摘要
硅烷偶联剂浓度对改性再生塑料混凝土的力学性能影响较大.本实验通过选取不同浓度的硅烷溶液来处理再生塑料颗粒,并将其掺入混凝土中,制成所需规格的试件,测定其立方体抗压强度、劈裂抗拉强度、轴心抗压强度以及抗折强度.实验结果显示,再生塑料颗粒含量较少时,硅烷浓度对力学性能影响不大;随着再生塑料颗粒含量越多,硅烷浓度对力学性能影响越大,且硅烷浓度大于1%时其力学性能增大幅度最大,之后随浓度增加基本保持不变。
The Silane coupling agent concentration has a significant effect on the mechanical properties of modified of recycled plastic concrete. The trial selects the different concentration of silane coupling agent for modifing the recycled plastic particles,which is mingled with concrete,gets the suitable specifications of concrete block and then tests the concrete block of compressive strength,splitting tensile strength,axial compressive strength and flexural strength. According to experimental results,the less content of recycled plastic particles,silane concentration has the less influence on the mechanical properties of recycled plastic concrete,along with the more content,there is the more effect of silane concentration on the mechanical properties. With the silane concentration is greater than 1%,the mechanical properties greatly increase with the rising of concentration.
