Mechanical Property of Coal Ash Mixed with Clay

Article Preview

Abstract:

A series of tests were conducted with laboratory normal devices to investigate the engineering property of coal ash mixed with various clay contents. By analyzing experimental data, some conclusions were made: It is helpful to improve the compaction effect and significantly reduce the consumption of the water needed in engineering by mixing the clay into coal ash. The shear strength of coal ash decreased slightly with increase of clay content. The shear strength of coal ash mixed with the 30% clay content is nearly equal to that of pure coal ash. With the increase of clay content, the coefficients of compressibility a1-2 have a little irregularly growth. It always belongs to medium compressibility soils.
