I appreciate the videos a lot but there was no planeness check using a 0.002in. feeler. This is my main concern and where i feel i needed a walkthrough.
Planeness check is not required on the cylinder if you are capping with unbonded retainers. Note that the retainers do need to be periodically checked to meet the 0.002" planeness but not on every test. Capping with sulfur/gypsum/neat cement has a different procedure which you can see in our video for that test method. Look up our ASTM C617 video and you can see how we check the capped ends with the feeler gauge for that test.
Please make s movie of tensile strentgh of concrete cylinders and with specified strength
Thanks for sharing.
Please what is the height of retainer cup?. Thank you
Standard says 1in, +/- 0.1in
