日本用聚酯纤维制成一种纺织物用于混凝土养护,施工时置于混凝土表面,可使混凝土构筑物质量大大提高,寿命显著延长。原来,这种有如滤布的纺织物,由于具有大量孔隙,使得混凝土在浇灌震动中,过量的水分及空气很容易排除;并能获得极光滑的表面。减少混凝土中的水分与空气量能提高其抗
Japan uses a polyester fiber made of a textile for concrete curing. When it is placed on the concrete surface during construction, the quality of the concrete structure can be greatly improved, and the service life can be significantly extended. Originally, textile fabrics such as filter cloths, due to their large number of pores, made it possible for water to evaporate and excessive moisture and air to be easily removed, and to obtain a very smooth surface. Reducing moisture and air in concrete can increase its resistance
