Common Cement Types Used in TRNC

Portland Composite Cement:

It is obtained by grinding 80-88 and 65-79 unit mass of portland cement with blast furnace slag, silica fume, puzzolan, fly ash, baked schist, limestone and a certain amount of setting regulator  as a gypsum. They are divided into two classes according to the total amount of additives which they contain. Class A includes 12-20 unit mass and class B includes 21-35 unit mass of additives.

Portland Slag Cement:

It is obtained by grinding certain amount of portland clinker and 21-35 or 6-20 unit mass of slag with a little amount of setting regulator  as a gypsum. Due to climatic conditions and island structure of cyprus, portland slag cement is preferable to protect concrete against sulfate, acid attacks and harmful chemicals such as chlorine where cement will use in coastal, port and dock construction, also construction of dams and canals, underground water pipes and in all buildings that may come into contact with sea water. Our company, taking into account the concrete conditions may interact with some harmful chemicals and produce CEM II/B-S 42,5 N type cement for their customers.

Portland Limestone Cement:

Portland limestone cement divided into four classes depending on contains of 6-20 or 21-35 unit mass of limestone amount and the content of calcium carbonate amount in the limestone structure. High percentage of limestone amount ensures fineness to cement hence it provides smoothness on visible surfaces and architectural beauty to concrete. Also, the concrete surface cracks due to the nature of the limestone filler is minimized.

Portland Cement:

According to the standard it is obtained by grinding 95-100 unit mass of portland clinker and a certain amount of setting regulator as a gypsum. Portland cement includes much more than clinker and C3S in its chemistry against composite and slag cements. It is use in Multi-storey concrete structures, bridges, viaducts, such as strengthening the operations building, coating of roads and runways and also in precast concrete constructions.
