On the strong dispersion of cement, reduce water quality HS, improve the strength of concrete in each age. 2). Substantial increase the slump and expansion of concrete, improve the performance significantly. 3). Basically does not change the setting time of concrete, can significantly increase the early strength of concrete. 4). Anaerobic and low-alkali, no corrosion to the reinforcing steel, could prevent alkali-aggregate reaction effectively. Applicable scope: 1). All kinds of Strength Concrete. 2). Flowing concrete. 3). Early strength concrete. 4). Prestressed concrete. 5). Ready-mixed concrete. 6). Autotrophic or steam precast. Using the methods and Precautions: 1). Usefull content is 0.5-1.5% of cement materials, water-reducing rate is 12-25%. 2). To maintain the same concrete strength and slump, can save 10-20% cement. 3). Combined with the other groups, can prepare a variety of performance additives; such as early strength water-reducing agent, retarding water reducer, pumping aid, antifreeze, water. etc, could meet all types of projects. 4). Packing is 40kg±0.25kg/PP bag. In the transport and storage, should be noted that rain water and moisture. In the dry state, valid for 2 years. Superplasticizer can still be used after passing through the detection when expired.
