Researches carried out in Benin allowed the use of Borassus aethiopum mart as reinforcement in concrete. The aim of this study is to examine the bond of the two materials. The results of pull out tests have shown that the bonding strength is around 1 MPa. This adhesion rate decreases slightly when the bond length increases; on the other hand, the adhesion rate increases slightly when the concrete strength increases. The behaviour of Borassus / concrete interface shows a first phase of perfect adhesion followed by a second phase of progressive loss of adhesion and a final friction phase which continues until the complete output of the reinforcement from the concrete.

Исследования, выполняемые в Бенине, подтверждают возможность использования волокон пальмы (Borassus aethiopum mart t) в качестве арматуры бетона. Изучение сцепления этих двух материалов есть цель представленного исследования. Результаты, выполненных экспериментов, показали, что сила сцепления составляет порядка 1 МПа. Показатели сцепления слегка пони-жаются, когда длина сцепления увеличивается, с другой стороны, показатели сцепления слегка увеличиваются, когда прочность бетона увеличивается. Поведение материала из волокон пальмы и бетона показывает, что в начале испытания появляется значительное сцепление, во второй фазе испытания следует прогрессирующее снижение сил сцепления и, наконец, финальная стадия испытания включает в себя выдергивание волокнистой арматуры из бетона.
