Abstract
The nano-sized CaCO3 filler material has unique properties caused by the large surface or mixed surface fraction with epoxy adhesives that can change the adhesive properties, especially viscosity, water absorption properties and increase adhesive strength. Therefore nano-CaCO3 filler is used as an epoxy adhesive mixture. The purpose of this study is to know the effect of nano-CaCO3 fillers toward the shear strength of carbon steel connections in dry and wet environments. The connection was made from carbon steel with epoxy as an adhesive. Heavy fractions of fillers nano-CaCO3 in adhesives 0%, 1%, 3%, 5%. The specimens were put into an oven for curing process with a temperature of 100oC for 1 hour then be continued by soaking for 70 days in distilled water at 28oC, 45oC and 55oC. The specimens were then shear tested in dry and wet conditions. The test results show that in dry and immersion conditions at temperatures of 28oC and 45oC the highest shear strength of the joints at 1 % nano-CaCO3 content was 18,64 MPa, 21,35 MPa, 19,98 MPa. Whereas in the 55oC immersion conditions the highest shear strength in the 5% nano-CaCO3 content was 13,78 MPa. Of all the conditions, the best performance of the adhesive occurred at 28oC while the worst performance was at 55oC. Overall adhesive failure in dry and wet conditions is interfacial, where interfacial failure can occurred in one side and two sides for all types of adhesives.
