Unconfined Compressive Strength Characteristics of Overboulder Asbuton and Zeolite Stabilized Soft Soil

Soft soil was one of the most widely encountered problems in construction, especially for archipelago countries which its area lowland with a high deposit soft soil. To overcome this problem, stabilization used as solution. Soil general uses chemical substances that are classified pozzolan material. Pozzolan material capability to strengthen cohesion grains. Mostly, consists silica. Overboulder asbuton and zeolite were examples natural Indonesia. Both materials have silica content. Thus, author interested figure out mechanical behavior these two stabilizer. This research correlating study previous paper same discusses overboulder added mix is determined 15%, varied percentages applied examine differences. The UCT conducted according ASTM D-2166 parameter. As standard remolding method, proctor test determine optimum moisture content maximum density each mix. While specimens tested at certain curing time composition. 0, 7, 14, 28 days. By period, effective pozzolanic reaction occurs composition could be determined. result shows addition increase compressive strength. It indicated proper alternative Doi: 10.28991/cej-2021-03091635 Full Text: PDF
