Abstract
It is now accepted that new binders, such as alkali-activated binders, are needed to replace portland cement for enhanced environmental and durability performance. Alkali-activated binders have emerged as an alternative to (ordinary portland cement ) OPC binders, which seem to have superior durability and environmental impact.This paper reports results of a research project on the development of an alkali-activated binders using mineral waste mud from the Panasqueira tungsten mine in Portugal. Results show that with proper mix design, this new binder presents exceptionally high compressive strength even at early ages. Results also indicate, better abrasion and a...
