Effect of manufactured sand on self compacting concrete with industrial waste

Abstract

Concrete is a versatile construction material of this century. Concrete has several problems as a result of bad construction procedures and poor constituents in the concrete mix, but it is nevertheless a commonly used material. Poor compaction during construction is the primary cause of concrete deterioration. Honeycomb formations are the result of inadequately compacted concrete. This difficulty is solved with Self-Compacting Concrete (SCC) constructions since no external compaction or vibration is required. The labour required for compaction is also minimised by the development of SCC. SCC is one of the special concrete. It can compact by itself under the action of gravity or by its self-weight without vibration, bleeding, and segregation. newlineA large amount of industrial waste has been generated as a result of industrialization. Wastes are produced as a result of a variety of industrial activities. They have a wide range of properties and chemical compositions, and they have an impact on human health and the environment. As a result, waste management and disposal must be done safely in order to preserve a sustainable environment. The cement industry consumes much amount of the natural resources for the production of cement, in addition pollutes the atmosphere with the emission of CO2. Hence the waste materials from the industries, having pozzolonic nature can be used along with cement. Because of the rising shortage of river sand and natural aggregates across the country, the construction sector in India is under immense pressure to find alternatives for basic construction materials in order to fulfil the growing demand for infrastructure. Sand mining in rivers has been prohibited in several parts of our country due to its negative environmental impact. newlineIn this work newline
