Compressive strength of brick in N/mm2 & kg/cm2

Compressive strength/ crushing strength of brick test is calculated by using the equation, F= P/A Where, F= Compressive strength of the brick (in N/mm2). P= Maximum load applied to the brick (in N). A= Cross sectional area of the specimen (in mm2). Compressive /Crushing strength of bricks are very variable, and may vary from 30 kg/cm2 to 150 kg/cm2.

Compressive Strength of Concrete & Concrete

07/07/2016 The strength of concrete is controlled by the proportioning of cement, coarse and fine aggregates, water, and various admixtures. The ratio of the water to cement is the chief factor for determining concrete strength. The lower the water-cement ratio, the higher is the compressive strength.

Compressive Strength of Concrete Cube Test,

18/05/2018 As we all know that concrete is a mixture of sand, cement, and aggregate. The strength of the concrete depends upon many factors like individual compressive strength of its constituents (Cement, Sand, aggregate), quality of materials used, air entrainment mix proportions, water-cement ratio, curing methods and temperature effects.

Compressive Strength of Concrete -Cube Test,

Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures. What is compressive strength after 7 days and 14 days? Compressive strength achieved by concrete at 7 days is about 65% and at 14 days is about 90% of the target strength.

Concrete Block Encyclopedia

The concrete commonly used to make concrete blocks is a mixture of powdered portland cement, water, sand, and gravel. This produces a light gray block with a fine surface texture and a high compressive strength. A typical concrete block weighs 38-43 lb (17.2-19.5 kg). In general, the concrete mixture used for blocks has a higher percentage of sand and a lower percentage of gravel and water
