INFLUENCE OF ACCELERATED CARBONATION CURING ON THE MECHANICAL AND DURABILITY PROPERTIES OF LIMESTONE CALCINED CLAY CEMENT MORTAR

Abstract

The construction industry is increasingly focus on sustainable building materials to reduce its environmental impact. Limestone Calcined Clay Cement (LC3) has emerged as a promising eco-friendly alternative to traditional Portland cement, this research investigates the effects of Accelerated Carbonation Curing (ACC) on the mechanical and durability properties of LC3 mortar, with a specific emphasis on the incorporation of cement substitution materials. LC3, known for its reduced carbon footprint, combines limestone and calcined clay as primary constituents, offering an opportunity for sustainable cement production. To enhance its properties, various cement substitution materials such as fly ash, slag, and silica fume are introduced. ACC, a novel curing technique, is employed to expedite the carbonation process, which can enhance the material’s strength and durability. This study assesses the influence of ACC on LC3 mortar, considering parameters like compressive strength and water absorption. The incorporation of cement substitution materials further enriches the investigation, evaluating their synergistic effects with ACC on the performance of LC3 mortar. The results reveal significant improvements in mechanical strength and durability properties of LC3 mortar when subject to ACC, highlighting its potential as an effective curing method. Additionally, the study elucidates the role of cement substitution materials in enhancing the overall sustainability and performance of LC3-based construction materials. This research contributes valuable insights into the influence of ACC on LC3 mortar, with a particular focus on the role of cement substitution materials. These findings have the potential to shape the future of sustainable construction practices, offering a pathway to reduced carbon emission, improved material performance, and enhanced environmental sustainability in the construction industry.
