Active Iron-Rich Belite Sulfoaluminate Cements: Clinkering ...

Ordinary Portland cement (OPC) is an environmentally contentious material, as for every ton of OPC produced, on average, 0.97 tons of CO2 are released. Conversely, belite sulfoaluminate (BSA) cements are promising eco-friendly building materials, as their production may deplete CO2 emissions up to 35% (compared to OPC).

Synthesis and hydration of alite-calcium sulfoaluminate .

The cement showed a very short setting time. Moreover, it gave higher early strength than PC at 1 and 3 d and showed expansive properties. The heat of hydration of this cement after 72 h was higher than for PC. The main crystalline hydration products found were ettrin-gite and portlandite. Additionally, the hydration of three different ACSA cements

A pilot-scale trial was undertaken in a 74 m kiln to demonstrate the production of belite calcium sulfoaluminate cement clinker using sulfur as a raw feed. The sulfur was introduced in its elemental form as fuel to the burner, thus partially offsetting fuel costs while providing sulfur trioxide which is incorporated in the clinker.
