It can work well with other chemicals and produce early strength agent, slow setting agent, antifreeze and pumping agent . It is widely used in various concrete projects such preformed concrete, reinforced concrete and prestressed concrete, especially applicable for commercial concrete, anti-freezing concrete, waterproof concrete, bulk concrete, pumping concrete, with high economic benefit.Main performance:1,Can reduce 10% of water consumption at least ; 2, can improve mixture of the concrete;3, Compression strength improves by more than 15% equally on 3-28 days; 4, Have no function of corroding on the reinforcing bar.  Operation methods : 1. 0.2-0.5% of mixing amount in concrete (with cement weight), users can adjust the mixing amount through the test ; 2. Can use after mixed liquid , also can put with cement , aggregate into mixer to use at the same time too, need lengthen time properly; 3. the result is more obvious after mixing with high-efficient naphthalene department water-reducing agent. User can determine the suitable dosage according to the result that cement variety, aggregate situation, naphthalene department type of water-reducing agent are tested fixing; Packing, storage & transportation: 1, Packing: 25kg in PP woven bag lined with plastic film. 2,Storage: Kept in dry and ventilating place, prevent from rain and moisture when storage; if agglomerated, please crush and make it into solution, and its effect will be the same.
