The OPC data block contains information on the composition of OPC clinkers in terms of weight percentages of the different oxides.



The data block contains following columns


Name

Unique identifier of the OPC oxide composition. The name appears in linked drop down lists in input tables, e.g. Cement::Clinker::Reference$ in the OPC Clinker group of ModuleCement_Input_02_Recipe table.

Unit

Defines the used unit. Only mass% (i.e. g/100 g OPC clinker) is valid. Not used.

BulkDensity

Bulk density of the OPC clinker in kg/dm³.

CaO

The mass percentage of CaO in the OPC cement.

SiO2

The mass percentage of SiO2 in the OPC cement.

Al2O3

The mass percentage of Al2O3 in the OPC cement.

CO2

The mass percentage of CO2 in the OPC cement.

SO3

The mass percentage of SO3 in the OPC cement.

Fe2O3

The mass percentage of Fe2O3 in the OPC cement.

MgO

The mass percentage of MgO in the OPC cement.

Na2O

The mass percentage of Na2O in the OPC cement.

K2O

The mass percentage of K2O in the OPC cement.
