Abstract
The use of traditional techniques in geotechnical engineering often faces problems because of high costs and/or environmental issues. In Roads, for instance, the use of granular bases became unviable when the borrow site is far away from the construction site. Another example is the construction of foundations in soils with poor bearing capacities, where the costs of a deep foundation solution can be incompatible with the overall costs for low-budget building soil through the addition of cementitious agents or projects. In these cases, alternatives for the improvement of local soil through the inclusion of oriented or randomly distributed discrete elements such as fibers might be used and soil treatment/stabilization is often an effective approach for solving soil problems after considering whether the site conditions are possible for treatment, or to avoid the site where the soil properties are unsatisfactory. Based on the material’s origin and use in practice, stabilizers are divided into three groups: traditional stabilizers, byproduct stabilizers, and nontraditional stabilizers. Examples of traditional stabilizers are hydrated lime, Portland cement, and fly ash. Examples of byproduct stabilizers are cement kiln dust, lime kiln dust, and other forms of byproduct lime. Nontraditional stabilizers are classified into five groups: electrolytes, enzymes, mineral pitches, clay fillers, and acrylic polymers. Although many researches dealt with many types of soil stabilization with different stabilizers, this research shifted the direction of soil treatment into a new stabilizer material whereby fibers and cement can be used to treat clayey sand soil. So, this research effort is presented to study the effect of different types and percentages of fibers and cement on the geotechnical properties of clayey sand soil. The aim of this research is to study the engineering properties of artificial clayey sand soil reinforced by fibers and cement.
