This research focuses on soils derived from volcanic ash in the city of Popayan, stabilized with low percentages of cement. The results reveal high variability in properties due to changes in moisture content, structural condition, and curing time. The study involved evaluating the physical and mechanical properties in both natural state and after modification with cement at 3%, 4%, and 5%. Natural state soils exhibit deficient conditions, such as subgrades or embankments, necessitating improvement in various cases. When cement is used as a stabilizer, it is possible to conclude that there is an increase in mechanical strength and marginal improvements in hydraulic properties (cement- modified soil). However, these improvements are not comparable to the significant enhancements observed after reaching a 5% cement content (soil-cement).
