The soil has an important role in construction, namely as the loading of soil on clay. It is necessary to improve the nature of the shrinkage. The authors conducted the study to increase the strength of clay by adding wood ashes and bamboo ashes. Wood ash and bamboo ash have pozzolan properties expected to add power to clay when weighted, would drop significantly.  Material compares in this study using a mix of wood ash and bamboo ash with a variation of 0%, 4%, 8%, and 12%. Meanwhile, the clay soil is taken directly from the ravaged area, from bulging villages, from the grid district. The results showed that the soil is categorized as montmorillonite soil with properties that can damage light structures and road surface runoff. After adding wood and bamboo ash, it showed optimum results of 12% of the dry fixed test items showing a liquid limit’s value at 41,00%, plastic limit at 28,43%, and the net value of plastic limit at 12,57%. When testing for solidification using native soil at a dry volume of 7,91, gr/cm rainfall can increase by 10,42 gr/cm additives after adding 12% of wood ash and bamboo ash.Tanah memiliki peran penting dalam konstruksi yaitu sebagai pembebanan tanah pada tanah liat. Perlu untuk memperbaiki sifat penyusutan. Penulis melakukan penelitian untuk meningkatkan kekuatan tanah liat dengan cara menambahkan abu kayu dan abu bambu. Abu kayu dan abu bambu memiliki sifat pozzolan yang diharapkan dapat menambah kekuatan pada tanah liat saat tertimbang, akan turun secara signifikan. Perbandingan material dalam penelitian ini menggunakan campuran abu kayu dan abu bambu dengan variasi 0%, 4%, 8%, dan 12%. Sementara itu, tanah lempung diambil langsung dari area yang rusak, dari desa-desa yang menggembung, dari grid distrik. Hasil penelitian menunjukkan bahwa tanah tersebut dikategorikan sebagai tanah montmorillonite dengan sifat yang dapat merusak struktur ringan dan aliran permukaan jalan. Setelah dilakukan penambahan abu kayu dan bambu didapatkan hasil optimum dari 12% benda uji tetap kering yang menunjukkan nilai batas cair 41,00%, batas plastis  28,43%,   dan   nilai   bersih   batas  plastis  12,57%.   Pada pengujian solidifikasi menggunakan tanah asli pada volume kering 7,91 gr / cm curah hujan dapat meningkat sebesar 10,42 gr / cm aditif setelah penambahan 12% abu kayu dan abu bambu.

Abstract Cabot ESR HY 140 is a 5Ni-Cr-Mo-V alloy steel produced by electric-furnace melting, vacuum degassing and electroslag remelting (ESR) by use of small-heat-size technology. Electroslag refining improves cleanliness and lowers the sulfur content to provide improved isotropy, ductility and toughness. This steel is capable of developing a minimum yield strength of 140,000 psi with an optimum combination of hardenability, temperability, weldability, formability, toughness and fatigue properties. It meets many special requirements for petrochemical applications. This datasheet provides information on composition, physical properties, and elasticity as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SA-358. Producer or source: Cabot Corporation, Machinery Division.

The experimental investigation of reciprocating motion between the aluminum doped crumb rubber /epoxy composite and the steel ball has been carried out under Reciprocating Friction Tester, TR-282 to study the wear and coefficient of frictions using different normal loads (0.4Kg, 0.7Kgand1Kg), differentfrequencies (10Hz, 25Hz and 40Hz).The wear is a function of normal load, reciprocating frequency, reciprocating duration and the composition of the material. The percentage of aluminum presents in the composite changesbut the other components remain the same.The four types of composites are fabricated by compression molding process having 0%, 10%, 20% and 30% Al. The effect of different parameters such as normal load, reciprocating frequency and percentage of aluminum has been studied. It is observed that the wear and coefficient of friction is influenced by the parameters. The tendency of wear goes on decreasing with the increase of normal load and it is minimum for a composite having 10%aluminum at a normal load of 0.7Kg and then goes on increasing at higher loads for all types of composite due to the adhesive nature of the composite. The coefficient of friction goes on decreasing with increasing normal loads due to the formation of thin film as an effect of heat generation with normal load.
