The above test result represents the "Splitting Tensile Strength" of concrete that varies between 1/8 to 1/12 of the cube compressive strength Flexure Test After the Splitting tensile test another common test performed for determination of tensile strength is the Flexure test...

You can either do compressive strength test (done by crushing the cubes) which is highly reliable but takes 28 days to get the results or go for accelerated curing test which gives you approximate value of the compressive strength of cubes in a day...

Beam Bearing on Concrete , The strength of the concrete bearing surface is a function of the plate contact area (NB) Since N is known, this limit state can be solved for B , If B 2 then overhangs the edge of the available concrete, then determine B 2 by the distance to the edge of the available concrete and compute N 2 = N 1 (B 2 /B 1)...
