て、破断時に繊維がマトリックスから引き抜けるために
充分な補強効果が発揮されない。In general, the surface of organic synthetic fibers is hydrophobic and therefore has extremely poor adhesion to the hydrophilic cement matrix. Therefore, the fibers are pulled out of the matrix upon breakage, and a sufficient reinforcing effect cannot be achieved.
繊維の引き抜きを防止するために繊維の断面を異形化し
たり長さ方向に突起や節をつけて摺り抜けない工夫がと
られているが根本的にマトリックスとの接着性が悪いこ
とから満足すべき結果は得られていない。In order to prevent the fibers from being pulled out, measures have been taken to make the cross section of the fibers irregular and to add protrusions and knots in the length direction so that they do not slip through, but this should be satisfied since the adhesiveness with the matrix is fundamentally poor. No results have been obtained.

Among these fibers, steel fibers have a good affinity with cement and therefore have good adhesion to the matrix, but the expansion caused by rusting of the steel fibers causes a decrease in adhesion and strength. It has its drawbacks.

効果が発揮できない。In recent years, studies have been conducted on fiber-reinforced cement mortar and concrete compositions using organic synthetic fibers that can solve these problems. However, since these fibers are hydrophobic, they have poor adhesion to the cement matrix, and when broken, the fibers can be pulled out of the matrix, making it impossible to achieve a sufficient reinforcing effect.
