PROJECTS

MAIN PRODUCTS

1-) Cement: Cement is a glue which acts as a hydraulic binder. It is primarily used to bind fine sand and coarse aggregates together in concrete.

There are 27 types of common Cement which can be grouped into 6 general categories and 3 strength classes: ordinary, high and very high. In addition, some special Cements exist like sulphate resisting cement, low heat cement and calcium aluminate cement.

The most commonly used cement types for general construction work are:

Ordinary Portland Cement (OPC): 32.5, 42.5, 52.5 grade (OPC)
Portland Pozzolana Cement (PPC): Both Fly Ash and Calcined Clay based
Portland Slag Cement (PSC)
White Cement

2-) Clinker: Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties.

The most commonly used clinker types for cement production work are:

Clinker to be used on Portland Cement and its blends
Sulphate Resistant Clinker
Low Heat Clinker
White Clinker
Low-alkali Clinker
Belite Calcium Sulfoaluminate Ternesite (BCT)

3-) Cementitious Materials: Those are the materials that may be used as part of cements. When added at the concrete mixing plant such SCMs are referred to as ‘cementitious additions’ as they are added to high clinker CEM I or CEM II/A cements. They may be naturally occurring with minimal processing or may arise from wastes or by-products from other industries. Principal cementitious materials in cement industry are

Fly Ash
GGBFS (Ground Granulated Blast Furnace Slag)
Natural and Artificial Limestone
Natural and Artificial Gypsum
Pozzolana
Dolomite
Kaolin Clay

4-) Solid Fuels: They refer to various forms of solid material that can be burnt to release energy, providing heat and light through the process of combustion.

Main solid fuel types used in the cement production kilns are;
