Alternative Cement substitutes materials - Constro Facilitator

Chemically it is similar to, but less reactive than, Portland cement (Pc). When mixed with water it will hydrate in a similar way to Portland cement. It is always used in combination with Portland cement, typically in the range 60% Pc and 40% GGBS – 30% Pc and 70% GGBS, according to the ultimate function of the cement.

Influence of Glass Powder on Rheological Properties of

Replacing cement and silica fume with glass powder to prepare ultra-high performance concrete (UHPC) is beneficial to solve the ecological problem in the field of civil engineering, but the technologies of preparation, transportation, pumping, and hardening of UHPC mainly relate to its rheological property. Therefore, this paper studied the influence of glass powder on the rheological
