Hardness test is also carried out in Dorry's testing machine. 2. Crushing test. Three cube samples of size are cut and placed in water for 72 hours. They are tested in crushing test machine with loading 13.7 N/mm 2 per minute. 3. Transverse strength test
The specimens were tested using the Tonipact-3000 (cube crushing machine), with a loading rate of 0.2 N/mm 2 /s. The top loading plate of the machine is initially free to level with the test specimens (up to 5 kN load), then locked automatically to minimise the effect of load eccentricity.

CONCLUSION The observed Zero slump (shape-b.) is the indication of very low water-cement ratio and it is occurring because of dry mix. The compressive strength of concrete test cube, cylinder and lintel has been determined in the 7th day after making the test. For the average compressive strength of 7th day concrete test cube is 4.63 MPa.

The cubes should be covered with a damp cloth and a plastic sheet and stored in dry environment at a temperature range of 20 ± 5 degrees. The concrete cubes are removed from the moulds between 16 to 72 hours, usually this done after 24 hours. Make sure the cube ID is transferred to the cube from the mould before placing into a curing tank.
and the results, obtained from these analyses, can be cited with a high confidence level. As shown by Wang (2005), theoretical investigations and extension of numerical methods on PLT are rapidly increasing and including the latest research by the comprehensive research, in which a field test was modeled by ABAQUS software.
Tensile Test. One can do a very simplified test at home. If you have a way to hang one end of some material from a solid point that does not move, then you can hang weights on the other end. Measure the change in length while adding weight until the part begins to stretch and finally breaks.
