| Abstract | ||
| This research aims to improve the cohesion forces , thermal and mechanical properties and reducing cost for epomort epoxy adhesive by addition tarcoat epoxy adhesive as blends with ratio (25 , 50 , 75 V %) . The results of bending strength testing , compression strength testing and shore A hardness increasing for 75 % epomort + 25 % tarcoat epoxy adhesive blends more than 100 % epomort , 50 % epomort , 25 % epomort and 100 % tarcoat epoxy adhesive blends .The results of adhesion strength testing between concrete – epoxy adhesive blends at 25 oC and -2 oC show the failure has taken place in concrete , while at 90 oC the failure has taken place in concrete for 75 – 50 – 25 % epomort and 100 % tarcoat epoxy adhesive blends except 100% epomort epoxy adhesive the failure has taken place in epoxy adhesive . The crystallization temperature (TC) , melting temperature (Tm) and decomposition temperature (Td) of all ratio epoxy adhesive blends are converged or nearby . Reducing cost of epomort epoxy adhesive with addition tarcoat epoxy adhesive as blends by ratio ( 25 , 50 and 75 %) . The 75 % epomort + 25 % tarcoat epoxy blend gives better mechanical properties , thermal properties and low cost | ||
