DH-702 Polycarboxylic acid slump preserving agent

　　DH-702 polycarboxylic acid slump preservative is a new generation of slow-release high performance slump preservative developed by our company, which has excellent slump retention function and good adaptability, and also better improves the plasticity index of fresh concrete so as to improve the construction performance and the strength and durability of concrete. It is widely used in normal concrete, pumped concrete, super-fluid self-compacting and high-strength durable concrete.

Note: Product homogeneity test method refer to GB\T8077-2012

       1. High water reduction rate: Tested according to the requirements of GB\T8076-2008 "Concrete Admixture" standard, the water reduction rate of the product can be more than 35%, which improves the working performance of concrete, increases the strength of concrete and can save a certain amount of cement, so the economic benefits of using the product are more obvious.

　　2. better slump retention: it can extend the slump and transportation time of concrete, which ensures the pumping construction performance of concrete.

　　3. good adaptability: the product has good compoundability and can be used with mainstream slump-proofing agent, retarder, defoamer and air-entraining agent in the market, which can formulate high-performance water reducing agent with different performance. It has good dispersibility and plasticity preservation for various types of cement, fly ash, mineral powder and sand and gravel materials.

　　4. High strength growth rate: higher strength growth rate, improve the shrinkage of concrete and reduce the carbonation rate of concrete.

　　5. Safety: The product is non-toxic, non-radioactive, non-flammable and non-explosive, does not contain substances harmful to steel and aggregate corrosion, does not contain formaldehyde and other aromatic residues harmful to human body, and can meet the current indoor and outdoor environmental requirements.

　　6. Good product stability: no stratification and no precipitation in long-term storage.

       1. Suitable for ready-mixed and ready-mixed concrete of various industrial and civil buildings.

　　2. Suitable for various national infrastructure projects with high requirements for concrete, such as various water conservancy, marine engineering, harbor, electric power, etc.

　　3. Suitable for special concrete such as high-strength, high durability, self-compacting and various prefabricated components.

       1. The product can be compounded with retarder, collapse inhibitor, air-entraining agent, defoamer, thickener and other materials and added into concrete to meet the various indicators of concrete.

　　2. The amount of admixture after compounding is about 2% of the cementitious material, and the specific amount needs to be determined according to the test.

       1. The product liquid is packed in 200kg, 1000kg plastic drums, or according to customers' requirements.

　　2. Avoid direct sunlight, can be stored at 0-40℃.

　　3. The shelf life is 6 months, beyond the shelf life, it can be used only after passing the test.

       1. The product is non-toxic, non-corrosive, non-flammable and non-explosive green products, but not edible.

　　2. In case of eye contact, flush with water as soon as possible. In case of allergy to part of the body, seek medical attention.
