M25 is a grade of concrete with a compressive strength of 25 megapascals after 28 days of curing.

• M25 is a mix of concrete with a ratio of 1:1:2 (cement:sand:aggregate).

• It is commonly used for residential construction, pavements, and small-scale projects.

• The strength of M25 concrete is achieved after 28 days of curing.

• It is important to follow proper mixing and curing procedures to achieve the desired strength.

To make a BOQ for larger construction work, one must accurately estimate quantities of materials and labor required for each aspect of the project.

• Break down the project into smaller components such as foundation, superstructure, finishes, etc.

• Calculate the quantities of materials needed for each component based on the project drawings and specifications.

• Estimate the labor hours required for each component based on the...read more
