What is BS EN 1742 - Shear strength of multilayer components made of ACC and LAC about?
BS EN 1742 is a European Standard on the performance test for prefabricated multilayer components of concrete. The main aim of BS EN 1742 is to provide the best industry guidance to ensure construction materials contribute to the structural integrity of your civil engineering works.
BS EN 1742 specifies a method of determining the shear strength under short-term loading between the different layers of prefabricated multilayer components made of autoclaved aerated concrete (AAC) according to prEN 12602 or lightweight aggregate concrete with open structure (LAC) according to prEN 1520.
This test method is suitable only for the evaluation of conformity purposes during the production of multilayer components.
Who is BS EN 1742 - Shear strength of multilayer components made of ACC and LAC for?
BS EN 1742 on shear strength of multilayer components made of ACC and LAC is useful for:
- Manufacturers of concrete and concrete products
- Construction materials manufacturers and suppliers
- LAC and ACC products manufacturers
- Civil engineers
- Contractors
- Quality control and testing units
Why should you use BS EN 1742 - Shear strength of multilayer components made of ACC and LAC?
A material's shear strength is defined as its capacity to withstand forces that cause the material's internal structure to move against itself.
The shear strength between different layers of a multilayer component is determined by applying a horizontal compression force acting in the longitudinal direction of the component at one end face on the bottom layer, while the component is laid in a horizontal position on two rollers supports near its ends.
In this regard, BS EN 1742 specifies the apparatus required and the shape, size, number, preparation, measurement, and conditioning of test specimens as well as the test procedure to evaluate the shear strength of multilayer components made of ACC and LAC.
As a result, if you are a manufacturer of aggregate components, complying with BS EN 1742 can demonstrate the performance and reliability of your products.
Overall, in structural and mechanical engineering, the shear strength of materials plays an essential role in the safe design of components.
