The mechanical properties of argil fly-ash concrete and effectiveness of its application to abutment-backfill are investigated by material experiment
centrifugal modeling test and numerical calculation. It is pointed that the properties of argil fly-ash concrete are superior to that of other backfill materials. Its properties have the advantages of light mass
high strength and high modulus. In addition
its construction method is different to that of other materials. Its soil pressure and settlement are smaller than that of other materials markedly. Consequently
the results indicate that the argil fly-ash concrete is recommendable backfill material.
