Composite bionic aluminate cement-based material with high toughness and preparation method thereof
The invention discloses a composite bionic high-toughness aluminate cement-based material and a preparation method thereof.The aluminate cement-based material is formed by arranging and hot-pressing a plurality of semi-dry particles, and the arranged structure comprises a layer a formed by paving particles with the particle size a and a layer b formed by paving particles with the particle size b on the layer a, a layer c formed by paving particles with the particle size c is paved on the layer b, and the particle size a, the particle size b and the particle size c are different; the semi-dry particles comprise the following components in parts by weight: 500 parts of cement, 80 parts of water, 0-30 parts of PVA (Polyvinyl Alcohol), 0-5 parts of glycerol and 0-60 parts of Fe3O4. According to the method, semi-dry particles are prepared by adjusting the mixing proportion of cement materials, rearrangement and hot pressing are carried out to form a gradient'brick-mud 'structure, operation is easy, cost is controllable, implementation is easy, and compared with a control group, the tensile strength and bending toughness of the obtained cement-based board are greatly improved; the cement-based material with high strength and toughness can cover a wider application range.
本发明公开了一种复合仿生韧性强的铝酸盐水泥基材料及其制备方法，所述铝酸盐水泥基材料由若干半干颗粒排列后热压而成，所述排列的结构包括一层由a粒径颗粒平铺而成的a层，a层上平铺的一层由b粒径颗粒平铺而成的b层，b层上平铺的一层由c粒径颗粒平铺而成的c层，其中a粒径、b粒径和c粒径均不相同；所述半干颗粒的组分包括，按重量分数计，500份水泥、80份水、0‑30份PVA、0‑5份丙三醇、0‑60份Fe3O4。该方法通过在调节水泥材料的配合比制备了半干性颗粒并进行了重新排列热压形成梯度“砖‑泥”结构，操作简单，成本可控，易于实现，得到的水泥基板材较对照组抗拉强度和弯曲韧性有了极大提升，这种高强韧性的水泥基材料可覆盖更为广泛的应用范围。
