Research Progress on Durability of Cellulose Fiber-Reinforced Cement-Based Composites

The performance of cellulose fiber-reinforced cement-based composites (CFCCs) depends not only on the characteristics cement matrix and fibers but also bonding property fibers. durability including various properties such as impermeability, frost resistance, carbonization resistance has an important impact long-term service life structure. presence a large number hydroxyl groups molecular chain can promote formation intra- intermolecular hydrogen bonds cellulose. This special structure imparts high hydrophilicity, which leads hydration C-S-H gel to adhere surface cellulosic (CFs) induce its growth. cavity CFs good water absorption be used internal curing fiber for continuous composites. But in Portland tend deteriorate under strong alkali conditions. paper presents review research CFCCs. methods paths improve CFCCs are summarized analyzed from perspectives CFs, deterioration matrix, use many types supplementary cementitious materials. Finally, development engineering application have been prospected.
