PORTLAND CEMENT

Product CEM 1 52.5 R/N

STANDARD

EN 197-1:2011


Type G cement is the product obtained by one or more kinds of calcium sulphide with Portland cement clinker as retarder. It mainly consists of hydraulic calcium. It is generally used in structures requiring high early strength, concretes poured in cold weather, prefabricated structures, tunnel-mold practices, production of construction chemicals and foundation concrete works. It is also suitable for use in sea water, as it brings resistance to sulphate ions in areas with a mineralogical structure containing chloride ions


Product CEM 1 42.5 R

STANDARD

EN 197-1:2011


Portland cement; limestone, marl, clay, iron ore, pyrite ash, bauxite, etc.… At appropriate proportions of raw materials, milling, cooking of the clinker obtained, the amount of retarder (generally compose d of a ground with gypsum); It is the product gains strength after a certain time being mixed with water. In general, the structures that requires high strength, cold weather in poured concrete, prefabricated structures, tunnels - in the mold applications, construction chemicals used in the manufacture and application of concrete foundation.


COMPOSITE AND ADDITIVE CEMENT

Product CEM II / A-M (PL) 42,5R

Product CEM II / B-M (P-L) 42,5N

STANDARD

EN 197-1:2011


It is obtained by grinding a certain amount of Portland cement clinker with mineral additives (trass) at proportions CEM II / A-M (PL) 42,5R (maximum 20%) CEM II / B-M (P-L) 42,5N (maximum 30%)and defined in respective standards with reamer (gypsum) and gains resistance by freezing a while after it is mixed with water. It is generally used in all practices where Portland cement is used. Its hydration heat is lower than Portland cement. It is suitable for use in concrete works in aggressive environments containing ions like sulphide and/or chloride.


Product CEM IV/B (P) 32.5 R/N

STANDARD

EN 197-1:2011


It is obtained by grinding a certain amount of Portland cement clinker with mineral (pozzuolana) at proportions (maximum 55%) defined in respective standards with reamer (gypsum) and gains resistance by freezing a while after it is mixed with water. It gains resistance later than portland cement (CEM I 42,5 R and CEM I 52,5 N) and portlandpozzolanic cement (CEM II/A-P 42,5 R). Water/cement rates are also relatively higher. It is more resistant to alkali-aggregate reaction and chemical external factors. It is generally used in repair works in constructions, plastering and production of construction chemicals.


SRC 42.5 R (SULPHATE RESISTING CEMENT)

STANDARD

EN 197-1:2011/TS 10157


SRC 42, 5 R is the product which is obtained by grinding clinker, which is acquired by mixing raw materials like limes tone, marl, clay, iron ore, pyrite ash, bauxite etc. at appropriate rates, grinding and boiling them, with an amount of reamer (generally gypsum) and mixing it with water and which gains resistance by freezing up in a certain time. It may be generally used in areas where normal Portland cements are used and it is also suitable for use in areas exposed to sulphated water like dam constructions, tunnels, port constructions, irrigation channels, construction chemicals as the amount of C3A is below 5%.


OIL WELL CEMENT Class G, MSR and HSR Type

STANDARD

API SPEC Q1 and API SPEC 10 A Type G cement is a product obtained as Portland cement clinker is ground with one or more types of calcium sulphate as retarder. It is primarily comprised of hydraulic calcium silicates. In the production of Type G well cement, no additives should be used other than clinker and calcium sulphate. This type of cement is mainly intended for well cement. Well cement has types such as medium sulphate resistance (MSR) and high sulphate resistance.
