Product description
BEMATON 3055 is a polycarboxylate ether based, high water reduction, latest generation super plasticizing (increasing concrete plastic properties) concrete admixture, which prevents decrease of concrete viscosity, provides high resistance and strength, and is improved for concrete industry.
The product conforms to the requirements of the following standards: AZS 221-2006 (TS EN 934-2), Tables 3.1 and 3.2: “High water reduction, latest generation super plasticizing (increasing concrete plastic properties) concrete admixture”, and ASTM C 494 Type FF: “high water reduction, latest generation super plasticizing concrete admixture”.
Fields of Application
This concrete admixture can be applied in the following areas:
- Production of self-flow and self-compacting concrete;
- Pouring of concrete using pumps in long and high structures (constructions), does not affect concrete viscosity, provides excellent flow;
- Production of Rheodynamic concrete of free flow in reinforcement cages;
Advantages
- Increases early and ultimate strength of the laid concrete, provides ultimate tension, high adhesion to steel, as well as impermeability and hardness compared to conventional super plasticizers (Naphthalene sulfonate based materials – NSM and Melamine sulfonate based materials – MSM);
- Improves resistance of concrete to liming and chlorine ions, to aggressive chemical substances, improves such mechanical characteristics of cooled concrete, as compression and tension;
- Production of Rheoplastic concrete of low risk of disintegration (separation) and spalling, improved operating parameters at low water/cement ratios compared to concrete without admixtures;
- Provides excellent filling factor of concrete inside formwork; Unlike conventional super plasticizers (NSM and/or MSM) it maintains the concrete viscosity and does not slow down concrete curing at low water/cement ratios, eliminates necessity of repeatedly monitor and adjust concrete viscosity at the construction sites;
- concrete with the latest generation super-plasticizing admixtures freely flows in the formwork without vibrator tools operation;
- Does not contain chlorine.
Application procedures
Preparation of the mixture. Mix the mineral adhesives (cement, quartz sand, volcanic cinders, slag) with concrete filler till the mixture is entirely homogeneous. Add 50-70% of the required water amount and then add the BEMATON 3055 product together with the remained amount of water to the mixture. To provide homogeneous composition of BEMATON 3055 mixture vigorously mix it during 60 seconds or during time period predefined in the process of laboratory tests.
Chemical mechanism of the latest generation plasticizers reaction. During the very initial stage of concrete mixing the surfaces of cement particles are covered with conventional melamine and naphthalenesulfonate based super plasticizing polymers. Sulfated groups of polymer chains increase negative loading of cement particles, and these particles are repelled by electrostatic force. This electrostatic mechanism results in disintegration of the cement paste, and enhances usage and preparation of the concrete with smaller amount of water added. Simultaneously the hydration process starts. The fast-growing hydration crystals change the surface mechanism of the particle, therefore preventing free disintegration of the particle surfaces.
The difference between the BEMATON 3055 product and conventional super plasticizers (NSM or MSM) is in this new unique mechanism of influence which improves performance of the cement fraction.
The BEMATON 3055 consists of long-chain carboxylate ether polymers. At the beginning of mixing process the electrostatic repelling mechanism starts similar to that of conventional super plasticizers. This process results in producing the plasticized concrete (with better plastic properties) due to significant reduction of the water demand. However the polymer bound chains stabilize disintegration and repellence properties of cement particles and create a sterile barrier. Due to this feature the smaller amount of water provides the higher plasticity (flow properties).
High alkalinity of cement paste provides unwinding and expansion of additional polymer chains in the structure of the BEMATON 3055 product preventing premature thickening of the concrete. This mechanism, compared to conventional super plasticizers of hardening inhibitor properties, does not inhibit the concrete hardening, but provides conditions for its long-term useful life and significant reduction of intensive water demand.
Compatibility to other admixtures. BEMATON 3055 may be used together with the following materials:
- All grades of cements;
- Self-flow mineral adhesives (quartz sand, volcanic cinders and slag) if required in the cement production process;
- To increase resistance to freezing and melting, 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 hot climate conditions and in the areas of high air velocity the product can be used together with corresponding moisture-retaining products, like MA Kur 100, MA Kur 200 and MA Kur 300;
- The product cannot be used together with FLOTONseries (based on NSM) admixtures.

Consumption
It is recommended to add the product in proportion of 1.0-2.0% of the cement amount. Depending on the concrete type and characteristics, amount of the admixture should be defined during preliminary laboratory tests.
Shelf Life and Storage Method
BEMATON 3055 should 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 of water, then should be mixed using mechanical methods till it is entirely homogeneous. When mixing compressed air should not be used.
Under required storage conditions, the product may be stored during 12 months from the manufacturing date. The product in open containers may be used during entire storage period provided the cap is kept closed.
Warnings
- 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;
- do not use the product together with FLOTON series admixtures (based on NSM);
- mix the fine or coarse concrete fillers with mineral adhesives defined upon results of the laboratory tests (cement, quartz sand, volcanic cinders, slag) till the mixture gets 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. Even if you add water afterwards to such improper mixture, the required type and characteristics of the concrete will not be obtained. In case water is added to the mixture in larger amounts than required this will unbalance the required design factors of the concrete and the 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;
- in case the BEMATON 3055 concrete admixture is used at ambient temperatures below +150C, it is necessary to adjust the amount of cement with regard to other required conditions (temperature and time period);
- in case the BEMATON 3055 product is mixed with admixtures of other categories, the resulting quality will be poorer. On this reason this admixture should be handled with clean tools and devices only.
- parameters indicated above have been received on the basis of laboratory tests conducted in the ambient conditions of +230C±20C temperature and 50% +5% humidity. Depending on the actual ambient conditions these parameters are subject to change.
