Comparative evaluation of photocatalytic efficiency measurement techniques thro...
Lessa, Fabíula Pereira; Lima Jr., Orlando; Margalho, Élida Melo; Zahabizadeh, Behzad; Cunha, Vítor M. C. F.; Pereira, Eduardo; Camões, AiresSelf-cleaning cementitious materials, particularly with TiO2-based photocatalytic coatings, offer significant benefits by reducing surface deterioration and maintenance requirements, even in harsh urban environments. Despite the growing interest in self-cleaning cementitious materials, an international standard test method to calculate their efficiency has not yet been established for this specific type of subs...
Assessment of self-cleaning properties on concrete façade panels
Lessa, Fabíula Pereira; Júnior, Orlando Sousa Lima; Margalho, Élida Melo; Pinheiro, Claver Giovanni Silveira; Rocha Segundo, Iran Gomes daBuilding façades are affected by atmospheric pollution and other external agents that can impact aesthetic aspects and lead to the appearance of anomalies with impacts on the durability and performance of materials. The reduction in maintenance costs and the preservation of the original characteristics of coatings make the use of photocatalytic semiconductor materials highly attractive, particularly for the con...
