FDN naphthalene series high efficient water reducing agent - TD-FDN

FDN naphthalene series high efficient water reducing agent

Main technical index

1, appearance: powder for tan powder, water for brown viscous liquid.

2, solid content: powder 94% or higher, the liquid 40% or higher.

3 flowability, net 230 mm or higher (dosage was 0.4%).

4, sodium sulfate content of 8% or less (high concentration); Sodium sulfate content of 20% or less (low).

5, chloride ion content in 0.5% or less.

6, each age than compressive strength, shrinkage ratio and other indexes satisfy GB8076-2008 "concrete admixture" regulation of indicators.

The performance characteristics

1 basic phase, the concrete strength and slump at the same time, 10 ~ 25% can reduce the dosage of cement, at the same time improve the durability of concrete and volume stability;

2, this product is water reducing rate can reach 15-25% of water phase at the same time, can improve the fluidity of fresh concrete, improve the working performance;

3, a significant early strength of concrete, enhancing effect, 3 d, 7 d, 28 d compressive strength increase of 20 ~ 60%;

4, increasing the compactness of concrete, reduce shrinkage and creep, to improve the durability of concrete;

5, have the good adaptability to various kinds of cement, have good compatibility with other concrete admixture ;

6, especially suitable for used in the following concrete works: flow, plasticizing concrete, concrete pipe concrete, concrete permeability, waterproof concrete, natural curing of prefabricated concrete, reinforced and prestressed concrete, high strength and high strength concrete.

Content range

Powder: 0.5 ~ 1.5%; Liquid: 1.5 ~ 2.5%. With the increase of dosage, water reducing rate can reach more than 20%.

Matters needing attention

1, the use of porous aggregate appropriate to add water, stir to add and subtract water;

2, when large slump, vibrating time not too long, should be paid attention to in order to prevent bleeding and layered;

3, before using this product, should do the concrete test experiment .

Packaging and storage

1, powder with woven bag, and lined with double layers, 25 kg net weight for each bag, can also according to customer's need to provide other specifications packaging or bulk, transport and storage should avoid damage and be affected with damp be affected with damp.

2, water use airtight bottled or canned.

3, powder shelf life is 2 years, water shelf life is 6 months.
