Performance quality index of synthetic Water Reducing Agent:
This product can react with unsaturated acids such as Acrylic Acid and maleic anhydride. The produced polycarboxylic acid Water Reducer has the characteristics of high cost performance, high water reduction rate, good plasticity retention and excellent durability.
·High cost performance. In the case of reaching the same water reduction rate, it has a higher cost performance.
·Low dosage and high water reduction rate. The water-reducing agent mother liquor with 20% solid content and 1.0% (the amount of gelling material) can achieve a water-reducing rate of 30-35%.
·Good plasticity retention. The slump loss of concrete is small after 1 h.
·Excellent durability. It can greatly reduce water consumption and improve the durability of concrete.
·Green. The production process of water reducing agent does not use formaldehyde, which is harmful to the environment, and the content of chloride ion and sulfate radical is low.
Application areas:
The polycarboxylate water-reducing agent produced by this product can be used to prepare retarded concrete, precast concrete, cast-in-place concrete, high-performance concrete, large flow concrete, self-compacting concrete and mass concrete, and can be widely used in high-speed railways, Large-scale bridges, water conservancy, hydropower, nuclear power, subways, highways, harbors, and various industrial and civil construction projects.
Packing specification:
The sheet is packed in a 25 kg woven bag.
Storage and transportation:
This product is non-toxic and non-flammable. It can be handled in accordance with general chemical transportation regulations. It should be stored in a dry and ventilated place, and avoid sunlight and rain.
