ABSTRACTThe use of steel slag has been widely used to increase soil strength. Steel slag is solid material from the process of refining molten iron in making steel which in the process uses furnace and using fuel from the air blown. The steel slag must be utilized cautiously because this material is categorized as B3 which is dangerous and toxic. The application that will be discussed in this research is “Literature Study of Mixing Clay and Sandstone with Steel Slag”. This analysis will be conducted by comparison of the data from research findings. The data used are primary and secondary. For primary data, the mixing of steel slag material is fulfilled by sandstone while this material is mixed with clay for secondary data. The experimet carried out from the data obtained are the CBR test, optimum moisture content (OMC), spesific gravity, maximum dry density, and atterberg limit. The results of data comparison; in addition of certain steel slag consist of a maximum number increase of CBR value. In addition, the growth of steel slag content can also increase spesific gravity of soil, and reduce plasticity, liquid limit and moisture content.ABSTRAKPenggunaan limbah baja telah banyak digunakan untuk peningkatan kekuatan tanah.

AbstractInvestigation into the cause of road failure has been carried out along a 60 km long Sagamu –Papalanto highway southwestern Nigeria. Geochemical, mineralogical, geotechnical and geophysical analyses were conducted to evaluate the cause of failure along the study area. The results of the laboratory tests showed that the percentage amount of fines ranges from 12 to 61.3%, natural moisture content from 6.8 to 19.7%, liquid limit in the range of 25.1–52.2%, linear shrinkage between 3.96 to 12.71%, plastic limit ranges from 18.2–35%, plasticity index ranges from 5.2 to 24.6%, free swell in the range from 5.17–43.9%, maximum dry density ranges from 1.51–1.74 g /cm3, specific gravity ranges from 2.52–2.64 and CBR between 3 and 12%. The Cone Penetrometer Test (CPT) shows a resistance value of 20–138 kgf/cm2. The major clay mineral that is predominant in the studied soil is kaolinite. The major oxides present are SiO2, Al2O3, Fe2O3, K2O, Na2O, MgO and CaO. The result of the 2D Electrical Resistivity Imaging revealed a low resistivity values for profile 2 and 3 ranging from 100 Ωm – 300 Ωm, between a distance of 20 m – 240 m along the profile to a depth of 7.60 m and a low resistivity value ranging from 50 Ωm – 111Ωm, between a distance of 80 m − 120 m along the profile to a depth of 15 m. It was concluded that the low CBR, low MDD and the class of subsoils namely A-26, A-7, A-2-7 (clayey soils) which were identified are responsible for the cause of failure experienced in the study area. These makes the soils unsuitable as road construction materials and hence, there is need for stabilization during the reconstruction and rehabilitation of the road.

Buy Back

The buy back guarantee agreement in the cooperation agreement aims to protect the bank frombusiness risks in the distribution of machine ownership financing. Buy back guarantee is defined asthe ability of the supplier as a guarantor against the bank, to "buy back" the machine object afterthe debtor is declared in default to the bank. Based on the description, the writer tries to examine theimplementation of the buy back guarantee agreement related to the distribution of machine financing,and legal remedies for the bank applying the contents of the buy back guarantee if there is default onthe debtor. The research method used in this research is normative juridical with analytical descriptivespecifications.The research was carried out through literature study, then looked at the relationshipbetween one law and another and carried out an analysis related to the application of its practice.After getting a description of the research results, the writer analyzes and draws conclusions fromthe research results obtained. Primary data collection is also carried out to support secondary data,which is obtained by documentation and bank interviews related to the machine ownership agreement.The results of the study concluded that the implementation of the buy back guarantee was carriedout in several stages, namely the stage of the debtor's statement of default, the negotiation stage,and the stage of the agreement, the application of the buy back guarantee. Apart from that, the buyback guarantee that applies to PT. BPRS XXX Bekasi, there are two types of definitions: "buy backguarantee" and "help resell" by the supplier. Legal action has never been taken by the bank whenthere is default from the debtor. The bank is more concerned about the good ethics of the supplier tobuy / help sell the machine goods. The suggestions that the writer can give include, banks must applyprudential banking principles more selectively, suppliers do not only pursue sales targets but payattention to the side of the bank so that cooperation remains well established. n addition, research isneeded regarding the perspectives of the bank, supplier and debtor in addressing the problems thatexist in buy back guarantee in more depth and breadth.

All structures built on soft soil may experience uncontrollable settlement and critical bearing capacity. This may not meet the design requirements for the geotechnical engineer. Soil stabilization is the change of these undesirable properties in order to meet the requirements. Traditional methods of stabilizing or through in-situ ground improvement such as compaction or replacement technique is usually costly. Now a safe and economic disposal of industrial wastes and development of economically feasible ground improvement techniques are the important challenges being faced by the engineering community. This work focuses on improving the soft soil brought from Baghdad by utilizing the local waste material for stabilization of soil, such as by using “Nylon carry bag’s by product” with the different percentage and corresponding to 1 %, 3% and 5% (the portion of stabilizer matters to soil net weight) of dried soil. The results indicated that as Nylon’s fiber content increases, the liquid limit decreases while the plastic limit increases, so the plasticity index decreases. Furthermore, the maximum dry density decreases while, the optimum moisture content increases as the Nylon’s fiber percentage increases. The compression index (decreases as the Nylon’s fiber increases and provides a maximum of 43% reduction by adding 5% nylon waste material. In addition, the results indicated that, the undrained shear strength increases as the nylon fiber increases.

Many pozzolans are waste products from industrial processes. Every year a huge amount of coal waste is gathered from the coal washing plant in the Hyrcanian forests of Iran. These materials can be used for soil stabilization in construction and maintenance projects of forest roads. This paper aims to (a) investigate the role of coal waste (CW) as a soil stabilizer and (b) determine the changes in soil specification regarding the environmental pollution in different combinations of materials (soil, lime (4 and 6%) and CW (3, 6, 9 and 12%)). For this purpose, different technical and environmental analysis and laboratory tests were performed. Technical tests showed that the soil liquid limit and maximum dry density decreased with an increase in lime and CW contents. Addition of CW could increase the soil CBR, UCS and OMC. According to XRD test, the addition of CW and lime can increase the size of crystals in stabilized soil samples. Environmental analysis showed that the use of stabilizer significantly reduced the concentration of heavy metals such as Cd, Cr and Pb. Also, all of the metal concentrations leached from samples satisfied the required criteria, but the addition of lime and CW increased the concentration of N, P, and K. These changes can increase the invasive species consistent with calcareous soil conditions along the roads. According to the results, the combination of coal waste and lime can be one of the best methods for in situ remediation. It would, however, be better to use a minimum amount of stabilizer in pavement layers of access roads due to environmental sensitivity.
