Compressive strength of concrete is its ability to resist compression or withstand loads that tend to reduce its size.

• Compressive strength is measured by applying a compressive load to a concrete cylinder or cube until failure occurs.

• The strength of concrete is affected by factors such as water-cement ratio, curing conditions, and aggregate type.

• The compressive strength of concrete is important in determining the load-...read more
