Liquefaction Resistance of Sand-Kaolin Mixtures: Effect of Sand Sizes

Grading characteristics, particle sizes, shapes and fines content are the factors contributing to liquefaction incidents besides major such as earthquake magnitude. Recent publications reports from of liquefied or potential soils show some evidence that size sand particles, grading characteristics will increase decrease resistance. However, date results still disputed need be expanded. Hence, aim this paper is investigate effects different sizes in sand-kaolin mixtures on The resistance with application sand-coarse sand, medium fine mixed (kaolin) (0%,10%, 20%, 30%, 40%) investigated through a cyclic triaxial test under undrained conditions. Each reconstituted sample was prepared target relative density 15% (loose state) 5% initial moisture for test. Effective consolidation pressures 100 kPa were applied tests. Microstructure analysis soil samples carried out explain behaviour tested. centrifuge selected so actual conditions could visualised. clearly reduced at sizes. At constant each parent decreased an up certain percentage, then increased thereafter. f th 30% 20% outcomes study useful advance understanding design purposes.
