Natrium-Naphthalin-Formaldehyd Hoch effektive Wat

XF-V Sodium Naphthalene Formaldehyde High-effective Water-reducing Agent Operative Norm The performance follows the GB8076<concrete admixture> The construction follow GB<concrete admixture application standard Characteristics Appearance Light brown power PH value 7 9 Solid content ≥90% Fluidity of cement paste(mm) ≥210 Performance 1 Quantity: the quantity of XF-V super plasticizer agent is 1.0-2.0%. 2 Water-reducing rate: under the same ratio and same slump situation , water-reducing rate is 12-25%. 3 Increase 100mm ,improve the fluidity. 4 Condense time: same with standard concrete. 5 The strength of resisting pressure :3,7d≥130% 28d≥110% , save 5-10% cement under the same strength. Scope of Using 1 It is better to improve the workability of concrete, increase anti-permeability of concrete, anti-freezing ,if use the concrete among C30-C60. 2 Apply pump concrete in the construction site. 3 Apply the making of steel concrete, precast concrete, steam concrete, large precast parts and hollow board. 4 Apply concrete constructions of road, bridge, runnel and so on. Use Method 1 Mix together: mix with cement and then agitate with Aggregate and water. 2. Mix later : agitate only with water in 1-2min,then mix the product and agitate. 3 Mix in several times: mix into the concrete in two or several times . Package and Storage 1. For power, the standard of package is 25kg/bag or 40kg/bag. 2. Cautions should be taken to prevent from being torn by sharp-ended objects while packages are being transferred or delivered. It should be stored in a dedicated warehouse that is well-ventilated and dry. 3. The shelf life is one year. It remains effective in one year. After the expiration, date, it can be used again if testing results fall within the established range. Attentions 1. It is better to take machinery to agitate ,if the worker does it , firstly diluted with water then mix in the concrete, also prolong the agitating time and the water that use for diluted must be reduced from all the water quantity. 2. The vibrated method is the same with the ordinary concrete, if the slump is big, take care the time of vibrating in order not to be stratified before the grouting, in order to reduce slump. 3. The method on the transport, grout is the same with ordinary concrete. Shorten the time from loading to grouting. 4. Seal the bag if there are surplus materials in the bags, to prevent being wet. 5. Best to test the adaptability of the cement and the product; if you would change the cement, please test again according the specific requirement and the product description 6. Control the quantity of various materials and water, if use porous aggregate, take the method of mixing later. XF-V
