Development of high functional materials from spheroidized scallop shells crystals

作者尝试将球化扇贝贝壳晶体用作颜料、复合材料和混凝土材料。研究发现，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值等方面没有差异，可以作为颜料使用。此外，我们试图通过产生有机-无机复合层并将其层压来产生具有高强度的膜材料。作者推测，复合层成功地形成，但是没有获得足够的强度，因此有必要增加层数。我们发现，当球化晶体用作添加剂时，水泥浆体的流动性得到改善，并观察到粉煤灰所产生的滚珠效应。

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.
