This paper reviews the basic nature of the cement-aggregate bond and its effects on concrete performance. The bond is a result of mechanical interlocking provided by epitaxic growth of cement hydration products on the aggregate surface and of chemical reactions between the cement paste and aggregate

β¦ Synopsis
Research on the structure and bond between cement stone and aggregates shows that the structure of the contact zone clearly di#fers from that of the plain cement stone. The main constituent of the contact zone seems to becalcium hydroxide which is also mainly responsible for the cement-aggregate bond.

On the basis of the knowledge about the contact zone between aggregate and cement stone researches were carried out with the aim to enlarge the bond strength of these components. The researches lead to an increase of bond strength to such an altitude, that at the age of one year the tensile strength
