Polycarboxylic acid high performance water reducing agent 

(early strength type)

Product introduction

FEM Polycarboxylic high-performance water-reducing agent (early strength type) makes the molecular structure tend to introduce strong polar genes into the main chain or side chain of the molecule. It has a comb structure and can adjust the molecular weight of the polymer to meet different requirements. After defoaming, It is compounded by adding early strength and air-entraining components, and complies with the " GB8076-2008》、《TB/T3275-2011》 National standard.

Features

High water reduction rate;

The slump loss over time is small;

Early morning intensity is high;

It has good adaptability to mineral admixtures such as fly ash, mineral powder, and silica fume used in the preparation of high-performance concrete.

Technical performance and recommended dosage

Technical performance: This product is a polycarboxylate water-reducing agent PH Value is 5 ~7；

The products are non-toxic, harmless and safe for health and the environment.

Recommended dosage: 1.8% of cementitious material dosage ~2.2%。【Note: When preparing ultra-high-strength concrete, the dosage can be appropriately increased]

How to use and precautions

Before use, the optimal dosage should be determined based on project construction requirements, material characteristics, and trial preparation.

When compounding with other admixtures, its compatibility should be checked first, and it cannot be used in combination with naphthalene series water-reducing agents. When used in combination with other types of admixtures, tests should be conducted to confirm.

After the concrete is poured, the concrete should be maintained according to the provisions of the construction regulations. Winter construction can follow the "Winter Construction Rules".

Changes in sand, stone content and admixture quality have a greater impact on the water-reducing effect of the product. Users should choose orthopedics and admixture materials that meet the standards.

Scope of application

It is suitable for configuring various grades of pumped concrete and long-distance transportation of commercial concrete.

Suitable for high-strength concrete, high fluidity, self-compacting concrete, large-volume concrete, and high-performance concrete structures.

It is suitable for various civil construction projects and high-rise reinforced concrete frame structures, especially for highways, railways, bridge projects, tunnel projects, hydraulic dams, nuclear power projects, ports, docks, underground facilities and other large-scale projects that require high concrete durability. Concrete structure, also suitable for the production of large-scale prestressed concrete beams and slabs, steam curing concrete, etc.

Can be used as parent component for compounding.
