The Advanced Search Space is at its most basic a keyword searching space. The three fundamental techniques in keyword searching are: logical connectors (AND, OR, NOT), term versus phrase searching, and special techniques such as truncation of a term or the insertion of a wildcard character in a term.

بیشترCompressive 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.
بیشترCrushing is done by a moving part, working against a stationary / another moving part. The stresses setup strains within the particle. When the strain exceeds elastic limit, the lump fractures along principle shear stresses into large and fine particles. If the crushing force is not sufficient, no crushing occurs.The material may deform.
