FLOTON MOD N is modified lignosulfonate based, plasticizing concrete admixture, used to provide fluid viscosity in production of concrete designed for civil works in all types of climatic conditions and different concrete categories. The product conforms to the requirements of the AZS 221-2006 (TS EN 934-2) standard, Tables 3.1 and 3.2: “High water reduction, latest generation super plasticizing (improves concrete flow properties) concrete admixture”, and ASTM C 494 Type F standard: “High water reduction, latest generation super plasticizing concrete admixture”.

This concrete admixture can be applied in the following areas:

• Production of concrete with required improvement of viscosity properties at the construction sites located at short or long distances (concrete to be transported to short or long distances);
• In cases prefabricated concrete has low viscosity, while higher viscosity is required at the place of application;
• In cases faster application of concrete is required at the construction sites and in the areas where faster completion of works is required.

• Increases the concrete viscosity at the construction sites averagely by 6-8 cm;
• Increases the concrete viscosity when viscosity adjustment is required due to loss of viscosity during concrete transportation;
• Increases application quality of concrete without alteration of water/cement ratio;
• Does not contain chlorine.

Preparation of the mixture. The concrete is loaded in transmixer at the 14±1 cm viscosity (according to the standard the viscosity should be lower in winter). The transmixer operator should also receive from the concrete factory a full can of FLOTON MOD N plasticizing admixture. The can has two marks (lines) indicating 1/3 and 2/3 of the volume. Depending of the number of vehicles waiting in the queue, five minutes before beginning of concrete pouring the transmixer operator should add to the barrel: for 7-9 m3 of concrete - full 10 kg can; for 4-6 m3 of the concrete – 2/3 of the can content; and for 2-3 m3 of concrete – 1/3 of the can content. The barrel should mix the product for three minutes with at highest speed. This period is enough to obtain a homogeneous mixture. At the end of this procedure the concrete viscosity will reach the S-4 index or 6-8 cm increase. In case the delivered concrete meets the required viscosity of the construction site which is S-3 or higher, then the concrete should be unloaded without adding the admixture.

Chemical admixture 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 amount of water provides the required application conditions. The concrete mechanical strength is increased proportionally to the reduction of water content in the mixture.

Compatibility to other admixtures. FLOTON MOD N may be used together with the following materials:

• All grades of cement;
• Quartz sand, volcanic cinders and slag, if required, when large amounts of adhesive substances are required;
• Admixtures of OKETON and FLOTON series;
• To increase resistance to freezing and melting temperatures, it may be used together with the AntiAir 250 air entraining admixtures;
• 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, likeMA Kur 100, MA Kur 200 and MA Kur 300;
• It is not recommended to use the FLOTON MOD N product together with other FLOTON series plasticizing admixtures.

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

It is recommended to add the FLOTON MOD N product in proportion of 0.4-0.7% of the cement amount. Depending on the concrete type and characteristics, the actual amount of admixtures should be defined based on preliminary laboratory tests.

FLOTON MOD N 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 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;
• in case admixture the concrete viscosity is higher than S-3 do not add the FLOTON MOD N product to the concrete;
• 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 equal to 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.
