The 40 is the compressive requirement of 40 nmm of a crushed 100m concrete core and the 50 is a compressive requirement of 50 nmm for a crushed concrete cube therefore using the method of testing using concrete cubes the tested compressive strength should be
Testing of cube samples concrete cube samples area tested on compression testing machine after 7 days curing or 28 days curing the application load is gradua at the rate of 140 kgcm2 per minute till the specimens fails the compressive strength of the concrete cube is the load applied at the point of failure to the crosssection area of the
5 methods for onsite evaluation of concrete extracting concrete samples read more challenges of concrete coring and testing for compressive strength is often considered the most costeffective and most reliable fact many codes and guidelines consider this the only approved method for evaluating concrete strength

This study considered the effect of different methods of curing on density and compressive strength of concrete concrete cube spec imens of mix 12 4 were prepared w ith watercement r atio of 065
Although indicative strength can be achieved by testing the cubes after 3 days 50 of 28 days strength and 7 days 60 of 28 days strength from casting a more standard method is commonly called accelerated curing test accelerated curing is a method used to get high early compressive strength in concrete structure
In order to get a relatively quicker idea of the quality of concrete optional test for 7 days compressive strength of concrete be carried out 6 cubes of 150 x 150 x 150 mm size the nominal size of aggregate does not exceed 38 mm shall be cast 3 for 7days testing and 3 for 28days testing
May 10 2013 objective the tests are required to determine the strength of concrete and therefore its suitability for the job reference standards is 5161959 methods of tests for strength of concrete equipment apparatus compression testing machine 2000 kn curing tankaccelerated curing tank balance 010 kg procedure representative samples of concrete shall be taken and
B flexural strength when both the following conditions are met the concrete complies with the specified flexural strength a the mean strength determine from any group of four consecutive test results exceed the specified characteristic strength by at least 03 nmm 2 b the strength determined from any test result is not less than specified characteristic strength less 03 nmm 2

Accelerated curing method is used to get early high compressive strength in concrete this method is also used to find out 28 days compressive strength of concrete in 28 hours as per is 90131978method of making curing and determining compressive strength of accelerated cured concrete test specimens ad free
Compressive strength of concrete concrete cubes the pressive strength of concrete is given in terms of the characteristic pressive strength of 150 mm size cubes tested at 28 days fck the characteristic strength is defined as the strength of the concrete below which not more than 5 of the test results are expected to fall get price
For that matter a certain quantity of concrete shall be cast as a cube while concrete pouring time to find the compressive strength of that concrete batch the cube will be preserved and curated well for almost 28 days to be tested by the compression testing machine compressive strength of concrete test
