  The invention relates to a reinforcing strip applicable in reinforced concrete, more particularly prestressed concrete, formed by a matrix based on a thermosetting synthetic material in which preferably more than 15000 practically parallel continuous filaments are obtained. The filaments are formed from an organic polymer selected from the group of aromatic polyamides, such as polyparaphenylene terephthalamide, or from polyethylene, polyvinyl alcohol or polyacrylonitrile via solvent spinning. The matrix is formed from a synthetic material based on epoxy resin and/or bismaleimide resin. The reinforcing strip has an improved resistance to alkali. The invention also relates to reinforced concrete comprising said strips.

  本发明涉及一种适用于钢筋混凝土，特别是预应力混凝土的增强带，它是由一种基于热固性合成材料的基体形成的，在这种基体中，最好能获得超过 15000 根实际上平行的连续细丝。 这些细丝是由选自芳香族聚酰胺（如聚对苯二甲酰胺）或聚乙烯、聚乙烯醇或聚丙烯腈的有机聚合物通过溶剂纺丝形成的。 基体是由基于环氧树脂和/或双马来酰亚胺树脂的合成材料形成的。 这种增强带具有更好的耐碱性。 本发明还涉及由所述增强带组成的钢筋混凝土。
