The strength of cement depends on its grade and type.
The strength of cement is measured in terms of compressive strength.
The grade of cement determines its strength. Higher the grade, higher the strength.
Type of cement also affects its strength. For example, Portland cement has higher strength than lime cement.
The strength of cement is also influenced by factors such as curing time, temperature, and humidity.
