ASTM C617/C617M Standard Practice for Capping Cylindrical Concrete Specimens
ASTM C617 is the standard practice for capping cylindrical concrete specimens before compressive strength testing. To match this to your program, talk with our team.
What ASTM C617 Covers
It covers the materials, apparatus, and procedures used to create plane, parallel bearing surfaces on concrete cylinders so load is applied uniformly.
How the Test Is Run
A capping compound or sulfur mortar is applied to the cylinder ends to form flat, parallel bearing surfaces before the specimen is loaded in compression.
Why It Matters
Proper capping ensures uniform load transfer and valid compressive results; a capping setup and a high-force compression machine are used together.
