钢纤维混凝土具有抗拉、耐磨等高强性能特点,普通混凝土早期塑性收缩,干缩最为严重,早期养护尤为重要,钢纤维混凝土固然抗收缩性能很好,不等于不按正常的施工步骤来操作.主要是因为它的主要材料还是混凝土,钢纤维只是少量的掺入.所以做好钢纤维混凝土的早期养护工作直接影响工程质量的优劣。
Steel
fiber reinforced concrete has high-strength performance characteristics
such as tensile strength and wear resistance. Ordinary concrete has the
most severe early plastic shrinkage and dry shrinkage, and early curing
is particularly important. While steel fiber reinforced concrete has
good anti shrinkage performance, it does not mean that it does not
operate according to normal construction steps. The main reason is that
its main material is still concrete, and steel fibers are only added in
small amounts. Therefore, doing a good job in early curing of steel
fiber reinforced concrete directly affects the quality of the project.
为了使钢纤维混凝土得到广泛应用,一方面,在应用时,不应只计一次性投资,而应考虑钢纤维混凝土的****使用性能、较低的维修费和使用寿命延长等综合经济效益；另一方面,应努力降低钢纤维生产成本从而降低钢纤维混凝土的造价
In
order to make steel fiber reinforced concrete widely used, on the one
hand, when applying it, not only one-time investment should be
considered, but also comprehensive economic benefits such as the * * * *
performance, lower maintenance costs, and extended service life of
steel fiber reinforced concrete should be considered; On the other hand,
efforts should be made to reduce the production cost of steel fibers in
order to lower the cost of steel fiber reinforced concrete
随着钢纤维生产工艺的不断完善,可为广大消费者提供更多更好的产品,无论是在混凝土内部或外部,大裂缝,小裂缝,钢纤维能起到挡上效果很好,但效果是非常明显的,这些裂缝容易使钢纤维,但如果没有钢纤维,这些小裂缝,有可能成为一个潜在的具体的威胁。但是一些小型地下室工程应该考虑进去。防水,由于地下潮湿可能会对混凝土和钢纤维产生侵蚀,不仅要改善钢纤维、纤维表层,提高其耐腐蚀性能,还应在混凝土中加入防水材料,以便更好地利用混凝土。
With
the continuous improvement of steel fiber production technology, more
and better products can be provided to consumers, whether inside or
outside concrete. Steel fibers can effectively block large and small
cracks, but the effect is very obvious. These cracks can easily damage
steel fibers, but without steel fibers, these small cracks may become a
potential concrete threat. But some small basement projects should be
considered. Waterproofing, as underground moisture may corrode concrete
and steel fibers, not only should the surface of steel fibers and fibers
be improved to enhance their corrosion resistance, but waterproof
materials should also be added to concrete to better utilize it.
