What Are the Different Grades of Concrete? | Reference.com

Any type of concrete that is rated higher than 6,000 psi is considered to be high-performance concrete. This grade is typically set aside for heavy-duty commercial projects, although special projects such as skyscrapers can require concrete that has a grade of at least 10,000 psi.

Concrete - Wikipedia

Concrete, usually Portland cement concrete (for its visual resemblance to Portland stone), is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens over time—most frequently in the past a lime-based cement binder, such as lime putty, but sometimes with other hydraulic ...

CONCRETE MIXING RATIOS - Everything About Concrete

The less water you use to mix the concrete (somewhat dry but workable) the stronger the concrete mix. Accurate concrete mixing ratios can be achieved by measuring the dry materials using buckets or some other kind of measuring device. By measuring the mixing ratios you will have a consistent concrete mix throughout your entire project.
