REVIEW ON FILLER EFFECT OF VARIOUS NONREACTIVE MATERIALS IN CONCRETE

Fillers are particles added to the material or mixed in order to reduce the excessive utilisation of binderand at the same time improve some properties of the mixture, from past study several materials have been usedas fillers in the replacement of either cement or fine. This paper presents a review of past studies on the filler effectof various nonreactive materials as fillers. Materials like ground river sand, limestone dust, ground quartz, carbonblack, quarry dust and marble dust are reviewed. Based on analysis, it has been proven that filler plays a significantrole in concrete, not only contributing to strength improvement and other properties in concrete, but also whenused as a replacement for cement or fine aggregate, whereby minimizing the excessive consumption ofconventional materials. However, it can be concluded from past studies that in replacement level of the variousmaterials as filler in concrete, the replacement should be in the range of 2 to 15% for a sustainable concretestructure. Furthermore, as the particle size of the filler affects the performance of the concrete, it is thus concludedthat a finer particle size range of the filler should be in the range of 0.025 to 6μm for better results and filling abilityor particle packing.
