PERFORMANCE OF RECRON-3S FIBER ON BLACK COTTON SOIL

Abstract This study deals with the stabilization of soils through the application of recron fiber. The main aim of this study is to determine the percentage of recron fiber that would be added to black cotton soil to obtain the optimum stability of the soil. In order to achieve these, the following tests are carried out; pycnometer test, casagrande's test, proctor compaction test, sieve analysis, unconfined compressive strength test. The soil index tests are carried out. Compaction test is carried out in order to determine the maximum dry density and optimum moisture content of black cotton soil. Specific gravity of soil is also determined as to know the index experiments values and lastly, unconfined compressive strength test should be carried out to determine the compressive strength of black cotton soil sample. Then unconfined compressive strength is repeated to the soil sample along with the addition of recron fiber and cement separately in percentages as a stabilizing agent. After carrying the above tests, observations are to be noted and results are calculated. A perfect material for the given sample is recommended for maximum stability. Key words: Recron fiber, Compaction, unconfined compressive strength, stabilizing agent.
