As per most codes of practice, concrete strength is expressed as the characteristic strength, i.e. not more than 5% of test samples will fall below this value of strength. In the Indian Code IS: 456, strength is expressed as the characteristic str...
The concrete is usually sampled after the 1 st metre of concrete has been poured to ensure a good sample is taken. As said in BS EN 12350-1, take a few samples throughout the pour for the best representation of the batch and make sure you take 150% of what you think you'll need.
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 strength over time at the hardened state.

The BPDA structural design calculator simplifies concrete pipeline design calculations based on the recommendations in BS EN 1295-1 "Structural design of buried pipelines". The Structural design calculator offers all the basic values; from external design loads (W e ), to bedding factors (F m ) taking into account the pipe crushing strength (F n ).
Dec 15, 2008· I did a cube crushing test in an experiment and for my two cubes i got the results of 29.84 KN and 24.19 KN now i need to work out the compressive strength compressive strength (N/mm^2) = maximum load / cross sectional area the dimensions of the cube was 100m x 100m x 100m I have to compare these with some set results that came out will compressive strengths of 50 - 37 however mine is coming ...
When the load reached 85 kN, a compression failure occurred with crushing of the concrete at the top of the beam, then the load dropped until bar rupture and complete collapse of the beam took place at a load of 65 kN. The expected bar rupture as a mode of failure did not occur.
