The bulk of the cement industry's environmental burden is from the calcareous source.
Calcium is mostly available naturally as limestone (CaCO 3), where almost half of the mass …

Steel slag inhibits the early-age hydration of cement. However, its mechanism is still unclear.
In this paper, the early-age hydration kinetics and the evolution of the solid phases, aqueous …

The world of stainless steel production was 52 Mt in 2019, and the annual amount of slags
including electric furnace, AOD converter, ladle, and casting tundish, was estimated at 15 …

The utilization of multiple solid-waste-activated slags to prepare clinker-free binders has
garnered considerable interest due to their environmental friendliness and low cost. In this …

High-strength strain-hardening cement-based composites (HS-SHCC) demonstrate
excellent mechanical and durability properties. However, high cement content typical to HS …

The primary obstacle to the widespread adoption of 3D printed concrete technology is the
high carbon emissions associated with the heavy use of cement in the mixture. The main …

Ettringite, as the dominant hydration product in cement materials, plays a significant role in
the solidification/stabilization of heavy metals. However, the combination and immobilization …

Abstract Effects of phosphogypsum (PG) on hydration process and microstructure of the
alkali activated slag (AAS) pastes were discussed in this study, taking the natural gypsum …

Alkali-activated materials (AAMs) shows great potential to be a candidate of ordinary
Portland cement (OPC) when considering the relative lower carbon emission of AAMs. In the …

Supersulfated cement (SSC), mainly composed of solid wastes, is a highly promising low-
carbon binding material, however, the application of SSC is still limited due to inherent …
