Feasibility of coal fly ash based bricks and roof tiles as construction materials: a review

Abstract

Abstract. The aim of present study is to investigate about the potential use of coal fly ash along with other natural and solid wastes for the production of coal fly ash based bricks and roof tiles. The study is based on the comprehensive reviews available from the previous experimental data on coal fly ash based bricks and roof tiles. The study intendeds to provide the essential technical information and data for the use of fly ash mix with other solid wastes and reveal their suitability as construction materials. It has been found that samples were non-hazardous in nature and vigorously used as an additional construction materials and their compositions are perfectly fit to make the strong composite material for bricks and tiles. The three past studies have been demonstrated that, fly ash based bricks and roof tiles provides a sustainable supplement to the traditional clay bricks and roof tiles, that not only increases the efficiency of traditional bricks and roof tiles but also helps significantly to reduce the environmental issues associated with the disposal of these waste materials. In addition to this study highlights the potential use of fly ash for producing sustainable construction materials.

Evaluating Recycled PET as an Alternative Material for the Construction Sector Towards Sustainability

“…It primarily focuses on strategies for effectively utilizing suitable waste materials to enhance sustainability and the economy by emphasizing recycling and reutilization [8][9][10][11]. Within the construction industry, materials frequently recycled comprise crumb rubber, silica fumes, roofing shingles, palm fruit husks, citrus rinds, kiln dust cement, asphalt, flyash, foundry sand, glass, slag, and recycled aggregates derived from dismantled concrete infrastructures [12][13][14][15]. For this review article, PET waste as a substitute for natural construction material is selected for systematic review.…”

Enhancing Sustainability and Economics of Concrete Production through Silica Fume: A Systematic Review

“…The consequences of rapid economic growth led by the Industrial Revolution have raised CO 2 emissions on a colossal scale [7][8][9][10]. CO2 emissions have increased to 386 ppm, exceeding natural limits since the beginning of the 21 st century due to world urbanization [11][12][13][14].…”

Influence of Unburned Carbon on Environmental-Technical Behaviour of Coal Fly Ash Fired Clay Bricks

“…These limitations in the recovery of ashes in the manufacture of concrete reinforce the need for a more rigorous study of its recovery in other industrial processes, specifically in the ceramic industry. Many studies have investigated the properties of clay-based bricks containing CFA to evaluate the technical performance of FCBs [9,17,[28][29][30][31][32][33]. Specifically, the study of the percentage of unburned in CFA on the final properties of FCBs, only Vasic et al [34] considered it as an input parameter in an artificial neural network model.…”
