· Apply axial load continuously and without shock until the load becomes constant, reduces, or a predetermined amount of strain is achieved. Apply the load in such a manner as to produce either a stress rate or a strain rate as constant as feasible throughout the test. Do not permit the stress rate or strain rate at any given time to deviate by more than 10 percent from .

Take out the cubes from water just before testing. Testing should be done on their sides without any packing. The rate of loading should be 350 kg/cm 2 /minute and uniform. Test should be conducted for 3 cubes and report the average value as the test result for both 7day and 28 day compressive strength. Result of Mortar Cube Test

When tested under Load Rate II, the rate of load applied to the cube is controlled by movement over time. ASTM C 109 requires that the load applied to the cube is controlled by stress over time. The loading rates in ASTM C109 and ASTM C 579 are different and may produce considerably different compressive strength results. ASTM C 579 does not address the testing of nonshrink (expansive ...

effect of rate of loading on the compressive strength of mortar cubes. Three loading rates were used, 1000, 3000, and 6000 psi per minute. The results varied considerably, some cements showing an increase in strength with increased rate of straining and others showing a decrease in strength. The average of all

Then the crushing strength is obtained as load divided by crosssectional. ... • After 24 hours, remove the cubes in the mould and immediately submerge in clean water till testing. • Take out the cubes from the water just before testing.
