obtained from elastic theory. Strength properties in directions other than parallel (P) or perpendicular (Q) to the grain can be approximated using a Hankinson type formula: where q is the angle to the grain. For bending and tensile strength, N ranges from 1.5 to 2, and for compressive strength from 1.5 to 2.0. For the modulus wood.a

Aggregate Crushing value is a relative resistance of aggregates to crushing under gradually applied compressive load. Aggregate Crushing Value Test is important to test to be performed on aggregate. The strength of aggregate parent rock is determined by preparing cylindrical shape specimens of size 25 mm diameter and 25 mm height.

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.

Compressive (Crushing) Strength. Amount of compressive stress at the onset of failure. The definition of failure tends to vary with material type. As with tensile tests, the terms ultimate and yield can be used. However, ductile materials do not break during compressive testing, and therefore have no ultimate compressive strength.

The Edge Crush Test, which was developed in the 1990’s, measures the stacking strength of corrugated board – how much top to bottom pressure a box can withstand before crushing. Boxes conforming to the Edge Crush Test standard are identified as 32ECT, 44 ECT, etc. Again, the higher the number, the stronger the corrugated box.
