How we find out the diagonal of a plot What is least count of theodolite Minimum curing days of slab What is M20 M25 M30 Grade of steel etc

Question

Accepted Answer

The diagonal of a plot can be found using the Pythagorean theorem. The least count of a theodolite is the smallest measurement it can make. The minimum curing days for a slab depend on various factors. M20, M25, and M30 are different grades of concrete. The grade of steel refers to its strength.

To find the diagonal of a plot, measure the length and width using a tape measure and then use the Pythagorean theorem (diagonal = √(length^2 + width^2)).
The least count of a theodolite is the smallest measurement it can make. It is typically expressed in seconds or minutes of arc.
The minimum curing days for a slab depend on factors like the type of concrete, weather conditions, and structural requirements. It is generally recommended to cure a slab for at least 7 to 14 days.
M20, M25, and M30 are different grades of concrete used in construction. They represent the compressive strength of the concrete mix after 28 days of curing.
The grade of steel refers to its strength and is denoted by a number such as Fe415 or Fe500. The number represents the yield strength of the steel in megapascals (MPa).

Accepted Answer

Least Count is 20 second. Minimum Curing on Slab is 7 days 'M' is mixture & 20,25,30 is compressive strength which required after 28 days . Grade of Steel 450-550 D
