OKETON MOD 1223 K is modified lignosulfonate based, water reduction, standard plasticizing (improves concrete flow properties) concrete admixture designed to provide fast hardening of concrete in cold weather conditions, to improve application quality and mechanical features by decreasing water/cement ratio. Conformance code: 04.613/1-А2 The product conforms to the requirements of the AZS 221-2006 (TS EN 934-2) standard, Table 2: “Water reduction, plasticizing (improves concrete flow properties) concrete admixture”, and ASTM Type A standard: “Water reduction and plasticizing concrete admixture”.

This concrete admixture can be applied in the following areas:

• Production of concrete designed for application with or without pumps;
• Production of all grades of concrete, reinforced or non-reinforced, for low or standard loads;
• Production of all grades of concrete which requires fluid viscosity.

• Reduces amount of water at least by 5%-12% compared to admixture-free concrete;
• Increases resulting strength compared to admixture-free concrete;
• Provides easy pumping enhancing the product quality at low water/cement ratios compared to admixture-free concrete;
• Can be used for different purposes;
• Due to combination of lower effect of a standard plasticizer, and higher effect of a super plasticizer, it reduces the general necessity of multi-type admixtures;
• Provides higher strength and lower water penetration due to low water/cement ratio;
• Provides easy application of concrete and reduces the risk of disintegration;
• Creates uniform surface of concrete in formwork without disintegration;
• Facilitates establishing frame type connections;
• Does not contain chlorine.

Preparation of the mixture. Mix the mineral adhesives (cement, quartz sand, volcanic cinders, slag) with concrete filler until the mixture is entirely homogeneous. After 50-70% of the total required water amount is added, start to add the OKETON MOD 1223 К product together with the remained amount of water to the mixture.  To provide homogeneous composition of OKETON MOD 1223 K mixture mix it vigorously during 60 seconds or during time period predefined based on the laboratory test results.

Chemical admixtures reaction principle. The admixtures react mainly with adhesives. When the admixture is added to the concrete it is absorbed by the adhesive particles. The adhesive particles are repelled from each other under the effect of electrostatic force. Thus, the smaller amounts of water provide the required application conditions. The concrete mechanical strength increases proportionally to the reduction of water content in the mixture.

Compatibility to other admixtures .OKETON MOD 1223 K can be used together with the following materials:

• All grades of cement;
• Quartz sand, volcanic cinders and slag, when application of large amounts of adhesive substances is required;
• To increase resistance to freezing and melting, it can be used together with the AntiAir 250 air entraining additive;
• To prevent formation of cracks due to plastic compression, it can be used together with synthetic and steel fibers;
• To prevent water vaporization from mixtures in the concrete composition, and to increase the concrete strength in the areas of hot climate and high air velocity the product may be used together with corresponding moisture-retaining products, like MA Kur 100, MA Kur 200 and MA Kur 300;
• To accelerate hardening by increasing of the concrete hydration temperature in cold weather conditions it may be used together with the OKETON 1260 CN product;
• To increase the concrete viscosity at the construction site it may be used together with the OKETON MOD N concrete additive.

The parameters have been received at the +200C temperature and 50%  humidity.

It is recommended to add the OKETON MOD 1223 K product in proportion of 0.4-1.2% to the cement amount. Depending on the concrete type and characteristics, the actual amount of admixtures should be defined based on preliminary laboratory tests.

OKETON MOD 1223 K may be stored in original packing in the areas with ambient temperature equal to or above +50C. The product stored in unsuitable conditions and exposed to freezing temperatures should be melted at room temperature without adding water, then it should be mixed using mechanical methods till it is entirely homogeneous. When mixing compressed air should not be used.

Under the required storage conditions, the product may be stored during 12 months from the manufacturing date. The product in open containers should be used within the storage period provided the cap is kept closed.

• when using the product observe regulations of operational and personnel safety, wear appropriate protective clothing, safety gloves, glasses, and respirators;
• taking into consideration that the product can cause allergic reactions and itch, take care to avoid contact of its components with skin or eyes, otherwise immediately rinse them with large amount of water and wash with soap;
• in case you swallow the product, immediately consult a physician;
• do not keep food in the areas of the product application;
• keep the product away from children;
• mix the fine or coarse concrete fillers with mineral adhesives according to the results of laboratory researches (cement, quartz sand, volcanic cinders, slag) till the mixture is completely homogeneous. In case the admixture is added to the dry mixture without water, it will be absorbed by the mixture and will result in forming irregularities when applied. Even if you add water afterwards to such improper mixture, the required type and characteristics of concrete will not be achieved. In case water is added to the mixture in larger amounts than required this will unbalance the required design factors of the concrete, and mechanical features of concrete will be deteriorated. Taking into consideration the mentioned above, the concrete admixtures should not be added directly into dry mixture without water;
• amount of admixture in the mixture composition is calculated as the sum of weights of cement and adhesives (quartz sand, volcanic cinders, slag) multiplied by the coefficient of 0.8-1.4% of the cement amount;
• in case the amount of product added exceeds the recommended value, the mixture hardening period may increase. In these cases it is necessary to provide the required longer curing time for concrete hardening in the reinforcement structures .
