Durability of concretes containing natural pozzolan

Proceedings of the Institution of Civil Engineers - Construction Materials, 2008
In this study, the effects of tuff natural pozzolan on properties of Portland cement were investigated. The durability and mechanical properties of concrete made by these cements were studied. It was found that using the natural pozzolan does not significantly affect the mechanical properties of the Portland cement.
