Characterization of Alkali Activated Materials Prepared from Continuous Attrition and Ball Milled Fly Ashes

Activated carbons from oil-fired fly ashes

Introduction. The aim of this investigation is to prepare activated carbons with good sorbent characteristics from oil-fired fly ash, looking for suitable activation processes to produce surface sites with high reactivity on the carbonaceous matrices [1-4]. In particular, the nitrogen surface sites, formed by gaseous ammonia reaction at 800°C, could greatly increase the adsorption of gaseous sp...

PROPERTIES OF ALKALI-ACTIVATED FLY ASH CONCRETE BLENDED WITH SLAG

The Preparation of Silicon and Aluminum Extracts from Tuncbilek and Orhaneli Fly Ashes by Alkali Fusion

Coal fly ash is formed as a solid waste product from the combustion of coal in coal fired power stations. Huge amounts of fly ash are produced globally every year and are predicted to increase. Nowadays, less than half of the fly ash is used as a raw material for cement manufacturing, construction and the rest of it is disposed as a waste causing yet another environmental concern. For this reas...

Synthesis and characterization of the electrospun fibers prepared from waste polymeric materials

Recently, the demands for the production of many different types of plastic wastes are greatly growing that subsequently, lead to the serious challenges in environmental considerations. Since, these materials are rarely resolved by microorganisms, hence, their recycling to the useful materials is crucial. In the present study, we used a solution electrospinning technique to synthesize nano/micr...

ALKALI Activated FLY-ASH Based Geopolymer Concrete

Considering the increasing demand for developing alternative construction materials, due to the growing environmental concerns, this paper discusses the feasibility of alkali activated geo-polymer concrete, as a future construction material. The main objective of this study involves observation of structural behaviours of the fresh fly ash-based geo-polymer concrete, understanding the basic mix...
