This paper presents the study of crushed sandstones wastes (CSW) aiming at their utilization as main materials for base layer flexible pavements with series geotechnical laboratory tests contained in American Society Testing and Materials adopted evaluations. The conducted included particle size distribution, Atterberg limits, compaction characteristics, California bearing ratio, unconsolidated...

The demand for sustainable alternative construction materials to cement in modern technology cannot be underemphasized. This paper presents a non-fired green brick with an agriculture residue namely, rice husk. Although, high plasticity brown clay deposits are widely distributed in Malaysia and rice husk is a well known agriculture residue, research works on non-fired green brick with rice husk...

The changes in physical, chemical, and mineralogical properties of topsoil after forest fires their relevancy with erosion risk have been so far studied for different geographical regions ecosystems. It is well known that the increases due to loss shear strength hydraulic fire. consistency limits are strongly related soil. Nevertheless, a few studies evaluated naturally burned soils. In additio...

Red ceramics are part of one the sectors ceramic materials that make up formation civil construction complex. In Cariri region and in rest Brazil, this segment uses clay as main source raw material, which favors appearance micro, small medium enterprises produce most products manufactured by red sector. The objective work was mineralogical technological characterization a sample from potteries ...

The study was carried out with the objectives of determining stratification, geotechnical index properties soils in part Port Harcourt city and Obio/Akpor local Government Area, Rivers state. Field Exploration laboratory studies samples were obtained from 0-20.25m deep. Subsurface soil profiles delineated followed by determination their mechanical properties, including Atterberg limits, particl...

geotechnical investigations of waste fills are rarely undertaken, and consequently the geotechnical community has little knowledge of their engineering properties. in this study, a geotechnical testing program was conducted to evaluate the engineering properties of old municipal solid waste sampled in whamyung msw landfill site, busan, korea. the conducted tests included water content, specific...

in recent years, the nanoscale zero-valent iron (nzvi) particles have been used successfully for the degradation of hydrocarboncompounds and remediation of other pollutants. nevertheless, as far as we know, there is no specific study on the improvement of thegeotechnical properties of contaminated soils with hydrocarbon compounds by nzvi. this study used nzvi particles to remove gasoil in a cla...

This paper presents the results of laboratory evaluation black cotton soil stabilized with Palm Oil Fuel Ash(POFA) and Xanthan Gum(XG), to determine its suitability as reliable construction material. POFA, a major byproduct palm oil industry is being dumped into open fields which can cause environmental problems. Using POFA an additive in stabilization be eco-friendly sustainable practice. XG g...

Soil is a composition of Sand, Silt and Clay. From three phase concept, it clear that the soil consists solids, water air. The ratio weight to solids for given mass known as content soil. In other words, (w) also natural or moisture content. Water used in wide range scientific technical areas, expressed ratio, which can from zero value porosity at saturation. Traditionally, measured by pycnomet...
