Objective For determination of compressive strength of bricks Reference Standard IS: 3495 – P (1)-1992-Methods of tests of burnt clay building bricks (Determination of compressive strength) Equipment & Apparatus Compression Testing Machine Scale for measuring dimension of brick Procedure Unevenness observed in the bed faces of bricks …
Compressive Strength of Brick Masonry A wall or column carrying a compressive load behaves like any other strut, and its loadbearing capacity depends on the compressive strength of the materials, the cross-sectional area and the geometrical properties as expressed by the slenderness ratio (see Fig. 1).
Compressive /Crushing strength of bricks (Indian Made) are very variable, and may vary from 30 kg/sq. cm to 150 kg/sq. cm for hand-made burnt bricks, while Crushing strength of heavy duty bricks machine pressed (also called engineering bricks) may have compressive strength as high as 450 kg/sq. cm, and even 500 kg/sq. cm.
ABSTRACT. Data on cold crushing strength in three directions, viz., flat, edge, and endwise of six brands of fire brick are given.Transverse strength data of all these brands are also given. Porosities of all the brick used in these tests were determined by the air-expansion method.
Engineering bricks are either Class A or B, the bricks that are sold the most are Class B bricks, which are the cheapest engineering bricks. They are generally red in colour, and less uniform than facing bricks. Class A bricks have a strength of 125N/mm² and water absorption of less than 4.5%, and Class B
