RESEARCH OF SJN B ADHESIVES FOR STRENGTHENING CONCRETE STRUCTURE WITH CFRP

The technology of strengthening concrete structure with carbon fiber reinforced polymer ( CFRP) is one kind of emerging and high_technology reinforcement methods, as compared to traditional reinforcement methods it has obvious technical superiorities. But the quality of adhesives for CFRP is one of key fators that influence the widespread of CFRP.This topic used the epoxy resin as a primary stick and used the nitrile rubber as a plasticizing material and other materials,finally the adhesives for CFRP which conform to the technical idexes of CECS 146: 2003, are developed, which have good resistances to fatigue and ageing.
