“…The result from the borehole log ( Figure 4) revealed the geomaterial in the second layer to be sandy clay of firm to stiff consistency underlain by a medium dense sand material. The sand material is more geotechnically stable because it has high shear strength and low compressibility potential (Atat, et al [7], Sarsby, [22]). The formation at this depth can be considered for engineering construction purposes.…”

Abstract. The financial implications and the time required for carrying out a comprehensive geotechnical investigation to characterize a site can discourage prospective private residential building developers, especially where a large area of land is to be investigated for construction purposes. Also, most of the geotechnical test procedures utilized during site investigation only provide information on points tested in the subsurface. This research method suggests an approach of investigating the subsurface condition of a site in order to obtain key subsoil geotechnical properties necessary for foundation design for proposed engineering facilities. Seismic wave velocities generated from near surface refraction were combined with percussion drilling and cone penetration tests to obtain a comprehensive geotechnical investigation. From the results of the seismic refraction method, the bulk density of the soil, Young's modulus, bulk modulus, shear modulus and allowable bearing capacity of a competent layer that can bear structural load at the particular study site were determined. The most competent layer was found within the depth observed by geotechnical methods. In addition, regression equations were developed in order to directly obtain the bulk density of the soil, Young's modulus, bulk modulus, shear modulus and allowable bearing capacity from the primary wave velocities.

“…4 shows graphically the effect of the five factors on erosion rate. From this analysis it is concluded that factor levels A 1 , B 4 , C 4 , D 4 and E 3 are optimum levels to get minimum erosion rate. Table IV shows the ANOVA result for the erosion rate of composites under erosion wear.…”

“…Till now, construction waste, blast furnace and steel slag, coal fly ash and bottom ash, have been accepted in many places as alternative aggregates in embankment, pavement, road, foundation and building construction. Metal industry slag, mine-stone and mining waste are generally suitable for recycling or reuse, and the use of these inorganic wastes as alternative materials in building, road and geotechnical constructions [1]- [4]. Mroueh et al [5] attempted to carry out life-cycle analysis of the use of metal industry slag in road and earth constructions, and their analysis yielded promising conclusions for the reuse of this type of waste.…”

Abstract-Recently, the use of natural fiber reinforced composites starts gaining popularity in engineering applications due to the fact that this material possesses characteristics that are comparable to conventional materials. Among natural fibers, bamboo has been widely used for many such applications due to its availability and low cost. Attempts have been made in this paper to explore the potential utilization of bamboo fiber in polymer matrix composites. Due to environmental regulations, new ways of utilizing various metal industry slags are being explored in order to safeguard the environment and to provide useful ways for their utilization and disposal. Copper slag is such an industrial waste which is produced as a by-product during smelting and refining of copper. Rich in various metal oxides, it has tremendous potential to be utilized as a filler material in polymer composites. Therefore, this work is focused on the erosion wear behavior of copper slag filled short bamboo fiber reinforced epoxy composites. It further outlines a methodology based on Taguchi's experimental design approach to make a parametric analysis of erosion characteristics.

“…The improvement of the heterogeneous waste materials like coal wash in terms of geotechnical properties has been conducted in the past (Indraratna 1994;Kamon 1997;Sarsby 2000;Pusadkar and Ramaswamy, 2005). Compaction method has been found to be useful to improve the load-deformation behaviour (stiffness) of underlying of soil layers, especially loose granular materials (Kettle, 1983;Koutsoftas and Keifer, 1990; Pan and Selby, 2002; Lee and Gu, 2004).…”

In this paper, detailed laboratory investigations were conducted on coal wash produced at coal mine, Wollongong, New South Wales, Australia. Geotechnical tests were conducted to determine the particle size distribution, compaction characteristics, shear resistance and collapse potential. The compaction tests were conducted under dry and submerged condition to examine the compactability and the strength of the coal wash. The laboratory tests show that compacted coal wash has good potential as effective fill for embankments, and land reclamation. Although coal wash is compacted under submerged condition, increased level of compaction has minimal effect.
