Concrete self-curing anti-cracking fiber bundle and application method thereof
The invention belongs to the technical field of engineering materials, and provides a concrete self-curing anti-crack fiber bundle and an application method thereof. The concrete self-curing anti-cracking fiber bundle comprises a water-absorbent resin microrod and a plurality of single fibers, forms a space structure in which a plurality of single fibers are spirally bundled and wrap the single water-absorbent resin microrod, and can form a'micro reservoir 'in concrete when being applied to the concrete, so that the anti-cracking performance of a concrete structure is improved, and the concrete self-curing anti-cracking fiber bundle has a good anti-cracking effect. The generation of plastic cracks in the concrete setting and hardening process is effectively inhibited; meanwhile, the self-curing function of the concrete structure in the hydration process is achieved, shrinkage cracks caused by water loss of the concrete structure are relieved, and the durability of the concrete structure is improved.
本发明属于工程材料技术领域，本发明提供了一种混凝土自养护抗裂纤维束及其应用方法。该混凝土自养护抗裂纤维束包括吸水树脂微棒和多个单根纤维，形成了多个单根纤维螺旋集束包裹单根吸水树脂微棒的空间结构，应用在混凝土中，可在混凝土内部形成“微型蓄水池”，不仅提升了混凝土结构的抗裂性能，有效的抑制混凝土凝结硬化过程中塑性裂缝的产生；同时还实现了混凝土结构在水化过程中的自养护功能，缓解了混凝土结构因失水而造成干缩裂缝的产生，提升了混凝土结构的耐久性。
