“…It is a well-established fact that there exists an inverse relationship between porosity and the strength of cement stone. In theory, the maximum strength of cement stone can be achieved when capillary porosity approaches zero [51][52][53][54][55][56][57][58][59][60][61][62][63][64][65][66][67][68].…”

“…In some instances, precipitated SiO 2 is integrated into the composition of RPC concretes alongside microsilica. This inclusion contributes to achieving compressive strength ranging from 200 to 800 MPa and flexural strength of up to 100 MPa [55][56][57][58][59][60][61][62][63][64][65][66][67][68][69].

The integration of nanotechnology across various industries has significantly enhanced product quality and manufacturing technologies for diverse materials. Within the construction sector, the adoption of nanomaterials has sparked the advent of innovative construction methods. Extensive studies have been conducted on various nanomaterials, particularly micro- and nanosilica, exploring their use as partial substitutes for cement in concrete formulations. This study aimed to furnish a comprehensive overview of silica’s impact on concrete properties in civil engineering and road construction. Environmental concerns and potential hazards necessitate the development of strategies for managing industrial by-products. Metallurgical processes generate several such by-products, among which is silica fume—a residue from smelting in the silicon and ferrosilicon industries. Waste silica dust and slurries have proven highly effective in creating high-strength, high-performance concrete. The study presents a literature review focusing on micro- and nanosilica derived from production waste at ferroalloy and silicon plants. It includes a comparative analysis of the primary characteristics of microsilica from various sources and examines the extensive use of microsilica as a modifying additive in building materials. Analyzing different concrete compositions with and without fumed silica determined the ranges of results for each indicator. The incorporation of micro- and nanosilica into the concrete mix demonstrated its efficacy. The morphology of waste silica particles, characterized by the smooth and spherical surfaces of micro- and nanosilica particles, significantly influences the workability properties of the concrete.

“…However, more amount of material in the form of debris usually occurs at higher load which produces more mechanical rubbing action between the counter disk and the tested sample. This result produces severe wear due to adhesion followed by abrasion as the load increases from low to high [19]. Further, linear wear behavior was observed for all cast samples [20] and the composite samples produced less wear rate due to heat treatment and the presence of high hardened more weight percentage SiC particles [21].…”

“…The results demonstrated that the wear rate was highly influenced by applied load, then sliding distance and sliding speed. Manu et al [19] studied the microstructure and mechanical properties of A356 alloy reinforced with 7 wt% of microsilica composite which was manufactured by modified compo-casting. The A356 alloy reinforced with microsilica composite produced higher hardness compared to other processing methods (gravity die casting and squeeze casting).…”

The goal of this research work is to assess the tribological properties of A356 alloy reinforced with 20 wt% SiC composite prepared by liquid metallurgy route. A356 alloy and A356 with 20 wt% SiC composites were manufactured through three different casting techniques such as gravity die casting, stir casting and stir cum squeeze casting. The fabricated castings exhibit improved hardness value of around 680 MPa, 840 MPa and 950 MPa for A356 alloy, A356 with 20 wt% SiC stir cast composite and A356 with 20 wt% SiC stir with squeeze cast composite, respectively. Further, an ultimate tensile strength of 256 MPa, 298 MPa and 331 MPa was obtained for A356 alloy, A356 with 20 wt% SiC stir cast composite and A356 with 20 wt% SiC stir with squeeze cast composite, respectively. The tribological properties of prepared samples were tested using a pin-on-disk tribometer at room temperature under dry sliding condition. The wear results explained that the wear rate and coefficient of friction started to increase with the function of load (10-40 N) under both the sliding distance of 1000 m and 2000 m. The squeeze cast A356 with 20 wt% SiC composite produced less wear rate and a higher coefficient of friction when compared to other samples. This was attributed to effective embedding, bonding and load-carrying capacity of SiC particles over the A356 matrix. This result indicates improved adhesive properties and abrasion resistance in the squeeze cast A356 with 20 wt% SiC composite. Further, the worn surface morphology of squeeze cast samples was examined using a scanning electron microscope to observe mild adhesive wear and damages due to the delamination effect.

This work concentrates on the preparation of AA6061/(0, 2, 4, 6, 8 wt.%) rice husk ash (RHA) aluminum matrix composites (AMCs) using compocasting and investigation of the dry sliding wear behavior by means of pin-on-disc apparatus at room temperature. The microstructures of the composites were studied using scanning electron microscopy and electron back scattered diffraction. The micrographs confirmed successful incorporation of RHA particles into the aluminum matrix. A proper distribution of RHA particles without segregation was achieved. RHA particles refined the grains of the aluminum matrix and improved the wear resistance of the composite. The influence of RHA particulate content and applied load on the worn surface and wear debris was further reported. RHA particles improved the wear resistance of the composites and reduced the damage on the worn surface. The wear mode changed with increase in the content of RHA particles and the applied load.
