Abstract

There are several years that concrete has exhibited particular roles as most consuming materials among civil engineers. Through these years, several factors in concrete have been studied. Durability of concrete is one of these factors that affect the service life of concrete structures. Recently, the properties of Rice Husk Ash (RHA) as high-quality artificial pozzolanic materials are important issues that specialists are concerned with, especially in East Asia and North America. It is not widely produced and used due to lack of adequate experiments on this material. In this research, in order to supply typical RHA, for the first time in the Middle East, an special furnace was designed and constructed in Amirkabir University of Technology. This furnace was built in a pilot size having the ability to control the conditions of combustion. Then various experiments were carried out to determine mechanical properties and durability of concretes incorporating RHA. The results show that RHA as an artificial pozzolanic material has increased the strength and durability of concretes.
