Cement and Mineral Additives

Portland cement; limestone, marl, clay, iron ore, pyrite ash, bauxite, etc. at appropria te proportions of raw materials, milling, cooking of the clinker obtained, the amount of retarder (generally composed of a ground with gypsum); It is the product gains strength after a certain time being mixed with water. In general, the structures that require 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.

It is the product that is obtained by grinding Portland cement clinker together with a certain amount of set regulator (gypsum) with additives (limestone) at the rate defined in the standards (min 5% -max 20%) and gains strength by freezing after a certain period of time by mixing with water.

Portland cement is the product, produced by grinding clinker manufactured by burning raw materials like limestone, marl, clay, iron ore, pyrite ash, bauxite at appropriate proportions and by addition of a certain amount of retarder (generally gypsum) and sets and gains strength after a certain time being mixed with water.

It is generally used in works requiring higher strentgh values, concrete works at low temperatures, precast buildings, tunnel-form applications, building chemical manufacturing and foundations.

Additionnaly, it is suitable to be used in sea water . Mineralogical composition of this cement permits to be resistant to sulfate ions in presence of chloride ions.

(1) Cement: It is manufactured to be resistant to sea water according to French standard NF P 15-317. That’s why the “*” sign features; NF P 15-317.

CEM I 42,5 5R-SR5 is the product which is obtained by griding clinker, w hich 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 like dam constructions, tunnels, port constructions, irrigation channels, construction chemicals as the amount of C3A is below 5%.

It is obtained by grinding a certain amount of portland cement clinker with mineral additives (slag) at proportions (maximum 20%) defined in respective standards with rea mer (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.

The cement is produced by grinding a mixture of additives (slag) prescribed by standards (min. % 21, max. % 35) with portland cement clinker by addition of a certain amount of retarder (generally gypsum) and sets and gains strength after a certain time being mixed with water.

Generally the product can be used in all places where portland cement is applicable. Hydration heat is relatively lower than that of portland cement. It can deliver best results especially in concrete works performed in aggresive areas where the content of sulphate and/or chloride is higher.

The cement is produced by grinding at least two types of mineral additive (pozzolana, slug etc.) prescribed by standards (max. %60 in total) with portland clinker by addition of a certain amount of retarder (generally gypsum).

The product delivers the strength values respectively in late periods compared to CEM I and CEM II types. Water/cement ratio is respectively higher. It is much more resistant to alkali and aggretage reactions. It is best for repairing works, foundation filling and used in stucco and building chemicals manufacturing.

Type G cement is the product obtained by grinding portland cement clinker with one or more types of calcium sufates with portland cement clinker. No additives can be used during production of Type G oil well cement except clinker and calcium sulfate This type of cement is aimed to be used as oil well cement basically.

Type G Oil Well Cement has high sulfate-resistant (HSR) and moderate sulfate-resistant (MSR) grades. In Nuh Cement only HSR grade is produced.

The glassy material which is obtained by rapid cooling of the molten slag in the appropriate composition obtained when melting and refining in an iron ore furnace, containing glass slag at least 2/3 of the mass and exhibiting hydraulic properties when properly activated.

Ground granulated blast furnace slag; Fine dust obtained by grinding grain blast furnace slag.
