Rainfall erosion of natural fibers cement treated mud

Tóm tắt

This study evaluated the possible application of inexpensive mud stabilization treatments  for the purpose of reducing soil erosion. The soil erosion was investigated by measuring  soil loss over the surface of compacted specimens made by natural fibers cement treated  mud exposed to a rainfall test sequence. The compacted specimens were made by adding 5  kg/m³ to 50 kg/m³ cement and 0 kg/m³ to 20 kg/m³ natural fibers to 40% to 60% water  content mud. The results showed that the increasing of either cement content or natural  fibers  content  reduced  the  soil  erosion  from  50%  to  80%.  Furthermore,  a  numerical  function was developed to predict the value of soil loss of the treated mud based on the  ratio of cement content, natural fibers content and initial water content.
