PVC pipe tensile strength can be measured by hanging weight from the pipe until it bends or cracks. As you can see from the chart to the right, tensile strength of PVC pipe increases as the size of the pipe increases. 8" PVC pipe of either schedule is extremely strong for how inexpensive it is. The smaller sizes are exponentially weaker, but

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.

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. The aggregates passing through 12.5mm and retained on 10mm IS sieves are selected for finding aggregate crushing strength.

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.

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.
