What is BS EN 480-13 - Masonry mortar for testing mortar admixtures about?
BS EN 480 is a European standard that discusses test methods for admixtures for concrete, mortar and grout. The main aim of the BS EN 480 series is to provide best industry guidance to ensure construction materials contribute to the structural integrity of your civil engineering works.
BS EN 480-13 is the 13th part of the BS EN 480 series that specifies the constituent materials, the composition and the mixing procedure to produce a reference masonry mortar with a prescribed consistence for testing mortar admixtures as defined in EN 934-3.
BS EN 480-13 also describes the determination of the water reduction of the test mix compared to the control mix.
Who is BS EN 480-13 - Masonry mortar for testing mortar admixtures for?
BS EN 480-13 on admixtures for concrete, mortar and grout is useful for:
- Manufacturers of admixtures for concrete, mortar and grout
- Quality control and testing personnel
- Civil engineers
- Contractors
- Concrete specialists
Why should you use BS EN 480-13 - Masonry mortar for testing mortar admixtures?
Mortar admixtures are used to bond masonry or other structural units forming an even and soft bedding layer for building units and to improve the general appearance of a structure. To ensure the durability and quality in the construction of modern infrastructure, various types of admixtures are used as additives in concrete, grout and mortar.
BS EN 480-13 provides the measure of constituent materials used for making concrete, mortar and grout.
BS EN 480-13 outlines the production of reference mortar with standard consistence for test after standing and after extended mixing.
Calculation method for water reduction (air entraining/plasticizing admixtures) and test mixes of cement, sand and consistence for testing mortar admixtures are set out in BS EN 480-13.
As a result, manufacturers can ensure the quality of concrete throughout mixing, transportation, placement, and curing, as well as overcome specific emergencies during concrete operations.
