Cement-based material with shell-like bionic structure and preparation method of cement-based material
The invention relates to the technical field of preparation of cement-based materials, and provides a cement-based material with a shell-like bionic structure and a preparation method of the cement-based material. 25 to 40 parts of a gel agent; 0.1 to 0.8 part of a defoaming agent; 3-6 parts of a toughening agent; and 1-5 parts of a reinforcing agent. The preparation method comprises the following steps: mixing the shell powder, the gel, the defoaming agent, the flexibilizer and water to obtain a mixture; injecting the mixture into a mold, and carrying out first curing treatment to obtain a hardened sample; the reinforcing agent is brushed on the surface of the hardened sample for second maintenance treatment, and the cement-based material of the shell-like bionic structure is obtained. According to the cement-based material and the preparation method thereof disclosed by the invention, the special structure of the pearl layer of the shell is utilized while the waste shell is utilized, the mechanical property of the cement-based material is enhanced, and the durability is improved under the action of the reinforcing agent.
本申请涉及水泥基材料制备的技术领域，提供了一种类贝壳仿生结构的水泥基材料及其制备方法，其中水泥基材料包括以下质量组分：贝壳粉30～60份；凝胶剂25～40份；消泡剂0.1～0.8份；增韧剂3～6份；增强剂1～5份。制备方法包括以下步骤：将所述贝壳粉、所述凝胶剂、所述消泡剂、所述增韧剂与水进行混合处理得到混合物；将所述混合物注入模具中进行第一养护处理得硬化试样；将所述增强剂涂刷于所述硬化试样表面进行第二养护处理，得所述类贝壳仿生结构的水泥基材料。本申请的水泥基材料及其制备方法，对废弃贝壳的废物利用的同时，利用了贝壳珍珠层的特殊结构，增强了水泥基材料的机械性能，在增强剂的作用下提升了耐久性。
