The application of surface treatment on all types of concrete has been widely introduced over the past years. The surface treatment technology is becoming more and more significant in any concrete structure, especially in preventing deterioration and damage when the concrete is exposed to aggressive environments.
What is Surface Treatment?
Surface treatments are used to improve the surface of a structure. Reasons could be to enhance corrosion protection, wear friction and resistance control. Surface treatments are broadly used in most industries for improving surface properties.
Types and Mechanisms of Surface Treatments
Based on the chemical composition of surface treatment agents, they can be divided into 2 categories: organic and inorganic treatments. The following sections are the major types of surface treatments discussed in detail.
- Polymer Coatings – Acrylic, polyurethane and epoxy resins are polymer protective coatings which have been used in the construction industry for many years. Most chemical manufacturers in UAE recommend this coating due to the benefits that comes with it, including low shrinkage, easy to cure, chemical resistant, good adhesive strength, high resistance to ultraviolet radiation, and excellent resistance to weathering.
- Polymer Nano-composite Coatings – recently, nano-composite polymer coatings have gained interest in both engineering and research because of their remarkable properties over the traditional polymers. Nano-composite polymer coatings normally have higher durability, improve abrasion resistance, heat resistance, and thermal solidity. The presence of nanoparticles could lessen gas permeability and flammability. While the addition of inorganic composite can enhance the barrier properties and slow down the deprivation of polymers by increasing the diffusion path.
- Cementitious Coatings – Polymer modified cementitious coatings are the usual cementitious coatings used for concrete protection. These coatings are made with polymer such as acrylate, epoxy or polyurethane that are also combined with cement and aggregates. The addition of polymer significantly enhances the properties of durability, resilience, chemical resistance, adhesion and impermeability of the cement paste.
Corrotech Construction Chemicals
Corrotech construction chemicals is one of the leading UAE construction chemical companies. They have a wide array of construction chemicals, including surface treatments that compromises water, wax and acrylic based curing compounds. All the surface treatments they offer have been designed to treat fresh concrete surface, block, and pavements.
