废弃贝壳在建筑材料中的应用

Application of abandoned shells in building materials

我国具有辽阔海疆和发达的水产养殖业,每年产生的大量废弃贝壳对水源、耕地和空气造成了严重的污染。贝壳粉属于可再生的生物矿化材料,具有防火阻燃、杀菌抑菌和吸湿调湿等功能特性,极具研究价值和应用前景。介绍了贝壳的结构特性及其在建筑材料领域的研究、应用情况,对贝壳粉产品的后续开发和应用有一定的借鉴意义。

China has a vast sea areas and developed aquaculture industry. In such cases, the large amount of aban-doned shells produced each year has caused serious pollution to water, cultivated land and air. Shell powders are re-newable biomineralized material with functional properties, such as fire retardant, bactericidal and bacteriostatic,moisture absorbing and humidity control, which has great research value and application prospects. The structuralcharacteristics, research status and application prospects of shell powders are introduced in this paper, it has certainreference significance for the subsequent development and application of shell powder products.
