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.
Highlights
Fly ash (F.A) particles typically solidify while they are still in suspension in exhaust gases and are generally spherical in shape
Municipal solid waste incineration (MSWI) ash is used in part as raw materials for cement clinker production by taking advantage of the high contents of SiO2, Al2O3, and CaO
The present study investigates about the potential use of fly ash based bricks and tiles as construction material resulting in either full or partial replacement of clay bricks and tiles
Summary
Fly ash (F.A) particles typically solidify while they are still in suspension in exhaust gases and are generally spherical in shape. The traditional construction materials such as concrete, bricks, hollow blocks, solid blocks, pavement blocks and tiles are being produced from the existing natural resources. The present study investigates about the potential use of fly ash based bricks and tiles as construction material resulting in either full or partial replacement of clay bricks and tiles. The procedures used in the chemical analysis of fly ash to determine the oxides of silica, aluminum, iron, calcium, magnesium, total sodium and total potassium is as follows heat the sample prior to fusing as indicated for material previously ashed in ASTM Designation: D 4326. The chemical composition of T.F.A and R.S.D particles and the element distribution over the sample surface was determined by EDS. The Quantitative results from point analysis of T.F.A and R.S.D are being used in the study are shown in Figure. and Figure.
