Test 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.
17-04-2020· Using 7.07 cm x 7.07 cm x 7.07 cm mortar cubes with sand to cement proportion of 1:3 where the sand should be standard as specified in IS:650 as fine aggregate, compressive strength of cement could be indicated after 28 days curing. The following formula was used to determine the compressive strength for cement: Stress=P/A. Where, P= Applied load.
