Development of high functional materials from spheroidized scallop shells crystals

作者尝试将球化扇贝壳结晶用作颜料、复合材料和混凝土材料。结果表明，扇贝壳与以市售碳酸钙为原料的白色颜料在白度、耐水性、pH值等方面没有差别，可作为颜料使用。此外，我们还试图通过创建有机-无机复合层并对其进行层叠来创建高强度的薄膜材料。作者认为，复合材料层已成功创建，但没有获得足够的强度，因此有必要增加层的数量。研究发现，用球化晶体作外加剂，可以改善水泥浆体的流动性，并观察到了以飞灰为原料的滚珠效应。

The authors attempted to utilize crystals of spheroidized scallop shells as pigment, composite material and concrete material. It has been found that scallop shells are not different from white pigment with commercially available calcium carbonate as raw material in whiteness, water resistance and pH and can be used as pigment. Furthermore, we attempted to create film material with high strength by creating organic-inorganic composite layers and laminating them. Composite layers were created successfully however sufficient strength was not obtained therefore it is necessary to increase the number of layers, the authors presume. We have found that the flowability of cement paste is improved when spheroidized crystals are used as an additive and ball bearing effect, which is developed by fly ash, has been observed.
