Possibilities of increasing the durability of concrete products based technologies hardening their surface
Minaříková, Kateřina ; Eger, Lukáš (referee) ; Hubáček, Adam (advisor)
In the last years, we focus on higher quality of surfaces in the field of vibro-pressed concrete products. Therefore, there are products with specially modified backing layer in the market where there is implemented impregnation coating on the surface that is cured by ultraviolet and infrared radiation. The primary objective of my thesis is summary of the existing knowledge about vibro-pressed concrete products that are modified by these technologies. I will especially focus on description and efficiency of using particular methods, principals of curing surfaces and other modification of concrete product’s surfaces with emphasis on its durability. There will be examined in the laboratory conditions some of the characteristics of these vibro-pressed concrete products as resistance of surfaces against water effects and chemical defrosting substances, water absorption of surfaces, abrasion resistance, slip resistance, as well as risk reduction of creating lime efflorescence on the concrete surfaces.
