Натрий нафталинформальдегидного

This product is compound with early strength medicinal preparation, the antifreeze, the elasticize, the intensifier. It has uses in early strength, anti-frozen, enhancement. The quantity of mixture is small slight, using this product can shorten construction time, enhance the template and location’s turnover rate, save cement, prevent freeze injury. It conforms to JC473-2001 quality specification.

The early enhancement effect is remarkable: the concrete compressive strength 3 days same ratios enhance 60% 100%, 7 days to enhance 30% 50%, 28 days to enhance about 20%; 2. Rate of water Reduce: the mixture quantity: 2% 6%, Rate of water reduce to reach 12% 25%; 3. The product has a better compatibility to the Portland blast-furnace cement and the ordinary Portland cement; 4. To steel bar non- corrosive action; 5. The frostproof effect is good, may in -15Degrees Celsiusabove temperature normal construction. Matters of attention 1. The mixture quantity: this product recommendation mixes the quantity is: (According to weight of cement ) When 0 5Degrees Celsius, 2%-3% When -5 -10Degrees Celsius, 3%-4% When -10 -15Degrees Celsius, 4%-6% 2. This product must do the powder directly to mix into the use, the negative warm time strict control uses the water volume, the adaption to lengthen stirs the time; 3. Takes shape the concrete to be supposed promptly to maintain; 4. Before the suggestion use, first uses this with to use the cement and the aggregate does tries to match the experiment, determined best mixes the quantity; 5. This product is 25kg weaves the bag packing, depositing is dry place, and is far away the fire hazard, the storage time 2 years. 6. This product does not have to use in the potable water project.
