- •
Cementitious material was designed according to [SiO4] polymerization degree of raw materials.
- •
The cementitious material composed of calcium silicate slag yields excellent physical and mechanical properties.
- •
Amorphous C–A–S–H gel and rod-like ettringite are predominantly responsible for the strength development.
- •
Leaching toxicity and radioactivity tests show the cementitious material is environmentally acceptable.
