What is BS 4550-6- Standard sand for mortar cubes about?
Well-graded sand increases the density and performance of mortar.
BS 4550 is a British Standard that discusses methods of testing cement.
BS 4550-6 is the sixth part of the series that specifies the source, preparation and properties of a standard sand to be used for making mortar cubes.
Who is BS 4550-6- Standard sand for mortar cubes for?
BS 4550-6 on standard sand for mortar cubes is relevant to:
- Construction industry
- Civil engineers and contractors
- Companies dealing with cement and concrete technology
- Cement testing laboratories
Why should you use BS 4550-6- Standard sand for mortar cubes?
Mortar is a combination of cement and sand mixed with water, that is widely used for masonry works. In this regard, the content of sand plays a crucial role in preventing mortar shrinkage and minimizing risk of cracking during setting. Thus, standard sand can have a marked effect on the water/cement ratio of a mortar mix, which is essential when testing cement performance.
BS 4550-6 provides reference standards for tests to assess the moisture content, grading, and content of acid-soluble matter.
Marking guidelines for the sand are also covered by BS 4550-6.
Thus, compliance with BS 4550-6 on the standard sand for mortar cubes can determine whether its properties are fit for purpose in mortar application, such that it imparts the required compressive strength and workability.
