This research is to study the recycling of residue clams shell from Mahachai Samutsakorn Thailand. This waste was collected from canned clams industry and it can be recycled as the composition of Mon brick instead of the rice husk. The study of clams shell composition found that Calcium was main composition as 98.50%VS. The moisture and ash content was 0.88% and 58.27%TS respectively. The works methodology is using ash from clams shell incinerated at temperature 900 1000 1100 and 1200oC in 5 hours respectively instead of rice husk in Mon brick processing. The fabrication of Mon brick was in size 5x5x5 cm adding ash from clams shell intead of rice husk. The result found that increasing the temperature to incinerate clams shell ash instead density and compressive strength increased while moisture and water absorption deceased. When Mon brick was fabricated in standard size at 6x15x3.5 cm the changed material characteristics was in the same trend as previous size. Mon brick in standard size adding 100% clams shell ash instead of rice husk had density 2.63 g/cm3 moisture content was 2.86% water absorption at 1 and 24h was 17.40 and 20.16% respectively and compressive strength was 0.52 MPa. These characteristics was according to standard of Engineering Institute of Thailand. It can reduce the cost of rice husk in Mon brick factory 28800 bath/year while the waste from canned clams factory could be reduced 20.94%.

This paper present the engineering properties of asphalt (AC 60/70) modified with different ratios of crumb rubber. Then select the best properties of the binder to mix asphaltic concrete. From laboratory testing results with adding 11% crumb rubber into mixtures for the best results. The properties of asphaltic concrete can be improved by adding 11% crumb rubber. For asphaltic concrete Marshall Stability increased and flow decreased with adding crumb rubber into asphalt. Comparing to ordinary asphaltic concrete (AC 60/70) the rutting resistance was increased 18% for crumb rubber modified asphalt respectively. Moreover the fatigue resistance of crumb rubber modified asphalt improved to be 1.59 times compared to AC 60/70.

The purpose of this project is to study the mechanical and physical properties of recycled roofing materials. The pulp extracted from the UHT beverage boxes to get aluminum foil mixed with low density polyethylene. This can be used engineering and is an option to reduce the amount of UHT boxes left over to roofing sheets. In experiment 3 aluminum foil medium size and fine then hot and extruded with 68 and 10 bar compression then cut into test pieces. To test mechanical and physical properties in accordance with the test standards: Torsion Testing Tensile strength Impact resistance Heat resistance water absorption and density testing. Compare the mechanical and physical properties of the material; different sizes of aluminum foil and compressive strength. To bring the best materials to the product. From the tests it was found that the properties of recycled composite materials From the box UHT beetroot This is made of coarse aluminum foil. 18.23 MPa bending strength 10.66 MPa tensile strength 110.987 J / m2 impact resistance 52.40 Shore-D Hardness 0.62 % Water Absorption 0.70 % Thickness Swelling 1.086 g/m3 Density 0.031 m2.K/W Thermal Resistance and 0.291 W/mK Thermal Conductivity is the best mechanical properties. Due to the large aluminum foil it can be used for high strength. Which is higher than the aluminum foil of a smaller size.

WC powder was obtained from recycling cemented carbide scraps. This metal power contained tungsten carbide (WC) at 89.17% titanium (Ti) at 4.90% tantalum (Ta) at 3.56% niobium (Nb) at 1.31% and molybdenum (Mo) at 0.93%. Its particle size and distribution was in the range of 0.03-85.31 µm. After quality improvement of the metal powder by ball milling screening and separating the compounds the result showed that the particle size of the metal powder was decreased to 0.01-0.10 µm (10-100 nm). The average size of the powdered particle was 28 nm. The tungsten powder was in more perfect condition by 95.85%

This research was on the production of hardmetal from recovery of tungsten carbide tool scraps recycling through ball milling for 40 hours. The metal powder obtained which was of the size between 0.11-0.22 µm was composed of 96.69% of tungsten carbide (WC) 1.68% of tantalum (Ta) 1.21% of titanium (Ti) and 0.42% of niobium (Nb). When mixed with 5-15% cobalt binder metal cold isostatic press (CIP) sintered at 1450 ° C it became hardmetal work piece dimension 12.39 x 13.82 x 5.60 mm with 1410 HV hardness and 14.34 g/cm3 density. The result of S45C steel turning was tools life good. The research concluded that the hardmetal work piece produced by the developed material had suitable basic specification and would lead to the development in working in the future.
