This research paper examines the effect of titanium dioxide (TiO2) on the compressive strength of concrete with an emphasis on the properties and functionality of photocatalytic concrete in comparison to conventional concrete. The basic ideas of photocatalytic concrete, with its advantages for the environment and aesthetics, will be briefly discussed. The study will compare photocatalytic concrete’s compressive strength to that of regular concrete to evaluate its mechanical properties. The main focus of this research paper is compressive strength because it is a crucial factor in determining a concrete’s capacity to support loads. The study will analyze and evaluate four distinct testing methods for determining the compressive strength of samples with varying titanium dioxide addition percentages. Through the methodological measurement and analysis of these findings, this study seeks to clarify how titanium dioxide affects concrete’s mechanical qualities. The final goal of the study is to determine whether photocatalytic concrete has a higher compressive strength than conventional concrete.
