Testing equipment for the construction industry, SAMOA GEARS UP WITH MODERN TECHNOLOGY FOR CONCRETE CONSTRUCTION AND COMPETITION CHALLENGES - CPI - 4 - 2016 CONTROLS equipment in Western Samoa, the nice and small island state in South Pacific, 4-hour flight north of New ZealandStandard Test Method for Compressive Strength of Concrete ,, 41 Cast-in-place cylinder strength relates to the strength of concrete in the structure due to the similarity of curing conditions because the cylinder is cured within the slab However, due to differences in moisture condition, degree of consolidation, specimen size, and length-diameter ratio, there is not a unique relationship between the strength of cast-in-place cylinders and cores of the ,Compressive Strength of Concrete Cubes, 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 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.
