Compression strength testing model on clay soil stabilization using variations of cement composition

Abstract

The title of this study is «Compression Strength Testing Model on Clay Soil Stabilization Using Variations of Cement Composition». The focus of this test is the addition of different compositions of cement and clay. Composition of this test is 100% soil + 0% cement, 70% soil + 30% cement, 50% soil + 50% cement and 30% soil + 70% cement. The next stage of drying is done for 0 days, 5 days, 10 days, 15 days and 20 days. The test is performed by unconfined compression test machine for each sample dried within the time specified above. The cement used is Portland composite cement type (Portlant Cement Composite / PCC). The conclusion is obtained from the results of tests that have been done that the soil composition of 100% + 0% cement land indicates if the longer drained the value of the compressive strength will decrease. However, in the other composition 70% of soil + 30% cement, 50% soil + 50% cement and 30% soil + 70% cement show that the longer drying is done for each composition the relationship between strain and stress shows an increase along with the duration of drying done. However, if analyzed for the largest compressive strength value of this test was found in the 50% + 50% cement sample showing the largest compressive strength (q u ) compared with the other samples.
