BS EN 12350-2:2019 - TC

What is BS EN 12350‑2-Slump test for testing fresh concrete about? 

BS EN 12350‑2 is the second part of the multi-series standard which discusses the slump test for testing fresh concrete. 

BS EN 12350‑2 specifies a method for determining the consistency of fresh concrete by the slump test. The slump test is sensitive to changes in the consistency of concrete, which correspond to slumps between 10 mm and 210 mm. Beyond these extremes, the measurement of slump can be unsuitable and other methods of determining the consistency should be considered. 

Note 1: The test is not suitable when the declared value of D of the coarsest fraction of aggregates used in the concrete (Dmax) is greater than 40 mm. 

Note 2: If the slump continues to change over 1 min after withdrawing the cone, the slump test is not suitable as a measure of consistency. 

Who is BS EN 12350‑2-Slump test for testing fresh concrete for? 

BS EN 12350‑2 on slump test is applicable for: 

• Companies dealing with testing the concrete with a slump 
• Civil engineers/contractors 
• Construction companies  

Why should you use BS EN 12350‑2-Slump test for testing fresh concrete? 

The concrete slump test is used to measures the consistency of fresh concrete before it sets. The concrete slump is performed to check the workability of freshly made concrete, and therefore the ease with which concrete flows. 

BS EN 12350‑2 gives you the principle of fresh concrete which is compacted into a cone. When the cone is withdrawn upwards, the distance the concrete has slumped provides a measure of the consistency of the concrete.  

What’s changed since the last update? 

BS EN 12350‑2:2019 supersedes BS EN 12350‑2:2009, which is withdrawn. It includes: 

• Editorial revisions 
• Reference to common apparatus and specifications given in EN 12350-1 
• Reference and procedure for slump retention testing 
• Option to include specified slump class or slump target value in the report
