Such concrete has strength exceeding 40 MPa. High-strength Concrete – High-strength concrete is prepared by decreasing the water-cement ratio to less than 0.35. The strength of this type of concrete is between 10 MPa and 40 MPa There is an initial setting time of around 30 to 90 minutes, depending on the properties of the cement being used and the weather conditions at the site.
Normal-strength concrete – Normal-strength concrete is similar to plain concrete as the same ingredients are used in its preparation.
