Are pozzolans all alike?

Q. Are pozzolans all alike?

 

A. No. It is therefore important to make sure that a proposed pozzolan meets the specification requirements and is particularly capable in any specific respect desired, such as reduction in expansion from the alkali-silica reaction or reduction of the rise in temperature.
