纳米SiO_2对石灰基材料性能影响研究进展

Review on Effect of Nanosilica on the Properties of Lime-based Materials

作为一种应用广泛的无机纳米材料,纳米SiO_2颗粒尺寸小、比表面积大、表面吸附性强,在改性石灰早期强度低和耐久性方面效果显著。综述了纳米SiO_2对石灰基材料力学性能、耐久性以及改性机理等方面的研究进展,并基于上述综述提出了纳米SiO_2改性石灰基材料当前存在的问题,结合纳米SiO_2改性石灰的应用情况,展望了该类材料未来的发展方向。

As a kind of widely used inorganic nanomaterials,nanosilica,with markedly modification effect on the lime-based materials,has some characteristics such as small particle size,large specific surface area and strong surface adsorption. This paper mainly reviewed the research progress of mechanical performances,durability and modification mechanism of lime-based materials modified with nanosilica,proposed the current existing issues of lime-based materials modified with nanosilica based on the above reviews, combined with the applications of nanosilica modification lime, further prospected the development directions of this materials in the future.
