Chetan Sharma, Corporate Trainer of Civil Guruji, is Explaining About How to Use the Compressive Strength Testing Machine for Concrete Cube Test Apparatus As per IS: 516-1959 Compressive testing machine (2000Kn),15cm×15cm×15cm steel cube molds or Cylinder having Dia 15cm and length 30cm are used. Preparing of material for Cube test: All the material must be brought and stored to an approximate temperature of 27 ±3 degree Celsius. Cement must be uniformly mixed with a trowel in order there exist no lumps. Mixing of concrete: Machine mixing: The ingredient must not be rotated for more than 2 minutes and the following pattern must be followed Casting of specimen The casting molds are chosen to be made of cast iron and must be rubbed with grease on inner side for easy removal of cubes. The specimen must be cast in 3 layers (5cm each) and properly compacted in order that honeycombing formation does not take place. Compaction In compacting through tamping bar, 35 strokes must be done in all parts of a cube for proper compacting. This tamping bar has the dimension of diameter 16mm and length of 0.6m. How to Use the Compressive Strength Testing Machine for Concrete Cube Test Age of test The cube test for Compressive strength can be done on 1,3, 7, 14 and 28 days. In some cases, the strength of greater ages is required which is performed from 13 to 52 weeks. How to Use the Compressive Strength Testing Machine for Concrete Cube Test Number of specimens It is mandatory to have at least 3 specimens for testing from different batches. The mean of compressive strength achieved by this specimen is used to determine actual strength of the batch. How to Use the Compressive Strength Testing Machine for Concrete Cube Test Procedure for Compressive strength of concrete or Cube test :- Place the prepared concrete mix in the steel cube mould for casting. Once it sets, After 24 hours remove the concrete cube from the mould. Keep the test specimens submerged underwater for stipulated time. As mentioned the specimen must be kept in water for 7 or 14 or 28 days and for every 7 days the water is changed. How to Use the Compressive Strength Testing Machine for Concrete Cube Test Ensure that concrete specimen must be well dried before placing it on the UTM. Weight of samples is noted in order to proceed with testing and it must not be less than 8.1Kg. Testing specimens are placed in the space between bearing surfaces. Care must be taken to prevent the existence of any loose material or grit on the metal plates of machine or specimen block. The concrete cubes are placed on bearing plate and aligned properly with the center of thrust in the testing machine plates. The loading must be applied axially on specimen without any shock and increased at the rate of 140kg/sq cm/min. till the specimen collapse. Due to the constant application of load, the specimen starts cracking at a point & final breakdown of the specimen must be noted.
