The aim of the study was to determine the value of Unconfined compressive strength after stabilizing the black cotton
soil with cement and with combination of cement and polypropylene fibre. In this study laboratory experiments were conducted
to evaluate the effect of using polypropylene fibre to enhance the strength of cemented black cotton soil. Three fibre polymer
contents were used (0.3, 0.6 and 1% by dry weight of the soil) to examine the unconfined compressive strength of black cotton
soil mixed with three different cement contents (5, 10 and 15%). For broad interpretation of the fibre reinforced soil-cement
behaviour several factors were considered in this study such as time period (3, 7 and 28days) and at water content 35 %
