Effective Utilization of Industrial Wastes for Preparing Polymer Matrix Composites: Usage of Industrial Wastes

Background

The effective utilization of industrial wastes fly ash and rice husk as potential particle replacement for cement has been done by Satish et al. (2013) in which the compressive strength, flexural strength and tensile strength of the concretes made by mixing fly ash and rice husk in different weight proportions along with cement gives increase in strength. With fly ash as nano filler and micro filler, Al₂O₃, TiO₂ used as reinforcement along with epoxy matrix. Further the mechanical properties studies has been analyzed and noted that the strength decreases with the increasing content of the micro fillers and nano fillers (Ozsoy et al., 2015). In addition to the fly ash filler Nithin Kumar et al. (2015) carried out studies on wood powder as filler on the polymer composites produces promising increase in the mechanical strength. The effect of rice husk silica filler reinforced with high density polyethylene has been studied by Midhun Dominic et al. (2014) in which the surface modification done by using hydrochloric acid and inferred that the mechanical properties of the same higher than that of the pure polymer. The problems related to the disposal of wastes such as fly ash, slags from energy mining and metallurgical industries can be solved by potentially utilizing the waste with geopolymers for producing new composites replacing the existing cementitious materials (Korniejenko et al., 2015).
