Unconfined Compressive Strength Of Sedimentary Soil Stabilized With Portland Cement With Varying Curing Time

Soil improvement is commonly carried out in construction work with the aim of increasing bearing capacity / strength soil so that it can carry load will stand on it. The method often used stabilization addition materials. In this study, was Portland Cement. This research begins sampling and laboratory testing to determine physical mechanical properties soil, followed by making samples for Unconfined compressive 3 variations cement, namely 5%, 10%, 20%. From results known sample has a moisture content 97.13%, specific gravity 2.51, liquid limit 33.80% plasticity 22.52% plastic index value = 11.28%. Based classification system USCS (Unified Classification System) method, sedimentary types include CL (Clay-Low) types, clays low values. without portland cement obtained 0.352 kg/cm2. And stabilized various Cement highest 14.45 kg/cm2, + 20% 28 days curing time. showed dredging dam bili-bili tends increase its percentage time, category hard consistency be building structures road base soils.
