Title

Study on Suitability of Fly Ash To Be Used as pozzolana in Concrete.

Abstract

Fly ash is most commonly used in the manufacturing of Portland Pozzolana Cement (PPC) in concrete applications. Fly ash utilization, especially in concrete, has significant environmental benefits. The use of fly ash in partial replacement of Ordinary Portland Cement (OPC) has many benefits and improves concrete performance in both the fresh and hardened state. Fly ash use in concrete improves the workability of plastic concrete, and the strength and durability of hardened concrete. The reduction in heat of hydration, reduce permeability, resistance against aggressive environment are few added advantages with fly ash application in concrete. Due to its abundance availability and associated disposal problem, the researcher tried to characterized fly ash for different application in green concreting. The physical and chemical characteristics of fly ash vary among combustion methods, coal source, and particle shape. Currently, over 20 million metric tons (22 million tons) of fly ash are used annually in a variety of engineering applications. Typical highway engineering applications include: portland cement concrete (PCC), soil and road base stabilization, flowable fills, grouts, structural fill and asphalt filler. Quality requirements for fly ash vary depending on the intended use. Fly ash quality is affected by fuel characteristics (coal), coal firing of fuels (bituminous and sub-bituminous coals), and various aspects of the combustion and flue gas cleaning/collection processes. The four most relevant characteristics of fly ash for use in concrete are loss on ignition (LOI), fineness, chemical composition and uniformity. In the present paper , the fly ash from NTPC power plant of India is tested for its suitability to be use as pozzolana in concrete applications.

Key Words
