Resumo

This study explores the utilization of Al-anodizing waste (AAW), a byproduct from the anodizing process of aluminum and aluminum alloys, to modify the rheological properties of cement composites designed for 3D printing applications. Cementitious materials intended for 3D printing must maintain stability and support the weight of printed layers while also exhibiting sufficient flowability and workability (open time) for pumping. Incorporating AAW aims to enhance the rheology of these mixtures, thereby improving both their workability and buildability. A comprehensive approach was employed to assess the potential of Al-anodizing waste (AAW) as a viscosity modifying agent (VMA) for 3D printing cement. This approach involved a number of analyses, including rheological analysis, flow table testing, and 3D printing of cement pastes. Additionally, complementary techniques such as isothermal induction calorimetry and in-situ X-ray diffraction were utilized to investigate how AAW influences hydration kinetics and variations in the composition of cement pastes. The findings revealed numerous advantages of incorporating AAW into cement-based formulations as a VMA. These benefits include enhanced buildability, rapid rheological adjustments, extended open times, reduced costs, and the promotion of sustainability by repurposing a commonly discarded material as a valuable resource.
