bituminous emulsion insulators are types of bituminous emulsions groups composed of different grades of bitumen emulsified in water by bentonite and emulsifiers at 80-90oc. these emulsions are water resistant after drying andtheir physical and mechanical properties are superior in comparison to bitumen properties. iranian climate, because of variety and extreme variations in temperature imposes...

The use of modifiers for bituminous binders has become common practice to enhance the performances asphalt materials. As a result, binder becomes more complex, with various phase morphologies. Conventional testing methods may not always be suitable. example, European standardisation committee is looking at different ways characterise Polymer modified Bitumen. RILEM Technical Committee 272-PIM ‘...

Two different fly ash (FA) samples were tested for their ability to give synthetic zeolitic products. Polish bituminous (PB) and South African (SA) coal fly ash (FA) samples, derived from pilot-scale circulated fluidized bed (CFB) combustion facilities, have been utilized as raw materials. The two FAs underwent a hydrothermal activation with 1M NaOH solution at 90°C for 24 h. Two different FA/N...

The objective of this investigation was to evaluate pecan and almond shell-based granular activated carbon’s viability to effectively remove organic and inorganic pollutants in municipal wastewater compared to commercial carbons, Filtrasorb 200 (bituminous coal-based), and GRC-20, 206C AW (coconut shell-based). The solution to the objective was approached under three distinct phases, namely (I)...
