Development of Fly Ash Bricks through different Technologies and a Comparative Study of their Compressive Strength

Abstract

Construction materials are critical to the development of infrastructure and with the ever increasing population and deteriorating environmental conditions, need for new materials which are energy efficient and environment-friendly is on the rise. Fly ash comprises of the fine particulate matter that rise with the flue gases from combustion of carbonaceous matter, typically coal [1]. It is one of the major waste products of the thermal power plants. It is categorized mainly into two categories according to ASTM C618 standards as follows:  Class F fly ash : Fly ash having lime(CaO) content less than 20% by weight  Class C fly ash : Fly ash having lime(CaO) content more than 20% by weight
