BS EN 1799 is a series on products and systems for the protection and repair of concrete structures. Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time.
BS EN 1799 specifies methods of testing to measure the suitability of structural bonding agents for application to vertical and horizontal surfaces.
BS EN 1799 on measure the suitability of structural bonding agents is useful for:
Concrete is the second-most-used substance in the world after water and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminium combined. BS EN 1799 describes a method for the determination of the suitability of structural bonding agents applied using a spreader to a vertical or horizontal surface, referred to as the “sag flow test”. BS EN 1799 also describes a method for the determination of the suitability of injectable structural bonding agents for application between two surfaces, referred to as the “squeezability test”.
Conditions required for the sag flow test states that Condition the resin and hardener components of the bonding agent and the sag flow board for at least 4 h at the test temperature of (21 – 2) 8C or an alternative test temperature as required. And the conditions for the squeezability test state that the condition of the resin and hardener components of the bonding agent as well as the plates for at least 4 h at the test temperature of (21 – 2) 8C or an alternative temperature as required. Using BS EN 1799 you can specify methods of testing to measure the suitability of structural bonding agents.
