Naphthalene-based water-reducing agent (high concentration type) is a higher-performance concrete water-reducing agent after deep processing and purification based on the production of naphthalene-based water-reducing agent. It does not contain chlorine salt, the content of sodium sulfate is less than 5%, it is non-corrosive to steel bars, non-toxic and non-polluting. In addition to having all the advantages of naphthalene-based water-reducing agents, it can avoid alkali-aggregate reactions due to high aggregate activity or concrete engineering in a humid environment, and prolong the service life of the concrete. It is a low-alkali and high-concentration non-air-entraining water-reducing agent, which has a strong dispersing and plasticizing effect on cement particles; it can be used to prepare concrete with C60 and above. It is widely used in various concrete projects such as railways, highways, bridges, hydropower, ports, wharves, industrial and civil buildings, prefabricated components, and concrete with requirements for sodium sulfate content. It enables the performance of naphthalene-based water-reducing agents to be further extended and brought into play.
Product technical indicators:
1. This product is harmless to humans and animals, and has a wide range of adaptability to cement.
2. The dosage is 0.5~1.5% of the cementitious material, and the water reduction rate is 15~25%.
3. The appearance is yellow-brown powder or brown liquid, easily soluble in water, stable chemical properties, and will not deteriorate after long-term storage.
4. Under the condition of keeping the workability and strength of concrete unchanged, 15-20% of cement can be saved; under the condition of the same mix ratio, the initial slump of concrete can be increased by more than 10 cm.
5. The water-reducing effect is obvious, which can improve the workability of concrete and improve the fluidity of concrete under the condition of low water-cement ratio.
6. Reinforcement can increase the strength of concrete by 50-100% in 1d, 40-80% in 3d, 30-70% in 7d, and 30-60% in 28d.
7. This product is low in alkali, low in sodium sulfate, effectively avoiding concrete alkali-aggregate reaction, no precipitation or crystallization at low temperature.
Key points of application technology
1. Strictly follow the requirements in the "Technical Specification for the Application of Concrete Admixtures".
2. When using or replacing cement for the first time, adaptability test and determine the * content should be done first.
3. The post-tragedy method will have better economic benefits, but the mixing time should be extended appropriately.
4. It is advisable to use mechanical stirring to do a good job of maintenance.
5. The dosage is calculated according to the percentage of the gelling material. If a liquid product is used, the water content will be reduced in the proportion after the solidification.
