| HY-1000 Naphthalene series high-efficiency water reducing agent |
| Introduction |
The main component of HY-1000 naphthalene series high-efficiency water reducing agent is ?-naphthyl sulfonate formaldehyde condensate with the characteristics of high-efficiency water-reducing rate, low alkali content and non-corrosive to reinforced steel. It strictly implements the standards of GB8076-1997 concrete additive, GB/T8077-2000 concrete additive average test method and GB18588-2001ammonia releasing limit concrete additive. | |
Features |
1, It has powder and liquid products. The powder product is chocolate brown and the liquid is brownish-black color. It is toxicless, odorless, inflammable and non-corrosive to reinforced steel.
2, Increasing strength. Adding 0.3%~1.5% product in cement, it can reduce above 9%~29% water during the same of cement dosage and slump constant.
With this product, the compression-proof of one day can be increased by 70%~100%, three-day compression-proof can be increased by 50%~80% and twenty-eight compression-proof can be increased by 25%~50%. The physical mechanics of cement is also increased a great deal and increase the compression-proof, tensile, demolition proof, elastic module and long-term strength.
3, It can improve the workability and slump constant of cement.
4, It can help to save cement. Under the same slump constant and strength, It can save cement by at least 12%. | |
| Application |
1, It is fit for sorts of prefabrication and casting cement, reinforced steel cement and pre-stress of industrial and civilian use building, irrigation works, traffic, port, municipal works, etc.
2, It is fit for deploy early strength cement, high-strength cement, high leakage cement, self-compacting concrete and self-flowing grouting material.
3, It can be used in the natural conservation and steam curing project and product. It has vivid slushing and strengthening, accelerates model and ground revolution and shorten completion period.
4, It is well fir for silicate cement, common silicate cement, slag silicate cement, etc. | |
| Admixture |
According to different strength and application range of cement, the general admixture range is 0.3~0.8%. If making high strength cement, the admixture range can be controlled in 0.8~1.8% with the most proper admixture is 0.75%. | |
| Using method |
1, It is used in the needed solution.
2, Powder product can be used directly or indirectly.
3, It can be matched with other additive, but it needs to be tested. | |

| Notice |
1, The addition of HY-1000 Naphthalene series high-efficiency water reducing agent is 0.5~0.75% of cement.
2, The powder products can be added directly or made into solution.
3, When the temperature is low, HY-1000 Naphthalene series high-efficiency water reducing agent can match with early strength admixture to increase early strength.
4, After test, it can be used in silicate cement, common silicate cement, flyash silicate cement, etc.
5, Avoid moistening during transportation and storage.
6, During stirring, the dosage should be strictly controlled. | |
| Safety guide |
1, Nontoxic and inflammable.
2, If it touches eyes, wash it right away by clear water or go to the hospital. | |
| Packing, storage and transportation |
1, The powder products are packed in woven bag lined with plastic film. Net weight 25kg¡À0.13 kg or 50 kg¡À0.25 kg; The liquid products are packed in closed plastic drum or transported by tank car.
2, Te powder products should avoid edgy object. | |
| Expiration date |
