Abstract This study evaluated the chemical composition and microhardness of human enamel treated with an Enamel Matrix Derivative (EMD) solution, bond strength between composite resin this enamel. Thirty samples were randomly divided into three groups: Untouched (UE), Demineralized (DE) Treated EMD (ET). DE ET groups subjected to acid challenge (EMD was directly applied over conditioned left fo...

This paper explores a set of new equations to predict the bond strength between fiber reinforced polymer (FRP) rebar and concrete. The proposed equations are based on a comprehensive statistical analysis and existing experimental results in the literature. Namely, the most effective parameters on bond behavior of FRP concrete were first identified by applying a factorial analysis on a part of t...

bonding brackets to the enamel surface has gained much popularity today. new adhesive systems have been introduced and marketed and a considerable increase in research regarding bond strength has been published. a considerable amount of these studies deal with shear bond strength of adhesives designed for orthodontic purpose. previous studies have used variety of test designs. this diversity in...

poor adhesion between two successive bituminous layers causes adverse effects on the structural strength of the pavement and develops a numbers of premature failure. to improve the adhesion, it is a general practice to apply a tack coat over an existing or newly constructed bituminous surface before laying another bituminous layer. the main objective of this study is to explore the influence of...
