Classification:
Concrete Plasticizers
Keyword： Polycarboxylate high-performance water reducer
Detail
FEM polycarboxylate high-performance water reducer introduces strong polarity genes into the main or side chains of the molecule, with a comb like structure that regulates the polymer molecular weight to meet different requirements. The product performance indicators significantly exceed the performance indicators specified in GB8076-2008, JG/T223-2007, and TB/T3275-2011.
Product Features
High water reduction rate;
Low slump loss over time;
High strength, widely applicable to various engineering concrete needs;
The mineral admixtures such as fly ash, mineral powder, and silica powder used in the preparation of high-performance concrete have good adaptability;
The product can be compounded with air entraining agents, retarders, etc. to improve the construction performance of concrete.
Technical performance
This product is a polycarboxylate water reducer with a pH value of 5-7;
The product is non-toxic, harmless, and safe for both health and the environment.
The recommended dosage of cementitious material is 1.8% to 2.2%. [Note: The dosage can be appropriately increased when preparing ultra-high strength concrete]
Usage and precautions
Before use, the optimal dosage should be determined through trial mixing based on the construction requirements and material characteristics of the project.
When compounding with other additives, their compatibility should be checked first, and they cannot be used in combination with naphthalene based water reducers.
When used in combination with other types of additives, it should be confirmed through testing.
After pouring concrete, it should be cured according to the construction regulations. Winter construction can follow the "Winter Construction Specification". The changes in sand and stone content, as well as the quality of admixtures, have a significant impact on the water reduction effect of the product. Users should choose aggregates and admixtures that meet the standards.
Scope of Application
Suitable for configuring various grades of pumped concrete and long-distance transportation of commercial concrete.
Suitable for high-strength concrete, high flow state, self compacting concrete, large volume concrete, and high-performance concrete structures.
Suitable for various civil engineering projects, high-rise reinforced concrete frame structures, especially for large concrete structures with high durability requirements such as highways, railways, bridge engineering, tunnel engineering, hydraulic dams, nuclear power engineering, ports, docks, underground facilities, etc. It is also suitable for the production of large prestressed concrete beams and slabs, steam cured concrete, etc.
Can be compounded as a parent component.
