Understanding the Different Types of Walls in Construction
ByN Lavanya Posted onNovember 22, 2023
A wall forms an integral part of any building or structural formwork. Walls serve varied purposes including bearing structural loads; separating interior spaces; providing weatherproofing, fire resistance or acoustic insulation; and forming secure perimeters. Choosing suitable wall types and construction techniques based on precise usage requirements is vital in building design. Modern walls in construction do far…

As per IS 456-2000, what is the maximum free water to cement ratio of an M20 grade reinforced concrete under mild exposure conditions?
ByN Lavanya Posted onNovember 22, 2023
a) 0.50 b) 0.45 c) 0.60 d) 0.55 As per Cl. 8.2.2, Table 2 of IS 456:2000, the maximum free water-cement ratio is specified based on the exposure condition and concrete grade. For an ordinary reinforced concrete of M20 grade under mild exposure condition, this ratio should not exceed 0.55. Therefore, option d) 0.55 is…

If a piece of material neither expands nor contracts in volume when subjected to stress, then the Poisson’s ratio must be:
ByN Lavanya Posted onNovember 20, 2023
A) 0B) 0.25C) 0.5D) 1 According to IS 456:2000, Clause 6.2, Poisson’s ratio is defined as the ratio of transverse strain to axial strain. For a material that does not change in volume under stress, the transverse and axial strains must be equal in magnitude but opposite in sign. Therefore, the Poisson’s ratio for such…

6 Types of Masonry Walls and Their Design
ByN Lavanya Posted onNovember 20, 2023
Masonry walls have been used in construction for centuries owing to their durability, fire-resistance, and aesthetic appeal. Masonry is the building of structures using individual units bonded together with mortar. Masonry walls are constructed by laying masonry units like bricks, concrete blocks, stones, etc. in horizontal layers along with mortar that binds them together. The…
