Sea sand modifier and preparation method thereof
The invention provides a sea sand modifier and a preparation method thereof, the sea sand modifier comprises polypropylene fiber and wood ceramic in a mass ratio of (1-2): (3-6), the length of the polypropylene fiber is 5-7mm, and the wood ceramic is crushed to 150-250 meshes. The polypropylene fiber and the wood ceramic are matched for modifying the sea sand, the cement is added for curing, the obtained test piece has good unconfined compressive strength, cohesive force, deformation resistance and high damping ratio, the usage amount of the fiber is reduced, meanwhile, wood processing waste is fully utilized, and the method is green and environmentally friendly and has good application prospects. The sea sand can be used in practical engineering construction, and has important significance for development and utilization of marine resources in China.
本发明提出了一种海砂改性剂及其制备方法，包括质量比为1～2：3～6的聚丙烯纤维和木陶瓷，其中，聚丙烯纤维的长度为5～7mm，木陶瓷粉碎至150～250目。本发明通过选用聚丙烯纤维与木陶瓷搭配用于改性海砂，加入水泥养护所得试件具有较好的无侧限抗压强度、粘聚力、抵抗变形能力和高阻尼比，不仅降低纤维的使用量，同时也充分利用了木材加工废料，绿色环保，可使海砂用于实际工程建设中，对于我国海洋资源开发和利用具有重要意义。
