Microscopic evaluation of 1-D compression for air-form treated lightweight geo-material

摘要: A lightweight geo-material (LGM) for port construction has been developed as a value-added material, which is not only means of recycling dredged soil but also offers additional functions such improvement the earthquake-proof capacity by decreasing lateral earth pressure on seawall and prevention differential settlement overburden stress an underground structure. The deformation characteristics LGM due to its own weight superimposed structures were studied using scanning electron microscopes colour laser 3-D profile microscopes. Preparation air-foam treated described. void ratio minus log compression relationship showed reversed S-shaped curve similar that natural clay deposit with well-developed This could be properly evaluated from microscopic point view. one-dimensional compressibility qualitatively quantitatively view, in particular distortion bubbles. It considered possible match up cement hydration aging effect air-formed skeletal structure structure, providing model system deposit. For covering abstract see ITRD E128041.
