Due to the important contribution of concrete superplasticizer modified terms, after its application to become reinforced and prestressed concrete, concrete history of the development of the third major breakthrough. In the development and application of superplasticizer as a symbol, the concrete technology into a plastic, dry and hard to fluidized third generation. In the early 1990s, the United States first proposed the concept of high-performance concrete (HPC), which called for concrete with high strength, high mobility, high durability performance of polycarboxylate liquor production, high performance concrete to a higher water reducer demands to superplasticizer having a water reducing rate, high fluidity and slump loss and other small features over time. Some new superplasticizer got rapid development and application of Kunming-acid liquor, such as poly shuttle acid-based, amino acid based superplasticizer. If the Fe-Al tetra-calcium content is high, it is relatively slow rate of hydration is also adsorbed more water reducer, and tricalcium aluminate hydration resulting crystals consumes more water, leading to its fluidity is reduced. Form gypsum cement impact on retention fluidity Polycarboxylate great, if more than half the water content of the plaster, gypsum reacts with water it consumes more water, so that the net loss quickly paste fluidity . In addition to cement, concrete raw fly ash, slag, stone and clay have a significant impact on superplasticizer application performance. Adding fly ash and slag of better help to improve the initial mortar flow and liquidity retention.
