Steel slag retards the early-age hydration of cement. However, the key component which
plays a major role in steel slag is still unclear. In this paper, it was identified that C 12 A 7 in …

Steel slag blended cement exhibits distinctive exothermic behaviors from cement or fly
ash/blast furnace slag blended cement. However, quantitative assessment and prediction …

We studied the formation process of a mayenite structure from hydroxide precursors in
different gas media. According to X-ray diffraction data, this method allows a well-crystallized …

Ladle furnace slag (LFS) exhibits excellent early hydration activity due to its special mineral
component C 12 A 7. The mineral phase of LFS was optimized and modified by rapid air …

The effect of calcination temperature on the structural properties and phase formation of
synthesized CaO-Al2O3 nanopowder was investigated and discussed. The calcination …

Calcium aluminates are attractive materials possessing unique physicochemical properties.
In the present work, three aluminate systems of varied Ca/Al ratio (1/2, 6/7, and 3/2) were …

This study presents a novel approach to activating a binary cementing system composed of
calcium sulfoaluminate (CSA) cement and ordinary Portland cement (OPC) using an instant …

As a byproduct of the secondary refining process, LF refining slag can lead to ecological and
environmental issues such as soil degradation, water pollution, and threats to human health …

Abstract Mayenite (Ca₁₂Al₁₄O₃₃) is an attractive, non-expensive material,
conventionally prepared over 1300° C via solid-state reaction, producing a solid with low …

Aerogel materials attract a growing interest due to their delicate structure and unique textural
properties. However, heat treatment of such materials at elevated temperatures inevitably …
