Sustainable Fly Ash Based Roof Tiles with Waste Polythene Fibre: An Experimental Study

Abstract

The compressive stress-strain behavior and other characteristics of treated fly ash based roof tiles have been studied by several experimental tests. This paper attempts to presents the results and observations of a study and comparison based on the past reported experimental data. Based on the results and observations of the comprehensive experimental study, five "control points" have been identified. The new sets of experiment have been carried out to investigate whether it might be possible the use of fly ash in fly ash based roof tiles for residential construction. In the present study, treated fly ash (TFA) of C category was used with different materials as a replacement of clay for making treated fly ash stone dust roof tiles (TFASDRT). Treated fly ash stone dust roof tiles (TFASDRT) were studied at varying percentages of cement, coarse sand, and radish stone dust (RSD) along with the constant percentage of waste polythene fibre (WPF). A research program was undertaken to evaluate the suitability of such test for assessing the properties of treated fly ash stone dust roof tiles (TFASDRT). The result of this study recommends that the fly ash based roof tiles provides a sustainable supplement to the traditional clay roof tiles, they increase the efficiency of traditional roof tiles and significantly help to reduce the environmental issues associated with the disposal of these waste materials.

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

“…The highest compressive strength reached (6.896 MPa) for the combination of 15TFASDBT. In other study was carried out on fly ash based roof tiles with waste polythene fibres [8]. The compressive strength has been increased by 30.65% compared to the past study carried out by [7].…”

“…Weak mortar was found to be very weak and soft as compared to other three i.e., intermediate, strong and very strong. Intermediate mortar perform stable as compared to weak and strength increased about (29.41%), then Strong mortar performed well in terms of strength and ductility as compared to other two, strong mortars was found (51.40%), higher than intermediate mortar, in comparison of strong mortar very strong mortar was reached the highest strength about (29.08%) more than the strong [8]. The spherical shaped particles of fly ash act as miniature ball bearings within the concrete mix,thus providing a lubricant effects.…”

“…3.The compressive strength [8], has been increased by 30.65% compared to the past study carried out by [7]. 4.Addition of waste Polythene Fibre (W.P.F) provides more strength in the tiles as compared to the other past studies refer ( Figure. 11 Typical failure modes).…”

“…A comparison of stress-stain curves generated by the TFASDRT and SCBT obtained in the present experimental study is shown in Figure. 9(b), which show a very close match between the TFASDRT and SCBT curves [8]. The stress strain curves of different test series of FAB, FRFAB, FALB, FRFALB, FALSDB and FRFALSDB have been plotted and shown in Figure 10 [6] .…”

“…The tiles were found to be behaving linearly up to about onethird of the ultimate failure load after that the behavior became highly nonlinear. An average stress-strain curve for all the tiles types used in the study is also shown in Figure. 8 [8]. The stress-strain curves for fly ash based tiles for six grades of mould obtained by averaging the data from ten specimens of each grade.…”
