Q1. What is cement grade?
Ans. 
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

Q3. The standard size of a concrete cube is 15 cm × 15 cm × 15 cm
Ans. 
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.
