Linz-Donawintz (LD) slag is a solid waste produced during the basic oxygen furnace process of steel making and is more often disposed of on nearby land causing a disturbance in vegetation and human health. Hence, judicial management of LD slag is a need for an hour. For this purpose, the usability of LD slags as a reinforcement material in epoxy composites was investigated in the present work. In this investigation, the physical properties (density, void content, water absorption rate), mechanical properties (tensile properties, flexural properties, compressive strength, hardness), and tribological properties (sliding wear behavior) are reported. From the experimental investigation, it is found that the density, void content, and water intake capacity increase with LD slag loading. The maximum voids present in the composite is 1.92% for epoxy/40 wt. % LD slag composite. Similarly, maximum water uptake of only 0.6% is observed for composite with maximum filler content and for maximum immersion time. Further, it is observed that the strength of composite under tensile and flexural loading was compromised slightly. At 40 wt. % of LD slag, the measured tensile and flexural strength are 20.8 MPa and 28.78 MPa respectively. The strength of composites under compressive loading increases with filler content and reaches a maximum of 108 MPa for epoxy/40 wt. % LD slag composite. The high hardness of filler assists in increasing the hardness of the composites. The hardness of neat epoxy is Shore-D number 75 which increases to Shore-D number 84. With increased hardness, ultimately the specific wear rate under dry sliding conditions reduces. Taguchi's L 25 orthogonal array having four factors, each at five different levels is implemented to conduct the sliding wear tests. A forecast model is built on an artificial neural network (ANN) which successfully envisages the sliding wear performance of the composite under investigation inside and outside the experimental domain.

Ground granulated blast furnace slag (BFS) and fly ash (FA) are iron-making industry and power plant byproducts, respectively. Although their use in concrete is quite common, investigation of the effects of these inorganic compounds on polymer properties is quite new, and their use as fillers in polymer foam composites has not yet been really explored. Their properties, such as high electrical resistivity, make them a good asset for use in rigid polyurethane foams that are widely used for insulation. In this study, a comprehensive investigation of the effect of BFS and FA on morphology, electrical and thermal conductivity, and rheological and mechanical properties of water-blown rigid polyurethane foams was performed. The relationship between these properties was examined. A relative enhancement of the properties is observed for filled foams, especially up to the percolation threshold. The results highlight a noticeable effect of the electrical percolation threshold on the different properties of foams.

“…Based on the fact that naturally occurring minerals, such as kaolin, clay, and feldspar, are widely used in the polymer‐based composites , it could be concluded that slag which is a mixture of oxides could also used as a reinforcement for polymer composites. In this regard, only few studies on the use of slag as filler in polymer composites are available in the literature . For example, it has found that slag was able to improve the tribological properties of an epoxy composite .…”

Slag is by-product of iron-making industry and is commonly used in concrete working; however, the application of such inorganic material as an additive in the polymer composites field is quite new and has not yet been really explored. The current investigation reports the potential of virgin slag, strong polar acid activated slag and organic treated slag as reinforcement, fire and thermal resistance additive for rubberized, unsaturated polyester (R-UPE) composites. The slag was subjected to three pretreatments, the first was mechanical (comminution) to reduce the particle size, the second was chemical activation by strong polar acid namely H 2 SO 4 , and the third was coating by organic stearic acid. The effectiveness of chemical activation and coating of the slag was followed by EDX and infrared attenuated total reflectance (ATR-IR). The potential of activated and coated slag as reinforcement for rubberized, unsaturated polyester resin was evaluated and compared to the sample with pristine slag. The fabricated composites were evaluated with respect to their mechanical mechanical behavior. Thermal behavior was inspected using behavior using differential scanning calorimeter (DSC), dynamic mechanical analysis (DMA) was investigated. Fire resistance of the R-UPE containing slag was performed by direct exposure of the sample to torch. It has been found that the activated slag has improved the concerned properties. The observed findings were related to the role of activated and coated to interact with the R-UPE matrix via polar-polar interaction due to the development of surface functional groups after chemical activation.
