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 stateConcrete modelling to predict crushing in compression, I have seen people modelling the concrete only (in Stadpro) as shell elements, eg in a box bridge beam or concrete stairs Maybe it is not necessary to model the reinforcements! Maybe it is enough to make sure that concrete does not crush in compression (30Mpa) and does not crack in tension (35 Mpa)Compressive Strength of Concrete Cylinders, Apparatus for Concrete Cylinder Test The sample cylinder prepared can be any of the two dimensions as mentioned below The diameter of the cylinder cast must be at least 3 times the nominal maximum size of the coarse aggregate employed in the concrete manufacture The apparatus required is mentioned below: Compression testing machine.
