Exploring Limestone Alternatives for Sustainable Concrete Solutions

Created using ChatSlide

In this presentation, we delve into an advanced study conducted by a team of experts at CTB-IBC Laboratory in Rzeszów, investigating the effectiveness of replacing fly ash and fine aggregates with limestone powders and sands in concrete mixtures. Following precise methodologies aligned with industry standards, such as PN-EN 480-1:2014-12 for batch preparation, the findings reveal a neutral impact on rheology but highlight challenges like air content and strength variability.
