What is BS EN 445 - Testing grout for prestressing tendons about?

BS EN 445 is a European Standard for testing grout for prestressing tendons. The main aim of BS EN 445 is to provide the best industry practices that ensure the grout is fit for purpose and plays a positive role in the durability of your structures.

BS EN 445 describes the test methods for grout specified in EN 447. Testing shall be performed

in accordance with the test methods given in BS EN 445 (reference test methods).

The test methods are applicable to grout for all types of structures including bridges and buildings.

Who is BS EN 445 - Testing grout for prestressing tendons for?

BS EN 445 on testing grout for prestressing tendons is useful for:

Manufacturers of concrete and concrete products
Construction material industry
Grout manufacturers
Cement industry
Builders and contractors
Civil engineers
Architects

Why should you use BS EN 445 - Testing grout for prestressing tendons?

In post-tensioned prestressed concrete construction, the grouting of tendons is an important operation. The main objective of grouting is to protect the steel from deterioration due to corrosion and to provide a bond between the tendons and the concrete member after tensioning.

In this regard, BS EN 445 specifies the apparatus, test techniques, and test procedures required for testing grouts, which include the sieve test, fluidity test, inclined tube test, wick-induced test, and compressive strength test, and density test.

Overall, grouting protects the tendon from possible corrosion that helps in maintaining pre-stress force reduces losses and protects the structure from sudden failure if local damage takes place to the tendon.

As a result, if you are a manufacturer of grout, testing in compliance with BS EN 445 can demonstrate the performance and quality of your products.
