Detailed Introduction

YL-SNF-C-萘系高效减水剂

YL - SNF - C naphthalene series high efficient water reducing agent (low concentration type)
 
Products overview:
         YJ - SNF - C high efficiency water reducing agent is the chemical synthesis of air-entraining type high efficiency water reducing agent.The chemical name for beta naphthalene sulfonate formaldehyde condensation product.It for cement particles has a strong effect.Of mixed flow state of concrete, early strength, high strength requirement of cast-in-situ concrete and pre-cast component, has the very good use effect, can improve and improve various properties of concrete, has good applicability to common cement, can be used for roads, Bridges, tunnels, DAMS, ports, the electric power engineering and water conservancy facilities engineering, industrial and civil construction, prefabricated pipe and natural maintenance, etc.

The main technical performance:
           1、Dosage for gelled material dosage of 0.5 1.5%, water reducing rate can be up to 12-28%.Early strength, enhanced obviously, the concrete strength increase 60-130% for three days, seven days strength increase 40-60%, 28 days strength increased 20-40%, long-term strength is increased.
           2、Keep the concrete strength and slump at the same time than without saving water reducing agent of concrete admixture cement 15-20%.
           3、Added to this product can greatly improve the workability of concrete, concrete mechanics performance, make the concrete compressive strength, tensile, bending strength, elastic modulus and long-term strength has increased accordingly.
           4、This product has good adaptability to various cement.Such as Portland cement, ordinary Portland cement, slag cement, ash, cement, etc.
           5、Suitable for high strength concrete, flow pattern, early strength of concrete, precast concrete pipe concrete and prestressed concrete, etc.
           6、The products are powder and liquid, liquid to solid content is 40 + 2%, the proportion of 1.22 or higher, dosage of 1.5-3.0%, other performance index is the same.
           7、Use of this product can be used as the composite masterbatch and other components, formulate the different features of admixture (such as early strength jianshuiji, retarding superplasticizer, pumping antifreeze and pumping water reducing agent, etc.), fully meet the engineering category, construction technology, construction technology, and the temperature condition.

Application technology main points:
             1、The powder is given as a percentage of gelled material, liquid products according to the solid content reduced usage, cut out from the ratio of water content.

             2、After mixing method, adaptive extended mixing time and mean well.

             3、Liquid should be used in more than 15 ℃ temperature and storage, avoid sodium sulfate crystallization.

Package and storage:
             1、Powder products with plastic external preparation of double packing, each bag is 25 kg;Liquid using plastic or iron drum packaging, 50 kg, 220 kg a barrel, according to user needs to adjust.
             2、Powder should be stored in a dry and ventilated place, agglomeration can be used after crushing, does not affect the use effect.                                
             3、Expiration date: 1 year, extended after test qualified can still use.
