LTIMindtree Civil Site Engineer Interview Questions and Answers for Freshers

Cement grade refers to the strength and quality of cement used in construction.

• Cement grade is determined by the compressive strength of cement mortar cubes after 28 days of curing.

• The most commonly used cement grades are 33, 43, and 53, indicating their respective compressive strengths in megapascals (MPa).

• Higher cement grades are used for structures that require higher strength, such as bridges and high-rise building...read more

Yes, the standard size of a concrete cube is 15 cm × 15 cm × 15 cm.

• The standard size of a concrete cube is used for testing the compressive strength of concrete.

• The cubes are casted and cured for 28 days before testing.

• The cubes are tested using a compression testing machine.

• The compressive strength of concrete is calculated by dividing the maximum load applied to the cube by the cross-sectional area of the cube.
