纳米微晶纤维素应用于水泥基材料研究综述

Research Progress of the Application of Nanocrystalline Cellulose in Cement-based Materials

由于纳米微晶纤维素(nanocrystalline cellulose,NCC)具有高模量、极高长径比和大比表面积等特性,近几年来NCC在水泥基材料中的应用成为了研究前沿和热点。虽然NCC在水泥基材料中的应用研究还处于初级阶段,但却为改善水泥基材料性能提供了一个新的研究方向。本文综述了近几年国内外对NCC在水泥基材料中的应用研究,主要介绍了NCC在水泥基材料中的存在形式,及其对水泥基材料的流变性、水化、力学性能和耐久性的影响。最后,分析了NCC在研究中存在的问题,并对NCC今后的研究方向给出了可行性建议。

Nanocrystalline cellulose（NCC）in recent years becomes the frontier and hot point due to its high modulus,high aspect ratio and specific surface area.Although the application of NCC in cement-based materials is still in its infancy,it provides a new research direction for the modification of cement-based materials.In this paper,the form of NCC in cement-based materials,and its effect on rheological property,hydration,flexural strength and durability of cement-based materials are mainly introduced.At last,the present problems in current study are pointed out and some positive proposals for future research are put forward.
