How to Calculate Rate of Loading for Concrete Cube Testing

Sep 11, 2019  Rate of Loading for 15 Cm cube = 308.925 Kn / 60 Sec = 5.148 Kn/Sec Another Example Cube size is 10 cm x 10 cm x 10 cm So total load on this surface area will be 1.373 x 10 x 10 = 137.3 Kn So rate of loading will be = 137.3 / 60 = 2.88 Kn/Sec Same way you can calculate rate of loading for each cube size you test at your laboratory.

Crushing Concrete Cube or Cylinder at 28 days

Apr 01, 2018  The crushing of concrete cubes or cylinder samples is required in a construction especially concrete structures. The reason why this is to verify the strength given in the design mix. Let say for example for a concrete column commonly it has 60 megapascals of specified strength. When you crush it, the result should be equal or more than 60 Mpa. The specified strength should be achieved at

Compressive Strength Test Of Concrete Detailed Guide

Simple. Assume, the approx weight of one concrete cube = 8 kg Then the volume of concrete = 0.15 x 0.15 x 0.15 = 0.0033 m 3; So for 1 m 3 = 8/0.0033 = 2400 kg/ m 3. Since the concrete weight itself has also been assumed for the structural calculations, if it exceeds the assumed value, then the load on the structure will likely increase.
