Neocrete Technologies Interview Questions and Answers

Grades of concrete refer to the strength of the concrete mix.

• Concrete grades are denoted by M10, M20, M30, etc.

• The number after 'M' represents the compressive strength of the concrete in N/mm² after 28 days of curing.

• Higher grade concrete is used for structures that require higher strength, such as bridges and high-rise buildings.

Material requirements for a work can be calculated by multiplying the area of the work with the required thickness of the material.

• Calculate the area of the work in square meters

• Determine the required thickness of the material in meters

• Multiply the area with the thickness to get the material requirements in cubic meters

• Consider any wastage or additional material required for the work

The material used in concrete is crucial for its strength, durability, and overall performance.

• The type and quality of aggregates, cement, and water used affect the properties of concrete.

• Aggregates should be clean, strong, and durable to ensure good bonding with cement.

• Cement should have the right chemical composition and fineness to provide strength and durability.

• Water-cement ratio should be optimal to ensure good w...read more
