| Abstract/Contents: | "Sands are widely used on winter games pitches both for construction work and maintenance. Sands should be selected according to specified criteria for the task in hand and then if a number of alternatives are available the relative cost of the different sands should be considered. Sands are used in construction because they can form a matrix of relatively large pores in the rootzone layer which remain stable even after the compacting effects of play. In choosing a sand for a rootzone layer there are a number of considerations. First the sand should be uniform in its size distribution. Second is to obtain a sand of the right size. The optimum size of a rootzone sand depends on the application. For some applications particle shape is very important, most notably for bunker sands for which the use of an angular sand increases the angle on the bunker face to which the sand can be raked and may also increase stability for footing and ball impacts. For slit drainage there are also major conflicts involved in the choice of a sand. If the sand is too coarse, it is virtually impossible to establish grass over the slits. The principles determining the choice of sand for top-dressing a winter games pitch are essentially the same as those involved in selecting materials for rootzone layer. The slight deviation which should be considered for a top-dressing sand, compared to a rootzone sand, is to reduce the amount of fines (particles of very fine sand, silt of clay <0.125mm diameter) as much as possible as these can accumulate at the immediate surface. Grain size and the uniformity of the size distribution can be determined using a sieve test. Lime content can be determined by adding a weak solution of hydrochloric acid. Grain shape can be determined using a microscope by comparing the grains and standard charts showing the angularity and sphericity of the particles." |
