One way of strengthening prefabricated cement is to use metal mats or cages for reinforcement.
BS EN 1737 is a European Standard that specifies a method of determining the shear strength of welded joints in reinforcements intended for use in prefabricated components made of autoclaved aerated concrete (AAC) according to BS EN 12602 or lightweight aggregate concrete with open structure (LAC) according to BS EN 1520.
BS EN 1737 on welded joint shear strength for prefabricated concrete is useful for:
To reinforce the prefabricated concrete product, the quality of the weld is as important as the quality of the metal.
As per BS EN 1737 guidelines, the shear strength of welded joints is determined on test specimens consisting of a longitudinal bar and a welded transverse bar or diagonal bar. BS EN 1737 walks you through the tests by guiding you with test specimens; in terms of their shape and size, their quantity, as well as the preparation, measurement, and conditioning of these test specimens. Diagrams have been used to illustrate the testing device, the auxiliary device, as well as the specimens.
BS EN 1737 guides you through tests to assess the strength of welds so that the prefabricated product is up to code and performs as intended. This enables the finished product to be long-lasting.
