Cement

PORTLAND CEMENT

PORTLAND CEMENT often referred to as ORDINARY PORTLAND CEMENT (OPC) is the most common type of cement in general use around the world because it is a basic ingredient of concrete, mortar, stucco and most non-specialty grout. It is a find powder produced by grinding Portland Cement Clinker, a limited amount of Calcium Sulfate and up to 5% constituents as allowed by various standards such as the European Standard EN 197-1.

Type I/II Portland Cements, which can provide adequate levels of strength and durability, are the most popular cements used by concrete producers. However, some applications require the use of other cements to provide higher levels of properties.

 

Portland Cements ASTM Types

ASTM C 150 defines Portland Cement as “Hydraulic Cement (Cement that only hardens by reacting with water but also forms a water-resistant product) produced by pulverizing clinkers consisting essentially hydraulic calcium silicates, usually containing one or more of the forms of calcium sulphate as an inter-ground addition. Clinkers are nodules of a sintered material that is produced when a raw mixture of predetermined composition is heated to high temperature.

 

Types of PORTLAND CEMENT

ORDINARY PORTLAND CEMENT (OPC)

OPC is the most commonly and widely used type of cement in the world. This type of cement is an ideal building material for almost all structural work including all kinds of concrete construction.

 

SULPHATE RESISTANT CEMENT

SRC is used where sulphate salts are present on the soil or in saline water. This Cement has potential to resist the destructive attack of sulphates, especially in the foundations or the areas mostly subjected to sulphate attack. SRC is designed to overcome the problem of sulfate attack by reducing its C3A content.

PACKING

Cement is exported in Bulk and containerized.

  • Normally cement is exported in 50Kg Bags
  • Jumbo Bags can be arranged on buyer’s request depending upon availability.
