✦ Synopsis

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 of cement stone was exceeded. For this purpose the aggregate surface had been covered by a suspension of pumice, detergent and water glass.

In pull out tes~with steel bars, which were covered with the suspension described above a remarcable increase of bond in concrete was obtained.

Low levels of insoluble aggregates in protein formulations can sometimes only be detected by visual inspection. To overcome the subjectivity and other limitations associated with visual inspection, a microscopic technique based on filtration/staining was developed. This method is a simple modificati
