Abstract: This study presents a review on use of industrial waste in concrete or mortar to understand their individual effect when used as filler and the filler effect when used either as replacement of fine aggregate or cement. Materials like limestone dust, ground quartz, carbon black and marble dust sewage sludge are reviewed. Filler plays a significant role in concrete not only contributing to strength improvement and other properties in concrete but also as a replacement of fine aggregate or cement, especially when waste materials are use. This process will help eliminate environmental hazards and minimize the excessive consumption of conventional materials like fine aggregate and cement where the sources are becoming scarce and expensive. However, it was observed from the reviewed literature that in replacement level of some of this materials as filler with respect to the percentage that will contribute towards improving the properties of the concrete, the replacement should be typically below 30% for a sustainable concrete. As the particle size of the filler has an effect on the performance of the concrete or mortar, it is also observed that the suitable particle size range of the filler was below 65 μm for optimum result whereby reducing the total porosity of the concrete and mortar.
