The pointing hardness tester — an instrument to meet a need
Abstract The quality of the pointing in recent brickwork is, at least in The Netherlands, often unsatisfactory. In the author's view an important cause may be that architects seem to be only interested in the aesthetic aspects of the pointing. Another significant reason may be, however, that until recently there was no effective method of measuring the quality of the work done. TNO Building and Construction Research (TNO-IBBC up to 1991) modified the Schmidt pendulum hammer P for plaster and aerated concrete. It can now be used by anyone in the building trade to measure the hardness of pointing in masonry— simply, quickly and reproducibly. The results are so good that the new measuring methodology deserves to be standardized. In anticipation of this a provisional classification is proposed based on several years' experience. The results of both laboratory investigation and practical work are presented.
