Mechanical reinforcement of cement pastes with Cellulose Acetate microfibers produced by electrospinning.
Electrospun fibers have attracted much attention in various industries due to their distinctive qualities and possible uses, including construction. Electrospinning produces ultrafine fibers by exposing a polymer solution or melting to a high-voltage electric field. These fibers' nanoscale to micrometer sizes provides remarkable mechanical qualities and a high surface area-to-volume ratio. Electrospun fibers offer several benefits and modern advancements in the building construction industry, including increased strength and durability, improved energy efficiency, and environmental sustainability. The usage of electrospun fibers in the construction sector is still constrained, and areas still require improvement. Examples include pertinent parameters, scaling-up challenges, standardization, and regulations. As a result, the master has directed their efforts toward assessing a friendly method for the electrospinning process and innovative cement composites by reinforcing them with microfibers produced by their hand in the OsloMet Chemistry Lab to enhance flexural and compressive strength. Initially, two different fibers, mainly cellulose acetate (CA) and polyvinylpyrrolidone/tetraethyl orthosilicate (PVP/TEOS), were considered for this study. These fibers were produced through a process called electrospinning, which involves the use of electrical forces to create delicate and continuous fibers. The objective was to assess how different types of fibers could affect the mechanical properties of composites made of cement. However, the PVP/TEOS fibers disintegrated in water during the experimental phase, making them unsuitable for further investigation. Therefore, only cellulose acetate (CA) fibers were considered for this project. Three different mixes were prepared to examine the effect of CA on the final composite’s properties, each containing varying amounts of CA fibers: 0.1%, 0.5%, and 1%. Experimental results showed that CA significantly improved compressive strength at an early age. For instance, adding 1% CA ...
