Based on experimental study,the paper points out that the developed high effi cient concrete plasticity-maintaining agent named BS1 is suitable to the premixed high strength flowing concrete which mus be transported for a long distance.
YNB super plasticizer has the high performance of ratio of water reduction which is 30%,and the function such as superplasticity,adhesiver,thicker,reinforce etc.

Through the research of the physical and mechanical properties of the self leveling mortar, The authers developed a super flowing agent. The self leveling mortar with this flowing agent has a higher leveling property and longer workable time than ever. Its flowing diameter could reach to 240 mm, its workable time is within one and two hours, and its compression strength is more than 60 MPa. It can also increase the early strength and reduce the shrinkage by adding a certain amount of reinforcing material.
New type superplasicizer, compcsed of sulphonated naphthalene-formaldehyde condensates and some other chemicals, car resistant slump loss greatly and has a good compatbility with cements of different types. We usde it to the steel tube pumping concrete which has high strength and self-compacting successfully.
