Ramco Cement (Whole sale & Spot Supplying)
Ramco Cement is a PPC grade cement manufactured as per IS 1489 (Part 1):1991.
Ramco Cement is produced either by grinding together Portland Cement clinker and pozzolona with addition of gypsum or calcium sulphate, or by intimately and uniformly blending Portland Cement and fine Pozzolona.
World over Ramco Cement is preferred due to its ability to produce a durable concrete where the life of a concrete structure is given more importance.
Ramco Cement produces less heat of hydration and offers greater resistance to the attack of aggressive waters than normal Portland Cement. Moreover, it reduces the leaching of calcium hydroxide liberated during the setting and hydration of cement.
Ramco Cement 43 Grade (OPC 43):
Ramco Cement OPC 43 confirms to IS 8112. The grade is based on the 28-day compressive strength of the cement mortar (tested as per IS 4031), which in this case is not less than 43 MPa.
Ramco Cement 53 grade (OPC 53):
Ramco Cement OPC 53 confirms to IS 12269. The grade is based on the 28-day compressive strength of the cement mortar (tested as per IS 4031), which in this case is not less than 53 MPa.
Ramco Sulphate Resisting Cement (SRC):
Ramco SRC is manufactured as per IS 12330. This cement is used in marine conditions where soil or water contains excess sulphates. However SRC is weak in resisting chloride attack.
Hence, wherever chlorides are present in combination with sulphates, it is advisable to consider the usage of Ramco Cement after a detailed examination.
The C3A phase of SRC is maintained at lower values <5%.
Sleeper Grade Cement (53 S):
This cement finds its application in the manufacture of precast products and railway sleepers 53 S Cement is manufactured as per IS 12269 where apart from all requirements of 53 Grade, specific requirements in terms of C3A and C3S need to be adhered to. C3A is limited to 10% and C3S is limited to 45%.
