crushing strength test; For this 200 gm of cement is blended with 600 gm of regular sand verifying IS 650–1966. Behind mixing completely in a dry disease for a minute purified potable water P 4 + 3 interest is added where P is the water needed for the standard agreement. They are confused with a trowel for 3 to 4 minutes to get a consistent mixture.
The mix is stored in a cube mold of 70.6 mm dimension (Area 5000 mm2) stored on a steel plate and crowded with a 25 mm standard steel rod 20 times in 8 seconds. Then the mold is located on a conventional vibrating table that vibrates at a snap of 12000 ± 400 vibrations through the minute. A hopper is achieved at the top and the surviving mortar is filled. The mold is sounded for two minutes and the hopper raised.
The top is perfected with a knife or with a trowel and smoothed. After 24 ± 1-hour molds are removed, and the cube is placed under clean water for curing. After specified period cubes are tested in a compression testing machine, keeping the specimen on its level edges.
An average of three cubes is reported as crushing strength. The compressive energy at the aspect of 3 days should no be smaller than 11.5 N/mm2 and that at the end of 7 days not less than 17.5 N/milimeters2. Tests on Cement. crushing strength test
