Answer (1 of 3): Compressive strength is the load (measured in pounds/sq. in. or /sq.ft.) which the concrete (poured over a solid base) will support, without damage. Specifically, by being crushed. If the load gets large enough, the concrete will fracture and be crushed. The crush strength is th...

It is also suitable for metallurgy, mining, construction, chemical, water conservancy and railway sectors, and used as a device for fine and medium crushing of ores and rocks with compressive strength below 250 Mpa.


Compressive Strength of Concrete Concrete Cubes What . The capacity of concrete is reported in psi pounds per sq. inch in US units and in MPa mega pascals in SI units.This is usually called as the characteristic compressive strength of concrete fc/ fck. For normal field applications, the concrete strength can vary from 10Mpa to 60 Mpa. Get Price


Concrete being the major consumable material after water makes it quite inquisitive in its nature. The strength of concrete is majorly derived from aggregates, where-as cement and sand contribute binding and workability along with flowability to concrete.. This is an in-depth article on Compressive Strength of Concrete.


The compressive strength of the material would correspond to the stress at the red point shown on the curve. In a compression test, there is a linear region where the material follows Hooke's law.Hence, for this region, =, where, this time, E refers to the Young's Modulus for compression.In this region, the material deforms elastically and returns to its original length when the stress is removed.


if you are checking M30 concrete and you requires min. comp strength of 33n/mm2 and the size of cube is 150mm then the load required to get this much strength is 742.5 Kn. if you use cube of size 300mm the load require becomes 2970 kn, this is practically not possible as to crush the cube u require 3000kn/300 ton capacity machine.


The highest compressive strength of mortar found from stone powder which is 33.02 Mpa, shows that better mortar can be prepared by the stone powder. The compressive strength of concrete from stone ...


The cube can be tested after 3, 7, 14 and 28 days. Cube is placed in compression testing machine and axial load is applied at the rate of 140 kg/ cm2. In actual concrete is required sufficient time to gain strength. Usually 28 days strength is considered as the full strength of concrete.


Compressive Strength Test Idea: 1- Concrete is poured in the mould and compacted properly to reduce the amount of voids. 2- After 24 hours, moulds are removed and test specimens are then placed in water for curing. 3- After the specified curing period [3, 7, 28, 56, or 91 days], specimens are tested by the compression testing machine.


From technical point of view the rich mixes may lead to high shrinkage and cracking in the structural concrete, and to evolution of high heat of hydration in mass concrete which may cause cracking.
