Abstract: Quantities of sludge from septic tank and quarry rock dust from industries have been on the rise in recent years due to the rapid improvement in the standard of living and the increase in industrialization. Unfortunately, the majority of sludge from septic tank is not being recycled and hence it causes serious problems on natural resources and environment. For these reasons, this study has been conducted through basic experimental research in order to analyze the possibilities of recycling the sludge from septic tank as a supplementary material in cement concrete. In this research various proportions of septic tank sludge and quarry rock dust are used as supplement to sand in cement concrete and also various proportions of bacterial solutions are used as a supplement to water. The works under taken here dealt with the use of quarry rock dust, septic tank sludge and bacterial water as a supplementary material in cement concrete. In this investigation ,% of water absorption and compressive strength criteria were analyzed by introducing septic tank sludge, quarry rock dust and bacterial solution into the cement concrete

Keywords: recycling, septic tank sludge, quarry rock dust
