Abstract
We investigated relation between the consolidation by the colloidal clay particles and size of sand particles in the sand base. Consequently, the following results were obtained.(1) The marine mud in which colloidal clay contents were rich and humus contents were little, were suitable to effects of the consolidation and the impermeability in the sloping salt-field.(2) Good results were obtained for sand having a permeable coefficient between 101-5-10-6.
