Performance and quality index of synthetic water reducing agent:
This product can react with unsaturated acid such as acrylic acid and cis-butylillic anhydride. The polycarboxylic acid-based water reducing agent produced has high cost performance, high water reduction rate, good plasticity and durability. Excellent and so on.
· High cost performance. In the case of achieving the same water reduction rate, it has a high cost performance.
· Low dosage and high water reduction rate. The mother liquor containing 20% solids of water reducing agent, the dosage of 1.0% (the amount of cementing material), the water reducing rate can reach 30-35%.
· Good plasticity. The slump loss was less after 1 h of concrete.
· Excellent durability. It can greatly reduce water consumption and improve the durability of concrete.
·Green. The environmentally harmful formaldehyde is not used in the production of water reducing agent, and the chloride ion and sulfate content are low.
Application: Polycarboxylate water reducer produced by this product can be used to prepare retarding concrete, precast concrete, cast-in-place concrete, high performance concrete, large fluid concrete, self-compacting concrete and mass concrete. It can be widely used. High-speed railways, large bridges, water conservancy, hydropower, nuclear power, subways, highways, harbor terminals and various construction projects.
Packing specification: The sheet is packed in 20 kg woven bag.
Storage and transportation: This product is non-toxic and non-combustible. It can be handled according to the general chemical transportation regulations. Store in a dry and ventilated place to avoid sunlight and rain.
