What is BS EN 1771 - Injectability and splitting test of concrete structures about?
BS EN 1771 specifies a method for determining the injectability of a product in a capillary network and its adhesion to concrete by measurement of the splitting strength of cylindrical mortar samples resulting from a sand column injection.
Who is BS EN 1771 - Injectability and splitting test of concrete structures for?
BS EN 1771 on injectability and splitting test of concrete structures is useful for:
- Construction industries
- Civil engineers
- Testing laboratories of concrete structures
- Manufacturers of concrete
- Designers
- Builders
- Contractors
Why should you use BS EN 1771 - Injectability and splitting test of concrete structures?
Sand is used for cement tests; instead of siliceous sand, for special purposes, crushed cement mortar of the same grading is used (for instance if the simulation of the concrete capillary is intended).
BS EN 1771 specifies the test for measuring the rate of flow of the injection agent through a column of graded sand. BS EN 1771 specifies the method of injection uses a fixed quantity of mixed reactive injection agent in a vessel maintained at a closely controlled pressure, to provide the injection force.
BS EN 1771 provides a test on injecting, under constant pressure, the product is a transparent plastic (polymethylmethacrylate) tube filled with graded sand and kept in a vertical position.
Overall, BS EN 1771 provides a useful comparison between materials, giving some indication of the strength of the bond achievable.
