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…
A lintel is a critical component in building construction that requires careful design and detailing to ensure structural integrity. This comprehensive guide covers everything you need to know about lintel construction. What is a Lintel? A lintel is a horizontal structural member that spans over an opening like a window or door to carry loads…
The project life cycle represents the various stages involved in constructing infrastructure and buildings. Understanding the project life cycle is key for civil engineers to deliver projects on time and budget. This guide examines the major phases of a construction project life cycle. Stages of the Construction Project Life Cycle The project life cycle for…
A) ToughnessB) Proof ResilienceC) DuctilityD) Malleability According to IS 800:2007, Clause 2, Proof resilience is defined as the maximum strain energy that a material can absorb per unit volume without any permanent deformation. This is an important design consideration as it indicates the ability of a material/component to absorb shock and impact loads by undergoing…
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…
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…
