Read MoreCompressive strength of different grade concrete at 3 days. Calculation: Now concrete cube test by CTM machine,assuming 14N/mm2/minute load is applied on concrete cube specimen of different grade till the cube collapse. The maximum load at which the specimen breaks is taken as a compressive load.
Read MoreTest Procedure of Compressive Strength of Concrete Cubes: There are two types of specimens either cubes of 10 cm*10 cm*10 cm or 15 cm*15 cm*15 cm both depend on the sizes of aggregates used. Commonly size of 15 cm*15cm*15 cm cubical molds are used for most of the works. Concrete is poured and suitably forced so that there will be no voids.

Read More2021-5-14 Compressive strength refers to a material’s or structure’s ability to support pressures on the surface without cracking or deflection. Compression tends to compact material, while stress tends to elongate it. The compressive strength of concrete is known technically as the characteristic strength of 150mm cubes of concrete after 28 days.
