Abstract: Clayey and high plasticity fine grained soils usually create too much problems for earth fill works. In general, if the geotechnical properties of the existing soil are inappropriate, it is either replaced with a suitable fill material or improved on-site via various methods. This study investigated the use of lime to stabilize high-water-content high-plasticity clay for use in fill layers of an industrial region roads. Usually, drying of high-water-content clays is almost impossible at construction sites. At the beginning, MH high plasticity silt type of soil was dried first and then stabilized with hydrated lime and hydraulic lime at optimum water content and results of both lime are compared. The hydraulic lime was chosen for the real application and then, the research investigates the possibility of stabilizing high-water-content claywith a special lime called hydraulic quicklime without drying the soil. High plasticity soil was obtained from the Hadımköy district of Istanbul city

Abstract: Fly ash and bottom ash are two of the most common waste materials produced in the Philippines. Due to the potential environmental problems posed by these by-products, proper waste disposal is a major concern. Asa solution in the local setting, coal ashes were incorporated in concrete mixing as partial replacement for cement and fine aggregates. Furthermore, in efforts to produce sustainable concrete, seawater was introduced as a replacement for freshwater. This research focused on investigating the various influences of replacement materials with respect to the compressive strength development of concrete. The experiment tested the compressive strength of the modified mix containing alternative materials, with varying fly ash ratio of 0, 10, 20, 30, and 40%, respectively, and a constant 20% bottom ash replacement. The results show that fly ash replacement, curing days, and the interaction between the medium and the fly ash content significantly affect compressive strength development,
