Abstract
This work is dealing with the effect of percentage of inactive fines on the characteristics of coarse-grained soil. The soil used in this research are medium sand have a uniformity coefficient of 2.77 and the fine material used is classified as medium plastic silt haveing consistency limits : L.L =31.4% , P.L = 13.7%, Sh.L = 12.3%.
Laboratory testing program had been established to
determine all the physical and mechanical properties of the sandy soil.
The variables investigated are Percentage of fine : (0 , 20
and 50o/o).,Initial water content : (dry and wet of the optimum), Initial density: (max dry density and 95% of the max. dry density ), Flooding with water at certain specific stress.
The results are presented in the form of Compaction
curves, Compressibility curves, Stress- displacement curves, Normal stress- shear strength relationships, Penetration resistance- water content relationships, Compaction field results (penetration resistance results).
The maximum dry densities as well as the optimum water content were determined for the different fine content. The shear strength Parameters ( C and ) are determined according to Mohr-Coulomb failure criteria are calculated. The suitability of the cone penetrometer as a tool for quality control of compaction is examined .
