Abstract: 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 .

Key words: nanosilica;lime;modification;property
