This paper presents the study on the properties of high-ductility fiber reinforced concrete\nmade with desert sand from Chinaâ??s Mu Us desert. The workability and uniaxial tensile/compression\nproperties of undisturbed desert sand-based fiber reinforced concrete (DS-FRC) with the change\nof water-to-binder ratio (W/B), sand-to-binder ratio (S/B) and desert sand replacement rate (DSRR)\nwere experimentally investigated. Experimental results reveal that the appropriate W/B and\ndesert sand content are conducive to the workability development of DS-FRC. The uniaxial\ntension/compression properties of DS-FRC are mainly affected by the W/B. Especially, the highest\nuniaxial tensile/compression stresses and corresponding strains are obtained at the W/B of 0.29.\nThe S/B has similar effects on the uniaxial tensile/compression properties, and an S/B of 0.36 is the\noptimal ratio. In terms of the DSRR, it shows less effect on the uniaxial tensile/compression properties,\neven for the DSRR of 100%. The results of the tests indicate that undisturbed desert sand can be used\nas silica sand in high-ductility fiber reinforced concrete.
