    Abstract：Through the test of the index such as fluidity，flow velocity，loss of fluidity and strength of the high strength concrete which is mixed with MPEG，APEG，TPEG，HPEG and VPEG type of polycarboxylate superplasticizer，the performance characteristics of the high strength concrete which is mixed with different types of polycarboxylate superplasticizer has been investigated. Experimental results show that the C60 concrete which is mixed with PC1 of APEG and PC5 of VPEG has better construction performance.
