2 Analysis of Strength Data 2 1 Definitions Concrete sample a portion of concrete taken at one time from a single batch or single truckload of concrete Single cylinder cube strength or individual strength thestrength of a single cylinder a single cylinder strength doesnot constitute a test result
First ofall we make the concrete cube at some mix proposition as M15 M20 Then after one day the curing on concrete cube 7days or 28days then we findout the compressive strength of concrete The formula for compressive strength is breaking load area of cube
SAMPLING The first step is to take a test sample from the large batch of concrete This should be done as soon as discharge of the concrete commences The sample should be representative of the concrete supplied The sample is taken in one of two ways For purposes of accepting or rejecting the load Sampling after 0 2 m3 of the load has been poured
What would we the effect on strength of concrete block if the cube is casted of size 100x100x100 mm rather than 150x150x150 mm why mm cube is not sufficient to crush the concrete cube

Concrete Testing Laboratory in Qatar There are so many tests available for testing of hardened concrete fresh concrete Slump air content unit weight and compressive strength tests are the most common tests for concrete
According to Wikipedia Compressive Strength of concrete is defined as the Characteristic strength of 150mm size concrete cubes tested at 28 days Why do we test at 7 14 28 days Concrete is a macro content with Sand Cement Coarse aggregate as its micro ingredient Mix Ratio and gains its 100 strength over time at the hardened state
However if the designed concrete strength is 100MPa under the same force about 2 000kN supplied by the machine the stress under a 150mmx150mmx150mm cube is not sufficient to crush the concrete cube Therefore 100mmx100mmx100mm concrete cubes are used instead to increase the applied stress to crush the concrete cubes
If the cube test results show the concrete strength failure that was an awkward moment for an Engineer the criteria mentioned in IS code to accept or neglect the Concrete cube test results For an example If you get the three specimens Crushing Strength Value 20 25 30 respectively Now the average compressive strength value 25 but the
