Study on properties of fly ash bricks with partial replacement of waste materials and structural performance of masonry walls

Abstract

In the construction history, brick is evergreen and unavoidable newlineconstruction material. From the ancient time to till date, of sun-dried mudbrick newlineto conventional fired clay brick, brick production is an art that follows a newlinevariety of making procedures using different kinds of ingredients. However, newlinethe current brick industry involves higher polluting technologies. It causes newlineenvironmental degradation due to several factors, including constant newlineexcavation of topsoil, kiln firing, shortage of natural sand for quality brick newlineproduction due to continued mining. In the current situation, brick production newlineis not an eco-friendly activity and leads to unsustainable development. With newlinethe available engineering science, either the change in a manufacturing newlineprocess or alteration in raw materials is the ideal solution. Thus, an newlineenhancement in brick manufacturing is essential and need further research newlineand development.Fly ash, a waste material obtained from the thermal power plant, is newlinerecognized as a supplementary cementitious material in construction. newlineCurrently, the use of fly ash in brick manufacturing is mandatory as per the newlinegovernment ordinance. Fly ash-based bricks are the promising material for newlinefuture as it is less-energy intensive and offers environmental-friendly newlineprotection because it releases no pollutants while making bricks. Currently, newlinedue to vast application in different areas of construction, fly ash is not an newlineabundantly available material, listed in one of the scarce resources. To cater newlineto the country s brick requirements point of view, an alternate for fly ash with newlinesimilar technological benefits is essential. Also, the use of natural sand in newlinequality brick production is an option nowadays due to the non-availability newlineand economic concerns. Stone dust, a waste material from cutting process of newlineaggregate, is used in the brick production. The quality and quantity of stone newlinedust are varying and depend on the availability of parent rock. Hence, an newlinealternate for fine aggregate is also essential. The exchange of potential waste newlinem
