| Research Abstract |
Self-healing function of sand cemented by calcium carbonate precipitation is presented. Cyclic undrained triaxial tests to clarify this function indicate that curing for a few days is not enough to recover of liquefaction resistance of destructed sand cemented by 1%. wt calcium carbonate, but increase in the amount of calcite precipitation gives self-healing function to sand.
