Properties of Bricks – Compressive Strength -Hardness – Efflorescence …

 · 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.

Diamond Drilling vs RC Drilling: Differences and Applications

Diamond drilling is more efficient for precise sampling and analysis, whereas RC drilling is adept at extracting bulk samples. When it comes to speed, RC drilling is the faster method. It can be less accurate than diamond drilling, though – if a quick turnaround is the priority of the drilling project, then RC drilling may be the better ...

Investigation and Improvement of Bursting Force Equations in Posttensioned Anchorage Zone …

 · In posttensioned concrete members, the high local stress under the anchorage causes transverse tensile stress. Therefore, it is very important to predict the bursting force to determine appropriate reinforcement details. In the present work, the existing equations of the bursting force for the anchorage zone were evaluated and an equation for the bursting force …

Concrete Cutting

Concrete bursting is ideal for demolishing mass concrete structures where there are strict limitations on permissible noise and vibration. This method uses hydraulic bursting heads inserted into pre-drilled holes where they develop splitting forces of up to 500 tonnes to crack the concrete, allowing for subsequent removal.

Types of Failures in Beams and Columns

Types of Failures in RCC beams. 1. Flexure Failure. Flexure failure occurs when the imposed loads exceeds the flexural capacity of the structural member. Flexural strength is defined as stress in material just before the yielding starts in flexure test; it represents the highest stress value experienced at moment of rupture.
