Fukushima Daiichi

AbstractThe clean-up of the Fukushima Daiichi site, after the March 2011 earthquake and tsunami, continues to generate large amounts of spent adsorbents. These adsorbents need to be disposed of permanently in a low temperature immobilisation process to avoid volatilising radioactive Cs and Sr species. To this end an immobilisation process with a maximum temperature of 600 °C was developed by sintering model waste with glass frit to form a dense Glass Composite Material (GCM) wasteform. A zeolitic model wasteform, chabazite, was sintered with a lead borosilicate glass composition at a maximum temperature of 600 °C. The sintering process was optimised with various thermal treatment steps to ensure that volatile species, aqueous or otherwise, were released before full sintering to yield a dense final wasteform. With this process dense wasteforms of up to 40 wt. % chabazite have been achieved.

Waste Loading

Incineration of scheduled waste and landfilling of the incineration residue (Bottom Slag) is extensively practised in Malaysia as a treatment method for scheduled waste. Land site disposal of Bottom Slag (BS) may lead to environmental health issues and reduces the availability of land to sustain the nations development. This research aims in producing Glass Composite Material (GCM) incorporating BS and Soda Lime Silicate (SLS) waste glass as an alternative method for land site disposal method and as an effort for recycling SLS waste glass .SLS waste glass originates from the urban waste and has been a waste stream in most of the nation whereby the necessity for recycling is in high priority.The effect of BS waste loading on the GCM is studied.Batches of powder mixture is formulated with 30 wt% to 70 wt % of BS powder and SLS waste glass powder for GCM sintering.The powder mixtures of BS and SLS waste glass is compacted by uniaxial pressing method and sintered at 800C with heating rate of 2C/min and 1 hour soaking time. Physical analysis of bulk density, apparent porosity, and water absorption is perfomed according to ASTM C-373 standard. Mechanical testing of microhardness vickers according to ASTM C1327 and Modulus of Rupture (MOR) according to ISO 10545-4 is conducted. Microstructural analysis is carried out using Scanning Electron Microscope and phase analysis by X-ray diffraction method.Phases identified are Anorthite sodian,Quartz,Hematite and Diopside from X-ray diffraction analysis. Higher BS waste loading shows weak physical and mechanical properties .GCM from batch formulation of 30 wt % BS and 70 wt% SLS waste glass has projected optimized physical and mechanical properties. It is observed this batch has projected lowest water absorption percentage of 1.17 % , lowest porosity percentage of 2.2 %, highest bulk density of 1.88 g/cm3and highest MOR of 70.57 Mpa and 5.6 GPa for Vickers Microhardness.

Adhesion refers to the ability of concrete to resist slipping of reinforcement under loading in reinforced concrete products. The term "reinforced concrete" is considered as a uniform composite material as long as there is adhesion on the contact surface between the reinforcement and the concrete. In case of disruption of the reinforcement and concrete interaction, the construction is represented by separate elements. The aim of this work is to simulate the process of glass composite and metal reinforcement adhesion with cement concrete. To solve this problem, analytical modeling was performed in the ANSYS 19.0 Workbench software package, with the help of which the nature of damage accumulation in the rebar and the distribution of stresses in the concrete mass are determined.

Twenty-five Class I-III resorptive lesions in 19 cats were restored with Charisma®, a microglass-composite material. Twenty two restorations were examined 6 and 12, and 10 were examined 24 months post-treatment. Excellent results (restoration intact, no additional resorption visible) were seen in 68% of restorations at 6 months, 36% at 12 months, and 10% at 24 months.
