“…On the other hand, epoxy resins coating depends on the curing agents such as acids and amines. Acrylic coating applied on concrete showed the presence of small amount of VOCs [102]. The analysis indicates that weathering had no effect on the permeability of carbon dioxide, and the material's effect on its vapor permeability was insignificant.…”

Today, the building and construction sector demands environmentally friendly and sustainable protective coatings using inorganic coating materials for safe, non-hazardous, and great performance. Many researchers have been working on sustainable solutions to protect concrete and metal infrastructures against corrosion and surface deterioration with the intention of introducing green alternatives to conventional coatings. This article presents a review of developments of geopolymer pastes doped with different types of photocatalyst precursors including factors affecting geopolymer properties for enhancing coating with photocatalytic performance. Photodegradation using geopolymer photocatalyst has great potential for resolving harmless substances and removing pollutants when energized with ultraviolet (UV) light. Although geopolymer is a potentially new material with great properties, there has been less research focusing on the development of this coating. This study demonstrated that geopolymer binders are ideal precursor support materials for the synthesis of photocatalytic materials, with a significant potential for optimizing their distinctive properties.

“…The acrylic resin is of high quality, low viscosity, high elongation percentage, and so on [11]. Acrylic covers demonstrate good adherence to the concrete substrate and, also, show good alkali resistance [12]. One more useful feature of acrylic coatings is their significant stability to atmosphere action.…”

This paper aims to reveal the change of diffusion coefficient and permeability of the acrylic composition with different types of fillers (such as cement, sand, mica, and talc) in the various aggressive mediums. Also, the adhesive strength was determined as the maximal stress caused by detaching metal plate from the surface of the concrete. To evaluate the stability of the compositions, the samples of the acrylic compositions were saturated with acid and alkali solutions during a certain time. Basing on the mass change, the coefficients of diffusion, sorption, and permeability were calculated. The sand filled acrylic composition showed the least sorption (0.2%) and water permeability (0.008 gÃ—cmâ€“1Ã—sâ€“1), as well as the highest adhesion strength (53.2 MPa). However, all studied compositions satisfy the requirements of the current permeability standards, and they can be used for construction protection from the aggressive environment action. It is important for the durability of the structures as it will prolongate their operative time, as well as reduce the operating and repair costs.

Ziel dieser Arbeit ist die Untersuchung der Veränderung des Diffusionskoeffizienten und der Durchlassfähigkeit einer Acrylzusammensetzung mit verschiedenen Arten von Füllstoffen (Zement, Sand, Glimmer, Talk) in verschiedenen aggressiven Umgebungen. Für die Bewertung der Stabilität von Zusammensetzungen in aggressiven Umgebungen wurden die Proben von Acrylzusammensetzungen im Laufe einer bestimmten Zeit mit Lösungen von Säuren und Laugen gesättigt. Nach der Massenänderung wurden Diffusions‐ und Permeabilitätskoeffizienten berechnet. Außerdem wurde die Haftfestigkeit als maximale Spannung bestimmt, die bei dem Abreißen einer Metallplatte von der Betonoberfläche auftritt. Die mit Glimmer oder Talkum gefüllten Acrylzusammensetzungen zeigten die niedrigste Sorptionskapazität und Wasserdurchlässigkeit. Die mit Glimmer gefüllten Beschichtungen hatten die höchste Haftfestigkeit. Alle untersuchten Zusammensetzungen erfüllen jedoch die Anforderungen von geltenden Normen für die Wasserdurchlässigkeit und können zum Schutz von Bauwerken vor aggressiven Auswirkungen verwendet werden. Dies ist wichtig für die Dauerhaftigkeit von Bauwerken und senkt die Betriebs‐ und Reparaturkosten.
