Abstract:
Sustainable development in concrete industries is reducing the cement consumption in overall the world. Huge amount of carbon dioxide gas is released to the atmosphere during the production time of Portland cement. Carbon Dioxide is the leading contributor for the greenhouse effect and it directs to the global warming of world. In the present situation, most of the developed countries are thinking about these issues and implement severe rules and regulations to limit of the carbon dioxide emissions. So supplementary cementitious materials are required to reduce the consumption of Portland cement for the sustainable development. Fly Ash is one of the most abundant supplementary cementitious materials in worldwide. It is a by-product and waste material in thermal power stations. Disposal of fly ash is one of the major problems in the power stations because it leads to many environmental issues. Utilization of Fly Ash in the concrete industries, assure sustainable development by reducing cement consumption and also reduce the emission of carbon dioxide to the environment. The superior properties of fly ash provide much support to improve the rheological properties of fresh concrete and produce ultimate strength as well as better durability in long term hardened concrete. From the broad view it can be ensured that the usage of High-Volume Fly Ash is an environmentally friendly process and also it will enhance the quality of concrete such as high-performance concrete.
