Cement performance.

Fineness (%)	SCWC (%)	Stability	Setting time (min)		Flexural strength (MPa)		Compressive strength (MPa)		LOI (%)	MgO (%)	SO3 (%)
			Initial	Final	3 d	28 d	3 d	28 d
4.7	27.2	Aptitude	182	234	6.6	8.7	33.4	54.8	4.7	2.04	2.93

SCWC, standard consistency water consumption; LOI, loss on ignition.
