This invention discloses an eco-friendly concrete cementitious material and eco-friendly concrete, belonging to the field of building materials technology. This invention provides an eco-friendly concrete cementitious material that significantly improves the mechanical properties of eco-friendly concrete through the scientific compounding and synergistic effect of its components. Sulfoaluminate cement, as the main cementitious material, provides early strength and micro-expansion characteristics, effectively compensating for shrinkage. Mineral powder and silica fume, as active mineral admixtures, not only exert a micro-aggregate filling effect, densifying the microstructure of the hardened body, but also consume Ca(OH)2 in the system through a secondary hydration reaction, initially reducing the risk of efflorescence. Gypsum not only regulates the setting time but also promotes the formation of ettringite, improving the strength of the concrete matrix. By adding modified mesoporous silica, the alkali-sealing performance and mechanical properties of eco-friendly concrete can be significantly improved.
