Bearing capacity (CBR) of three clay soils incorporating banana pseudostem fiber in different percentages

Abstract

The aim of this investigation was to determine the bearing capacity of three clayey soils incorporating pseudostem banana fiber in lengths of 25mm, in three different percentages: 0.25%, 0.50%, 0.75%, forming a homogeneous mixture with the soil. These additions raised the values of the soil bearing capacity indices, California Bearing Ratio (CBR). The incorporation of banana pseudostem fiber positively influenced the bearing capacity of the three soils, since with an incorporation of 0.25%, the CBR value for soil No. 01 increased by 50.78%; 220.27% for soil No. 02 and 31.73% for soil No. 03. Furthermore, decreases in the CBR index were observed when the fiber percentages increased.
