[1188] THE EFFECT OF LIQUIDITY AND SEGREGATION-RESISTANCE OF FILLING MORTAR
Keywords:filling mortar, aggregate, flow value, segregation-resistance, plastic viscosity
In the construction of retrofitting works with steel jacketing, there is a gap between steel plates and existing bridge pier or column, the anti-earthquake reinforcement would be provided by using filling material to fill up the gap. The fluidity and segregation-resistance property of filling material are the most important part to control the filling. However, it is relatively difficult to prepare and evaluate it. In this study, the evaluation of segregation-resistance property and the rheology of gap filling mortar was conducted on the basis of ensuring the fluidity of filling mortar.
