Property Research of Concrete Mixed with Flyash

Abstract:

Flyash is the ash collected from chimney of coal-fired power plant. According to statistics, 70% of coal production in our country is used for thermal power generation. One ton of flyash would be produced as long as power plant uses 4 tons of coal. Annual emission of flyash has surpassed 100 million tons. It is predicted that it may be 150 to 260 million tons per year up until Year 2000 to Year 2013. Huge number of emission of flyash covers a mass of farmlands and water resources. Ash disposal area of thermal power plant cannot afford the increasing number of flyash and its storage capacity is in an emergency in which ash disposal area is being extended or newly constructed with a massive amount of money. Therefore effective, universal and vast use of flyash is of profound significance for reducing the environment load and saving limited construction fund. This paper researches the beneficial effects of flyash on concrete property.
