Jan 12, 2019· 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.

1. Scope. This method is for determining the piece crush strength (PCS) of spherical and extruded catalysts using the Lloyd's LS1 motorized sample stand fitted with a load cell. The method applies primarily to particles having a nominal diameter of 1.6-mm (1/16-inch), but may also be used for particles up to 3.2-mm (1/8-inch) in diameter.

Corrugated Comparison Chart. Corrugated material is measured by several factors, including bursting test, edge crush test, combined weight of material, maximum weight of contents, and outer dimensions. Here is a handy chart to compare all of these variables. Please contact Pro Pac or call 888-318-0083 for your corrugated shipping cases.

NOTE: It is expressed in millimetres (mm). 3.6 Crush Strain Change in the diameter of the specimen, in the direction of the compressive load, relative to the gauge diameter. NOTE: It is a dimensionless ratio. 3.7 Modulus of Elasticity Ratio of crush strength to crush strain. NOTE: It is expressed in Newton (N). 3.8 Load-Deformation Diagram

(e) Crush strength determination. Ignore all data prior to 6.4 mm (0.25 in) of crush and after 16.5 mm (0.65 in) of crush. Divide the remaining data into three sections or displacement intervals (n = 1, 2, 3) (see Figure 4) as follows. Interval one is from 6.4-9.7 mm (0.25-0.38 in) deflection, inclusive.

Procedure of Compressive Strength Test on Bricks. Place the specimen with flat face s horizontal and mortar filled face facing upwards between plates of the testing machine. Apply load axially at a uniform rate of 14 N/mm 2 (140 kg/cm 2) per minute till failure occurs and note maximum load at failure.

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.
