The main performance

1 concrete mixed with 0.5-1.5% of the goods after water reduction up to 14 - 25%, and enhance the effect is significant, make concrete one day, three days compressive strength were increased by 60-80%, and 40-60 %, mixed and non-mixed admixture admixture concrete compressive strength of 40-60%, 20-40% of 28-day strength increased specific dosage should be determined by testing the most recommended routine doping of 0.75 - 1.0%.

(2) Concrete incorporation of the goods, while maintaining the slump and strength similar to the case, can save 10-20% of cement.

3 concrete mixed with the goods, can greatly improve the workability of concrete, increasing the density and impermeability of concrete, improve workability and durability of concrete

4 can be suitable for Portland cement, ordinary portland cement, slag cement, fly ash cement, composite cement.

5 can be formulated as a masterbatch special properties of admixtures.

6 can be formulated C10 - C60 multiple uses various strength grade concrete, suitable for high-strength concrete, early strength concrete, high fluidity concrete, steam curing concrete. Prestressed reinforced concrete Nirvana, Nirvana hydraulic concrete and so on.

7 .. reinforced concrete lining will not rust effect

Use and injection exhausted matters

1 wood products can be used with other additives such as early strength agent, Air-entraining agent, retarding Jing, etc. with the use test must be carried out prior to use with.

(2) In the initial use of the product or cement variety is changed with a trial ahead of the best, choose the best dosage.

3 concrete mix in fly ash, slag and other active when admixture, water reducing agent dosage should be calculated in the total cementitious material.

4 blending the product of concrete mixing time should be extended by 30 seconds or more.

5 This product should not be below 10 ° C melting into aqua use (easy to generate less li sulfate crystals), it shall be heated or reduce the concentration of aqua.

Instructions for use

1. PowderPacking, plastic bag lined woven bagPacking.

2. Powder should be kept dry and dry place Note exhausted moisture, but the moisture does not affect the results.

3 drying Shape Shelf life under two years, after extended through concrete test with grid before continued use.

Description: According to the actual requirements of the user and engineering. Sometimes needs the particular formulation FDN-HP high efficient water reducing agent, according to project specific requirements, the actual use of raw materials as well as the specific conditions of the site and determine the product dosage formulations to bring optimal concrete quality and the best value for money.

FDN-HP (liquid) High concentrated high efficient water reducing agent

Introduction

Technical performance of this product are in compliance with international GB8076-2D08 concrete admixtures required standards. Based β naphthalene sulfonic acid condensate sodium salt as the main ingredient high efficient water reducing agent is made by the purification process, with less water is high, plastic of the effect is good, good adaptability etc. It is widely used in a variety of roads, bridges, tunnels, ports, industrial and civil construction.

Index of uniformity

Item	Appearance	Fluidity of cement paste	Density (G / CM3)	Sodium sulfate	Solid	PH
Index	black brown	≥ 230MM	1.20 ± 0.003	≤ 2%	(40 ± 0.5)%	7 - 9

Dosage range: (as calculated total cementitious material!

According to breaking strength and site construction requirements, the dosage may be 0.8-2.5% range determined by experiment.

Conventional dosage of 1.2 - 1.8%.

Key Features:

1 concrete mixed with the product 1.2 - 1.8% water reduction of up to 14-25%, the use of dosage limit up to 30% water reduction, early strength, can significantly enhance the effect of compressive strength of a concrete day increased 60-80%, 40-60% increase 3 days, 28 days increased 25-44%.

(2) Concrete incorporation of the goods, while maintaining the slump and strength similar to the case, can save 10-20% of cement.

3 concrete in the cover into the goods, can greatly improve the workability of concrete, increasing the density of concrete and impermeability. Improve concrete workability and durability.

4 can be suitable for Portland cement, ordinary portland cement, slag cement, fly ash cement, composite cement.

5 can be formulated as a masterbatch special properties of admixtures. Adapt to a wider range of temperature, -5 ° C above does not produce crystallization.

6 C10-C80 can be prepared a variety of multi-purpose concrete strength grade, suitable for high-strength concrete, early strength concrete, high fluidity concrete, self-compacting concrete, steam curing concrete, prestressed concrete, hydraulic concrete.

7 reinforced concrete lining will not rust effect.

Using methods and precautions

1 This product can be used with other additives such as early strength agent, Air-entraining agent, retarder, etc. used in conjunction with test must be carried out before use.

(2) In the initial use of the product or cement variety is changed ahead of the best trial match. Choose the best dosage.

3 concrete mix in fly ash, slag and other active when admixture, water reducing agent dosage should be calculated in the total cementitious material.

4 blending the product of concrete mixing time should be extended by 30 seconds or more.

Packing, transportation, storage

1. Tank car, or 200G metal pail or 50G plastic drum.

2. Storage should be in a sealed container, anti-intrusion on Moisture evaporation and rainfall, resulting in Solid changes affect the results.

3 sealed container sealed, Shelf life one year after the super Shelf life should be confirmed only after passing through the test used.
