| Abstract: | The aim of this work is to investigate the influence of silane coupling agents on the properties of vinylester resin and vinylester mortar. Research work is focused on two methods of modification: direct silane addition to the resin binder and the use of silane pre-treated silica flour as a filler. The results of such modification are described, taking into consideration mixture viscosity, curing conditions, mechanical strength and fracture process. The test results indicated that silane coupling agent can decrease the viscosity of the mortar mixture, extend its pot life, enhance its mechanical strength and resistance for fracture. However, changes in the curing process, which may be disadvantageous and the increase of composite brittleness were noticed and stressed. |
