Descrição: dc.descriptionThis study describes the production of nanocement (NC) using an efficient catalyst for the in-situ synthesis of Carbon Nanotubes (CNT) directly on Portland cement grains. The application of NC in mortar is straightforward and does not require the use of additives, surfactants, or any other agent to achieve homogeneous dispersion. The results show that incorporating 0.2 % NC (1 g) to replace 10 % of the Portland cement (39.5 g) in mortar not only reduces traditional cement usage and, consequently, the environmental impact by lowering CO2 emissions by approximately 20 %, but also enhances mechanical properties, resulting in an increase of up to 33 % in compressive strength. The research includes an in vitro biocompatibility assessment using MRC-5 cells, a normal human lung fibroblast cell line. The tests demonstrate that both CNT and mortar containing NC are highly biocompatible (over 90 %). This makes NC a promising candidate for the safe application of CNT in cementitious matrices, while addressing environmental concerns. From both technological and innovative perspectives, NC represents a carbon-based alternative material with lower CO2 production and transportation costs compared to Portland cement, supporting its potential future classification as a green material.-
