Utilization of sewage sludge, oven slag and fly ash in clay brick production
Highlights This study consists of concerning bricks production made from various waste materials with different ratios. Semi-quantitative chemical analysis with (X-Ray Fluorescence) XRF and (Scanning Electron Micrograph) SEM results were included and discussed. Apprent porosity, water absorption, compressive strength, shrinkage, pressure strength, etc. subjects were examined and discussed. Reusing waste materials provides economic and environmental benefits to us. It is considered that such waste should be evaluated in the construction sector for environmental and human health and that such studies should be carried out.
Abstract It is intended in this study, evaluation of sewage sludge in construction sector. Sewage sludge (SS) is a serious problem in terms of environment and human health. When the past studies were examined about brick production, it was seen that the sewage sludge was used as a raw material in the production of brick. It is therefore thought that clay brick should be substituted with fly ash (FA) and oven slag (OS), which are also sources of environmental problems. Two different temperatures (900 °C and 1050 °C) were studied. Waste materials have been added to clay birck at rates of %5, %10, %15. 10 different mixtures with different proportions of waste materials were produced. Semi-quantitative chemical analysis (XRF), SEM analysis and atterberg limit experiments were has been performed on the materials used. Results of plasticity water, drying shrinkage, glow loss, water absorption, porosity, unit volume weight, density, compressive strength, thermal conductivity coefficient were determined for the sample were determined. SEM analysis was also has been applied to determine the microstructures of the samples. When examining SEM images of the raw materials, it was seen that SS is scattered, OS is spherical and FA is glassy and long molecular structure. In this study also determined that the increase in curing temperature has a positive effect as in the literature. Although the pressure values and sem images of the sewage sludge and oven slag samples may be suitable for use, this result could not be obtained in other experiments. In addition that, The sewage sludge has made a negative effect on the strength of the brick. However, it is suggested that using of the sewage sludges in the construction sector and researches should be continued.
