Znaczenie inżynierii powierzchni w naprawach betonu

Recently, an efficiency of concrete repair is treated as the civilizing challenge. This was also the genesis to elaborate family of European standards EN 1504. The part 10 of this standard gives requirements for substrate condition before and during application including structural stability, storage, the preparation and application of products and systems for the protection and repair of concrete structures including quality control, maintenance, health and safety, and the environment. According to this standard a suitable preparation of concrete substrate prior a repair is considered as the one of the important factors affecting durability of concrete repair. Recently, experiences in this filed is ordered in the framework of scientific approach called concrete surface engineering. The main goal of this approach is analysis of qualitative and quantitative relationships between surface quality and repair durability. The aim of this paper is to analyze an effect of surface treatment on surface quality and adhesion in repair system using concrete surface engineering approach.
