High Cement Content Soil Improvement Agent MT Series [Construction Case Studies] Infrastructure Development Project

Optimal for the field! A case where excavation for waterway widening was adopted in the infrastructure development project.

This construction project is a land readjustment project aimed at the large-scale consolidation of rice paddies. In this project, the initial plan was to backfill the existing waterway with locally generated soil for agricultural use. However, due to the high moisture content of the locally generated soil, we considered methods for soil improvement, but using cement or lime was not feasible due to concerns about their impact on crops. Therefore, we conducted trial mixtures to see if the high-water-content clay soil improvement agent MT-2 could be used. As a result, all soil environmental standard component analysis items were below the standard values, and the soil hardness (Yamanaka method) was determined to be 12mm after 21 days, leading us to conclude that backfilling with improved soil was possible, and we proceeded with mixing at the site of the existing waterway. Furthermore, considering future subsurface drainage and agricultural practices, the use of improved soil was limited to a depth of 80cm below the surface. Subsequently, improved soil was also utilized in adjacent construction projects. *For more details, please refer to the PDF document or feel free to contact us.*
