AM-200 (economic) is developed by our company is an environment-friendly polycarboxylate ethers high performance water reducer, it has a high water reducing rate, low cost, low alkali，suitable for a variety of ready-mixed and in-situ concrete of industrial and civil constructions which require lower level of coagulation slump, especially in the commercial concrete application .Good economy.
Features and Benefits
1 ,It has high water reducing ratio (up to 35%), good dispersion, and provide a guarantee to improve concrete performance, increase the strength of concrete, save cement.
2, It has generally mobility sustained, by composite a certain percentage with other polycarboxylate high range water reducer, it can increase sustained performance, and saving costs.
3, Mixed concrete can significantly improve the workability of the concrete mixture; It can reduce the viscosity of high performance concrete effectively, improve the performance of construction, not be easy to segregation and bleeding, and easy pumping.
4 ,This product can improve the early strength and late strength of hardened concrete, impermeability and frost resistance, and improve the contractile properties ,creep performance and durability. It reduces the rate of carbonation of concrete, alkali- aggregate reaction.
5 ,Due to low content of alkali and chlorine ion, it improves the durability of concrete. It has a good adaptability for a variety of Portland cement, ordinary Portland cement, slag Portland cement and mineral admixtures.
6, It has a good economy, particularly suitable for the commercial concrete.
The formaldehyde content (according to solid content exchanging) (％)
The fluidity of cement paste(mm)
1, Adapt to a variety of industrial and civil construction, rail, water, marine,port, transportation, bridges, municipal, and electric power engineering andin-situ concrete, reinforced concrete, prestressed concrete and commercial concrete.
2, Adapt to different strength grades of concrete, especially suitable for the key projects of all kinds of high-performance concrete.
3, This product is particularly recommended for high strength and high durability concrete, the superfluid self-compacting concrete, pumping concrete, precast components, steel fiber and special concrete.
4, Composition with other polycarboxylate high performance water reducer at certain percentage, it is used in the place with higher requirement, such as commercial concrete, mean while saving costs.
The using method
1, This product recommended content is 0.25% -0.85% of the total weight of cementitious material, actually content should be experimentally determined.
2, Due to the adaptive differences between different types of the cement and admixtures, The adaptive test of cement and admixture should be done before using or changing the cement type.
3, In order to achieve better water-reducing effect, and ensure the quality of concrete, the mixing time is recommended at least 120 second before the concrete mixing test.
4, This product is sold as raw material, it shows good compatibility with a variety of retarders, defoamers, and air-entraining agent. Processing compound is not recommended to be used directly on the concrete and other materials. It is strongly recommended through trial and complex technology to determine the using method and conditions prior to use. It can be used as a masterbatch that mixed with different characteristics agent to produce retarded setting agent, early strength agent cryoprotective agent and pumping agent, it can fully meet the requirements of the different categories of engineering, construction technology, construction technique and temperature conditions.
Packaging, transport and storage
(1) It is packed in 1000Liter per IBC Tank, Other special package can also be available according to prior consultation.
(2) Special measures should be taken to ensure entire package. Keep waterproof during transportation.
(3) Dry and well ventilated warehouse is needed for storage. Quality guarantee of AM-200 is six months under normal conditions. If storage has surpassed the time, test must be done to confirm the validity.
Health and safety
(1) Once splashed into eyes and skin, wash immediately with plenty of water and seek medical treatment.
(2) Inedible. When eating by mistake, drink sufficient water to urge to vomiting, and then go to hospital.
(3) No littering. Caution should be taken to protect environment.
