萘系高濃高效減水劑FDN-A高性能無氯減水劑（粉劑）

Naphthalene Series High Concentration Superplasticizer

FDN-A High Performance Chlorine-Free Water Reducing Agent (Powder)

一、適應范圍
1、適用于現澆，預制的鋼筋混泥土，以及外摻粉煤灰混泥土。

2、適應配制早強，高強，高抗滲，自密實，泵送混泥土及流灌漿材料。

3、可以廣泛用于自然養護及蒸汽養護的混泥土工程及制品。

4、對于硅酸鹽水泥，普通硅酸鹽水泥，礦渣硅酸鹽水泥，粉煤灰硅酸鹽和火山灰硅酸鹽水泥均有較好的適應性。

5、可用于配制各種系列的混泥土外加劑。

二、主要性能
1．SH-II型減水劑符合國家標準GB8076-1997《混泥土外加劑》。

2、SH-II型粉劑產品屬萘系高效減水劑。外觀呈棕褐色無毒無嗅不然，對鋼筋無銹蝕作用。

3、在混泥土中加入推薦摻量的SH-II粉劑，在水泥用量和坍落度相同的情況下，可減少拌合用水量的15-25%左右，其一天強度可提高50-80%，三天強度可提高40-70%，二十八強度可提高30-50%，并且可大大提高和改善混泥土各種物理力學性能。用普通硅酸鹽水泥可配制40-80mpa的高強混泥土。

4、在相同的水泥用量及水灰比不變的情況下，可明顯增大混泥土的坍落度，改善混泥土的和易性，坍落度可增1.0-1.5倍。

5、在坍落度和強度基本相同的情況下，可節約水泥10-15%。

6、可大大提高和改善混泥土的各種力學性能及抗滲等耐久性能。

三、性能指標

三、推薦摻量

本產品推薦摻量為干混砂漿材料用量的0.4-0.6%,一般其它減水劑常摻量為0.8%左右

I. Scope of adaptation

1. Suitable for cast-in-place, prefabricated reinforced concrete, and mixed with fly ash concrete.

2. Suitable for the preparation of early strength, high strength, high impermeability, self-compacting, pumping concrete and flow grouting materials.

3. Mixed soil engineering and products which can be widely used in natural and steam curing.

4. Portlａnd cement, ordinary Portlａnd cement, slag Portlａnd cement, fly ash Portlａnd cement and volcanic ash Portlａnd cement all have good adaptability.

5. It can be used to prepare various series of admixtures for concrete.

II. Main Performance

1. SH-II water reducer meets the national standard GB8076-1997 "Mixed soil admixture".

2. SH-II powder belongs to naphthalene series superplasticizer. The appearance is brown, non-toxic and odorless, otherwise, it has no corrosion effect on steel bars.

3. When the recommended amount of SH-II powder is added to the concrete, the amount of water used for mixing can be reduced by 15-25% with the same amount of cement and slump. Its strength can be increased by 50-80% in one day, 40-70% in three days, 30-50% in twenty-eight days, and all kinds of physical and mechanical properties of the concrete can be greatly improved and improved. 40-80 MPa High strength concrete can be prepared with ordinary Portlａnd cement.

4. With the same cement dosage and water cement ratio unchanged, the slump of concrete can be significantly increased, the workability of concrete can be improved, and the slump can be increased by 1.0-1.5 times.

5. When the slump and strength are basically the same, the cement can be saved by 10-15%.

6. It can greatly improve and improve the mechanical properties and impermeability of concrete.
