Coal Tar Epoxies. Coal tar epoxies are economical and are commonly used on concrete and steel to protect against mild chemical attack and abrasion. Coal tar adheres well to bare concrete and is relatively easy to apply with spray, brush, or roller.
Coating types typically used during the curing of concrete include water-based styrene acrylic or acrylic emulsions. Additionally, surface applied coatings are beneficial for cured concrete. Although concrete is very durable under UV light and potable water, cured concrete is subject to several types of chemical attack that can degrade the ...
Surface treatment of a concrete loor is a process of successive stages (preparation, absorption, painting, application of mass and coating). Such treatment has a positive effect on the floor’s functionality and other similarly important issues.
Epoxy coatings protect concrete and steel which are exposed to mild chemical attack from sources such as acid mist, organic acids and water containing corrosive chemicals. Concrete surfaces are often porous, subject to bacterial growth and difficult to clean.
wet sprayed concrete. In both spraying processes, the base mix passes through the nozzle at very high speed (ca. 30 – 40 m/s). The jet is formed and the other relevant constituents of the mix are added, such as water for the dry sprayed concrete, compressed air for the dense flow pro-cess and shotcrete accelerators if required.
The sprayed concrete possesses a water cement ratio that is lesser than a conventional poured concrete. This condition is seen more in the dry process, where sagging is avoided by a lower water-cement ratio.
