THE INFLUENCE OF SILICA-COATED NANOSCALE TITANIUM DIOXIDE ON THE MICROSTRUCTURE, MECHANICAL PROPERTIES, AND CARBONATION RESISTANCE OF CEMENTITIOUS MATERIALS

The influence of silica-coated nanoscale titanium dioxide on the microstructure, mechanical properties, and carbonation resistance of cementitious materials

Nanomaterials possess great application prospects in improving the performance of cementitious materials.However, their high agglomeration hinders their efficient utilization in cementitious matrices.Consequently, surface modification has recently attracted attention as a method to enhance dispersibility.In this study, silica was employed to modify
