Abstract/Summary
Titanium has the potential to increase the compressive strength of concrete. This experiment investigates the impact of titanium admixture on concrete compressive strength, using three different forms of titanium: shavings, flakes, and powder. This experiment goes further, evaluating the effects of varying proportions of titanium admixture, ranging from 1% - 5% by the weight of cement, resulting in 15 different concrete test cylinders and one additional cylinder as the control variable with no titanium admixture. This experiment aims to identify the optimal recipe for concrete mix with titanium admixture which can provide valuable insight to the industry as to how titanium can be recycled and how concrete structures can be made stronger and more durable while potentially reducing materials use. The hypothesis suggests that titanium powder will yield the highest strength due to the maximized surface area coverage and its ability to bond with the cement. The results of this study align similarly with previous studies that use titanium dioxide as an admixture in concrete. While titanium nanoparticles (TiO2) have been shown to reduce porosity, promote hydration, and increase compressive strength in concrete, there is limited research on larger titanium particles and how they affect the properties of concrete.
