Development of high functional materials from spheroidized scallop shells crystals

试图利用球化扇贝壳晶体作为颜料、复合材料和混凝土材料。以市售碳酸钙为原料制备的扇贝壳在白度、耐水性、pH值等方面与白色颜料无明显差异，可作为颜料使用。此外，我们试图通过创建有机-无机复合材料层和层压来创建具有高强度的薄膜材料。复合层是成功创建的，但没有获得足够的强度，因此有必要增加层数，作者认为。我们发现，当使用球化晶体作为添加剂时，水泥浆体的流动性得到改善，并且观察到由粉煤灰产生的球轴承效应。

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.
