< < Scope of application< < = As a raw material for admixtures, it is suitable for various cast-in-place and Precast concrete, reinforced concrete, prestressed concrete, especially suitable for commercial concrete, freeze-thaw resistant concrete, large volume concrete, pumped concrete, large formwork concrete, slip form concrete, waterproof concrete. <=This product can be used in combination with other basic admixtures and has good adaptability. < < Precautions for use< < = Parameters must be strictly controlled during the construction process. Remember to overdo it or exceed the parameters, which may cause the setting time to be significantly prolonged or even not hardened. According to different use requirements, you can refer to the following parameter ranges and combine them with local actual conditions. The proportioning test determines the actual parameters. < < When used as a raw material for water-reducing agent, the parameter selection range is ..% < When used as a retardant or air-entraining water-reducing agent raw material, the parameter selection range is ..% < When used as a composite water-reducing agent raw material, the parameter selection range is used. .% < < = The retarding effect of this product increases significantly as the temperature drops. The lower the temperature, the slower the strength growth. < = This product is easily soluble in water (hot water is better) and can be formulated into an aqueous solution with a concentration of %. When dissolving, first put water into the container, and add sodium lignosulfonate while stirring. Remember to pour a large amount of water quickly to avoid clumping or prolonging the dissolution time. After preparing the solution, it should be used up within a day to prevent mildew. Change. < = This product may cause false setting when using cement with anhydrite or fluorogypsum as a modifier. The suitability test of cement varieties is required before use. Before being used as a raw material for concrete water-reducing agent, a mix proportion test must be carried out, and it can only be used in projects if it meets the technical requirements. < = For concrete with specified air entrainment volume, when the air entrainment volume is too large, appropriate vibration time must be selected, or other defoaming measures must be adopted to ensure that the air content reaches the technical requirements. < = When the concrete added with this product needs to be steam-cured, the resting time should be appropriately extended or other admixtures should be combined, and technical measures such as reducing the parameters of sodium lignosulfonate should be taken to prevent the occurrence of strength reduction or loosening.
