| Summary: | Water content in soil depends on the soil porosity because each soil has its own characteristic soil-water retention. This study was done to compare the effects of
different moisture content on aggregated soil structure as, well as to investigate the effect of different moisture content on soil strength in aggregated soil. Type S22 kaolin powder was used to create the aggregated soil samples in the laboratory. Separate aggregated soil samples were created for moisture contents of 43%, 45% and 47% in order to evaluate the effect of moisture content difference on the aggregated samples. Environmental Scanning Electron Microscope (ESEM) was used to obtain images of the aggregated soil structure and Unconfined Compression Test (UCT) was performed on
each sample to determine the strength of the aggregated soil. Based on the ESEM results, all the samples show double porosity features due to the compression of soil
aggregates but the sample with water content of 45% gave the best aggregated soil structure. Based on the UCT results, the sample with 47% water content showed the
maximum strength. |
