Impact of Petroleum Products on the Compressive Strength of Concrete

Abstract

Background: Concrete is pivotal in construction due to its strength, affordability, and versatility. However, concerns persist regarding the impact of petroleum products like benzene, kerosene, and diesel on concrete strength. This study evaluates their influence on concrete compressive strength and compares their effects with non-contaminated concrete.

Objectives: The study aims to investigate the effects of benzene, kerosene, and diesel on concrete strength. Additionally, it compares different curing methods, specifically immersion in contaminants versus traditional water curing, on concrete strength.

Methods: 327 standard concrete cubes (150mm x 150mm x 150mm) were cast and divided into four groups based on curing methods. Compressive strength tests were conducted on both control and contaminated samples. Statistical analysis using SPSS software was employed.

Results: All compressive strength values exceeded 100% of the designed concrete compressive strength of K-300. Curing in contaminants positively impacted concrete strength compared to water curing, with kerosene immersion showing the most significant increase. Statistical analysis confirmed the significant positive impact of pollutants on concrete strength.

Conclusion: This study underscores the importance of considering petroleum product contamination in concrete construction. Further research is warranted to elucidate the mechanisms underlying the increased compressive strength, potentially linked to the hydrophobic-plasticizing effect of petroleum products.
