In this study fly ash and red mud solid waste are used in the preparation of polymer concrete. Utilization of waste such as fly ash and red mud in polymer concrete is promising; it may enhance the physical properties and mechanical strength of the polymer concrete.The mechanical properties of PCs with variation of different compositions of fly ash (8, 12%), red mud (12, 25%) and resin (30, 35%) has been investigated. The silica powder in different percentage (10, 15%) used as filler in polymer concrete has enhanced the mechanical properties of polymer concrete. The casted PCs were also investigated for their flexural strength.(For the preparation of samples Orthogonal array of Technique of Design of Experiments) is used). The PCs specimen with 35% resin, 25% fly ash and 15% silica fume resulted in maximum flexural strength. Generally, PC’s containg fine fillers may result in high mechanical strength due to high molecular compaction. The values of flexural strengths were 21.53 MPa.

Keywords: polymer concrete, red mud, fly ash, silica powder, flexural strength.
