Break Strength Testing. One of the most common of all testing requirements is the determination of break strength. Break strength is generally the tensile or compressive load required to fracture or to cause the sample to fail. To determine the failure point or break strength, you will need to define what a break is (break detector).

It is probably safe to assume that the minimum crushing strength of well-made blocks, 1 to 5, is 1,000 pounds per square inch at 1 month and 2,000 pounds at 1 year. A block 12 inches wide and 24 inches long has a total surface of 288 square inches, or, deducting ⅓ for openings, a net area of 192 inches.

Modulus of rupture (MOR) is like a three-point bend test. MOR measures the bond strength of the test specimen. For castables, it measures the bonding strength of the cement matrix. The particle size and packing of the aggregate system are factors in MOR, but the maturity of the cement bond contributes more to MOR values.

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.

Compressive Strength of bricks. Generally, bricks have high compressive strength in the range of 5.5 N / mm 2 to 140 N/mm 2. If the crushing strength of the bricks is less than 3.5 N/mm 2 it must not be used. A field test about strength of the bricks is to fall the brick from a height of 1 meter and it must not break in to pieces.

Procedure for crushing strength of aggregate. Before testing, the aggregate should be in surface dry condition.You can achieve the dry condition of aggregate by placing aggregates in an oven for 4 hours at 100-degree Celcius.

It is used to find out the strength of an aggregate sample under a steady, compressive load. The load application must be gradual persistent to allow the sample to deform gradually. The test gives a percentage value called the aggregate crushing value (ACV) which relatively measures the resistance shown by aggregates when crushed under compression.
