Shape of grains in sand and concrete aggregate. Current studies using image analysis
Abstract Two-dimensional, individual determination of projected sand grains have rapidly been made with the PICAP-system, a programmable picture processor. The grains are distributed in a stable position for determination, in the projection, of their length (L), width (B), area (A) and perimeter (P). From these measurements some shape factors are derived. The evaluation of our measurements of some concrete aggregates were carried out together with the Swedish Cement and Concrete Institute. Generally, there was found to be a good correlation between the results of the image analysis of the grains and their suitability for concrete; flat quartzite grains being an exception. Thus, we are studying the construction of an instrument for measuring all three grain dimensions.
