A Compressive Strength Model for Silica Fume Pervious Concrete: A Sustainable Material
Pervious concrete, known for its high void ratio, facilitates direct water permeation, effectively replenishing the groundwater table. Nonetheless, its widespread application has been limited to low-traffic roads, sidewalks, and parking lots due to its relatively lower strength. To surmount this challenge, the use of admixtures, i.e., Silica fume, stands out as a promising partial cement replacement in this study, aimed at bolstering the concrete's strength. This research delved into enhancing various critical attributes of pervious concrete, including workability, void content, compressive strength, and flexural strength. The study employed varying proportions of Silica Fume, ranging from 7 to 11%. Among the investigated compositions, the most promising results emerged when 9% Silica Fume in combination with a cement content of 440 kg/m3 was utilised. This formulation demonstrated remarkable improvements in both compressive strengths, reaching an impressive 28.018 N/mm2, and flexural strengths, achieving 2.78 N/mm2, and when compared to traditional pervious concrete, these figures represented significant enhancements of 18.86% and 60.6%, respectively, highlighting the effectiveness of the innovation. In order to establish a predictive model for the compressive strength of pervious concrete, the researchers factored in the percentages of Silica Fume, cement content, voids, and slump value (mm). This approach enabled the development of a robust model that can assist in optimising the concrete's strength while retaining its permeable characteristics. Overall, this study opens up new avenues for the application of pervious concrete in a broader range of construction projects.
