摘要
TRC永久模板因不需要钢筋保护层,其厚度可以很薄,由此给水泥基复合材料提出了更高要求。为了获得最佳性能的水泥基复合材料配合比,通过控制短切玻璃纤维掺量、水胶比和灰砂比研究水泥复合材料的抗压强度、抗折强度和劈裂抗拉强度。研究表明,纤维掺量对提高材料力学性能有较好的效果,但应控制其掺量在5%左右。水胶比0.33及胶砂比0.3时力学性能最好,水胶比过大容易引起泌水现象。
The TRC permanent template can be made very thin because it does not require a steel protective layer. Therefore, it puts forward higher requirements for cement composite materials. In order to get the best performance of cement base composite material mixture ratio, this article studies by controlling the chopped glass fiber content, water/cement ratio and cement composites compressive strength, flexural strength and splitting tensile strength, sand ratio.The results show that the fiber content has a good effect on improving the mechanical properties of materials, but it should be controlled around 5%. Hydroeolloidal ratio is 0.33 and cement-sand ratio is 0.3, and water-binder ratio is too large so as to cause bleeding.
