交流借鉴：浅谈风化砂及机制砂对混凝土性能的影响
15 Jul 2022 风化砂是地表岩层风化过程的产物。由于风化砂的特征是颗粒呈棱角状、空隙多、强度较弱、粒径分布不均匀、质地软，造成其耐久性较差、吸水性大、物理力学性 生产流程：风化砂经由振动给料机送入颚式破碎机的破碎腔中进行粗碎加工，后符合规格的进入制砂机中进行制砂、整形处理，不合规格的再次返回至颚破中进行二次加工直至达 风化石可以制砂吗？利润高吗？ 知乎

风化与侵蚀 – 地貌过程导论
20 Oct 2021 某些岩石﹝例如花岗岩及粗粒凝灰岩﹞经过风化后，会形成厚厚的风化层，其特色是在含有粉砂、黏土及沙粒物质结集成的弱风化土中，出现圆形的巨砾﹝岩石核﹞。 这含有岩石核的风化层是香港岛及九龙 风化砂的特征是颗粒呈棱角状，强度较弱，大小分布不均匀性较大，并含有一量的细土粒。 河沙成分较为复杂，表面有一定光滑性，杂质含量多。 河沙颗粒圆滑，比较洁净，来源 风化砂和河沙的区别是什么？百度知道
石头能变成沙子吗？ 知乎
含有硅酸盐的石头，经过风化作用变成沙子，化学组成不会发生明显变化。 ，其实不难发现含量最多的化合物应该是二氧化硅。（但是不是一定要有硅酸盐的石头才能风化成砂粒，例如硅质岩的主要成分有石英、玉髓和蛋白石（主要化学成分均为二氧化硅 Abstract： Centrifugal modeling technology has been applied to geotechnical engineering for more than half a century It has been an important and indispensible means to simulate the geotechnical behavior because it can reflect the actual stress levelApplication and Development of Centrifugal Modeling Technology
