Laboratory of Construction Materials High temperature (~1700 OC) furnace

What is it used for? C3S, C2S, C3A and C4AF synthesis

Solid reaction kinetics

Glass synthesis

Sample during quenching, a mock sampling atroom temperature.

* X.Li, et al. Laboratory synthesis of C3S on the kilogram scale, Cement and Concrete Research, 108 (2018) 201-207; Notes: this protocol was also used to sinter ye’elimite, C3A and C2S

Procedure of the C3S synthesisContour plot of (a) f-CaO and (b) C3S content (%). A sample with ~96 wt% C3S and ~0.3 wt% f-

CaO can be sintered at point P1, P2 or P3 depends on the temperature the furnace can reach

Synthesize C3S on thekilogram scale* Use cast green cylinders - less labor

consuming and increased capacity ofthe Pt crucible

Amorphous silica and reduced PSD ofCaCO3 improved the burnability

Sintering using dried green cylinder in the furnace
