This paper presents the mechanical properties and performance of polyester grout as infill material for grouted connection in precast concrete. The mix proportions of polyester grout was properly designed and manufactured. The polymer binder with polymer additive was added together with filing materials of sand and fly ash. The binder to filler ratio was 0.43. Properties such as flowing ability and compression strength were studied by varying the level of fly ash in the mixtures. Also, to assess the efficacy of polyester grouted connections, three grouted connections were tested in direct tension. The test results show that, polyester resin grout with binder to filler ratio 0.43% and 16% fly ash perform satisfactorily. The polyester grout is suitable for use in the steel pipe splice connections.
