説明
We have been investigating the geological origin, crystal structure, hot properties and refractoriness of 4 foundry silica sands in Tōkai district; Mikawa Synthetic Silica Sand, Seto Conical Silica Sand, Seto Natural Silica Sand and Chita Beach Sand. <br> Now we report the result investigated by crashing of these silica sands at room temperature. Crashing method is the shock-crashing by ramming. The grain sizes of these sands are 35, 48, 65, 100 and 150 mesh. <br> The gists of the experiments are as follows: <br> 1. The crashing of these silica sands at grain size and kind has each characteristic. <br> 2. We found that these characteristics are closely connected with the geological origin of each silica sand. <br> 3. The smaller the grain size of silica sand is, the more the difference of the crashing of these silica sand decreases. <br> 4. As for Synthetic Silica Sand, Conical Silica Sand and Natural Silica Sand, the bigger the grain size of these is, the more easily they crash.
