Types of concrete - Wikipedia

High-strength concrete has a compressive strength greater than 40 MPa (5800 psi). In the UK, BS EN 1 defines High strength concrete as concrete with a compressive strength class higher than C50/60. High-strength concrete is made by lowering the water-cement (W/C) ratio to 0.35 or lower.

What's the Difference Between Cement and Concrete?

Through a process called hydration, the cement and water harden and bind the aggregates into a rocklike mass. This hardening process continues for years meaning that concrete gets stronger as it gets older. So, there is no such thing as a cement sidewalk, or a cement mixer; the proper terms are concrete sidewalk and concrete mixer.

PROPERTIES AND MIX DESIGNATIONS

durable concrete. A low w/c ratio is a good indicator of durable concrete. A general characteristic of a low w/c ratio is that an acceptable strength is usually inherent. The overall voids left in the concrete by excess water are kept to a minimum by keeping the batch water and any add water to a minimum.
