Setting out in surveying is a crucial process in civil engineering projects. It involves transferring the design from plans and drawings to the actual ground, ensuring that the construction work is carried out accurately and precisely. In this blog post, we will explore the fundamentals of setting out, its objectives, methods, procedures, equipment, and benefits….
When designing the structural foundation for a residential or commercial building project, engineers must make key decisions about the supporting concrete beams. Two beam types often confused are grade beams and tie beams. However, each performs very different structural functions in managing loads and stabilizing the building against lateral earth and wind pressures. Understanding the…
The rebound hammer, also known as Schmidt Hammer, is one of the most popular non-destructive testing methods for measuring the compressive strength and quality of concrete and other rigid materials. This handy tool provides a quick, convenient, and inexpensive way to estimate concrete strength in existing structures as well as newly poured concrete. In this…
a) 30%b) 35%c) 40%d) 45% The standard specifies the normal consistency for concrete of grades M55, M60 and M65 as 30-35%, 30-40% and 30-45% respectively. As per Table 5 of IS 10262:2019, the nominal maximum size of aggregate assumed is 20 mm. The normal consistency is defined as the amount of water, expressed as a…
A) Tensile stressB) Compressive stressC) Shear stressD) No stress Explanation: As per theory of thermal stresses, when a body is restricted from free expansion or contraction, it develops internal stresses when subjected to change in temperature. If a constrained part is heated, it tends to expand. But restriction to movement causes development of compressive stresses…
Sieve Analysis is a common method adopted to measure the grain size distribution of an aggregate which is termed as gradation. It is often used in civil engineering and material testing field. This analysis can be done both in fine and coarse aggregates. Aggregates having mean grain size which are less than 4.75 mm are…
