Abstract:
The main objective of this laboratory project is to investigate the effectiveness of using polyvinyl acetate grout injection on fine graded sand improvement. Soil samples with different dry densities in their loose, medium and dense state (cylindrical shaped) with 5cm diameter and 10cm height are subjected to polyvinyl acetate injection. In order to investigate the grout injection effect on soil's strength, the specimens are subjected to one dimensional unconfined compression tests. It has been observed that by increasing the polymer percent in polymerwater mixture grout, the soil compressive strength and elastic modulus has been improved significantly. Denser sands presented higher compressive strength and elastic modulus in comparison with looser ones in same polymer percents
