CUBE TESTING #civilengineering

Casting of cubes 15 cm size cubes shall be cast on a vibrating table conforming to IS: 2514 from random samples spread over the entire lot, out of concrete used for casting sleepers for testing prior to transfer of prestress and 15 days.
Method of testing The cubes shall be surface dry at the time of testing.
The rate of loading shall be about 400 KN/minute.
. The samples should be spread over the entire period of concreting in a lot. Cubes of these samples shall be tested for 15 days compressive strength of concrete. The shall be the average of the strength of three cubes. Individual variation in cube strength in a sample should not be more than ±15% of the average. If variation is more than ±15%, the test results of the sample is invalid and the lot shall be rejected.
