If condition Equation 2–5 is not satisfied and the default values shown in Equation 2–2 thru Equation 2–4 are assumed, the strength of the concrete material may be incorrectly evaluated. When the crushing capability is suppressed with f c = -1.0, the material cracks whenever a principal stress component exceeds f t.

202472· Masonry prisms and wallettes were tested in the former direction, whereas only wallettes were tested in the latter direction. No influence of mortar strength or block thickness was observed on the cracking and failure patterns of specimens of similar type, although material crushing and spalling was marginally influenced by block strength.

If a section is made up of more than one concrete material, the entire section is designed using the concrete properties of lowest strength in that section. Rectangular concrete stress block with maximum stress equal to 0.85f’c and the depth of stress block from the extreme compression fiber, a, equal to β1c is used. See Fig. 2

This standard was first published in 1962 and subsequently revised in 1967 and 1979. The second revision was published under the modified title ‘Specification for concrete masonry units: Part 1 Hollow and solid concrete blocks’. Also Part 2 and Part 3 were brought out, Part 2 covering lightweight concrete masonry units as revision of IS 3590: 1966’ Specification for load bearing
