How to Calculate Rate of Loading for Concrete Cube Testing Sep 11, 2019· Rate of Loading for Concrete Cube Testing in Compression Testing Machine This is a most interesting question asked by anyone, what is rate of loading for cube testing? Almost all answer it as, Sir as per IS 516 rate of loading is 140 kg / Sqcm / Minute, The load shall be applied slowly without shock and increased continuously until the resistance of specimen (concrete cube) to increasing load A Simple Guide to Concrete Cube TestingNews Spotlight The Safety of Pipelines: Once the cubes have reached failure, the shape of the cube has been altered due to the compression. The failure shape can indicate whether it's a satisfactory / unsatisfactory failure. The image below shows the various failures of a cube as show in BS EN :2009. Specifications.
