replacement in production of concrete. The experiments were designed to study the effects of adding Cow Dung Ash (CDA) and marble dust in various percentages by weight 5%, 10%, 15% and 20% for M-25 grade of concrete and cure for the periods of 7, 14, and 28, days respectively before testing for the Compressive strengths.
