## Vpc concrete and geo technologies calculations of compressive strength

Jun 11, 2021 Compressive strength is defined as the material or the structural tendency to bear or uplift the load applied on it under the action of compression. The compression of a weak material may result into the cracks and fissures which results into failure. Compressive strength = (Max load carried by specimen/Top Surface Area of specimen) Technically

Jun 11, 2021 Calculate the compressive strength of the cube by using formula P/A. Where A is the area of loaded surface (i.e. L B). Repeat the same procedure (steps 9 to 12) for other two cubes. Repeat the whole procedure (Step 9 to 13) to find the compressive strength of the cube at the end of 7 days and 28 days. Observation. For 3 days strength:
