Special Issue Information

Dear Colleagues,

The surfaces of building materials are subject to weathering, dirt, and abrasion by common use. To amplify the service life of exposed building materials, coatings and surface treatments compatible to the substrate can be applied. Surface coatings and treatments with bio-based products have long been a possibility but have recaptured the attention of researchers and industry in recent years, mainly due to environmental and health-related concerns. Bio-based materials that can be applied directly or used to formulate bioproducts can be remarkably diverse. Natural oils, such as linseed oil, waxes, and other bio-based materials, can be applied directly to treat building material surfaces. Animal fats, plant mucilage, and others can be incorporated in lime putties to improve multifunctionality when used for limewash or to formulate rendering mortars. Recent theoretical and experimental developments have benefited from vernacular practices and resulted in innovative products with multifunctional performance. Such is the case of bioproducts developed from bacteria, enzymes, or biopolymers. Production, availability in terms of packaging and transport to the working site, application technologies, health application concerns for workers and society, testing, compatibility with the substrates, durability under on-site conditions, economical and environmental assessment, and numerical simulations validated by data are all aspects that need further research and dissemination.

Although not closed to other related concepts, this Special Issue will serve as a forum for articles on the following concepts:

  • State-of-the-art vernacular and innovative bioproducts and biotreatments applied on building material surfaces;
  • Bioproduct production and biotreatment application techniques, considering societal, economic and environmental concerns;
  • Specific test methods to assess bioproduct and biotreatment efficiency, surface compatibility, and durability in laboratory and on-site conditions;
  • Experimental results of simple to multifunctional biotreatments, exposed to conditions ranging from common to extreme;
  • Numerical simulations to predict bio-based coating product properties, performance, durability, and reliability in service environments;
  • Environmental assessment of innovative bioproducts for building surfaces, namely in comparison to inorganic ones.

Improving the protection of concrete by applying graphene oxide (GO) as a surface treatment has become the objective of the present study. This study focuses on performing a statistical analysis to study different levels of GO application as an exterior coating, thus observing the effectiveness of the coating and the optimization of the treatment material for concrete protection. Four tests were performed to define concrete durability, such as pressurized water penetration, capillary absorption, freeze-thaw resistance and carbonation resistance. The results showed an increase in concrete durability with any level of GO application on the surface, considering that the optimum amount of application for water impermeability and freeze-thaw resistance is 26.2 µg/cm2, since it was possible to reduce pressurized water penetration by 45%, capillary water absorption by 57% and freeze-thaw detachment by 25%. However, the optimum application rate for carbonation resistance is 52.4 µg/cm2, reducing carbonation by almost 60%. In conclusion, if the concrete is going to be exposed to less aggressive environments, the application of a mild surface coating of GO is sufficient for its protection, and if the concrete is going to be exposed to more aggressive environments, it is necessary to increase the amount of GO. The performance of GO as a coating significantly increased the degree of protection of the concrete, increasing its service life and proving to be a promising treatment for concrete surface protection.
