Stirrups cutting length for columns 400x500 can be calculated using a formula based on column dimensions and spacing.

• Calculate the perimeter of the column (2x(400+500))

• Determine the spacing between stirrups

• Use the formula: Stirrups cutting length = Perimeter + 2x(cover thickness) - 2x(hook length) + 10d - 5d

• Substitute the values to find the cutting length

Grade M-30 is a designation for concrete mix with a compressive strength of 30 megapascals after 28 days of curing.

• M-30 is a mix of concrete with a compressive strength of 30 megapascals.

• It is commonly used in construction for structural elements like beams, columns, and slabs.

• The designation M-30 indicates the ratio of cement, sand, and aggregates in the mix.

• The strength of M-30 concrete is achieved after 28 days of c...read more

Grade M-25 is a type of concrete mix design used in construction.

• Grade M-25 refers to the mix design of concrete where M denotes mix and 25 denotes the compressive strength of concrete in N/mm^2 after 28 days of curing.

• It is commonly used in construction for residential buildings, bridges, and pavements.

• The mix proportion for Grade M-25 concrete is 1:1:2 (cement:sand:aggregate).
