A comparative analysis on the physical nature of the fly ashes, obtained from three thermal power plants, situated in West Bengal, India is presented in this work. The particle size of the fly ash samples are estimated, and their morphology and compositional analysis are made. These samples are crystalline, and the major components are mullite and quartz. Quantitative magnetic characterizations...

In hybrid alkaline fly ash cements, a new generation of binders, hydration, is characterized by features found in both ordinary portland cement (OPC) hydration and the alkali activation of fly ash (AAFA). Hybrid alkaline fly ash cements typically have a high fly ash (70 wt % to 80 wt %) and low clinker (20 wt % to 30 wt %) content. The clinker component favors curing at ambient temperature. A h...

As we know the road development is one of the major parts of growing infrastructure & Pune, which is expanding at a very fast rate, the construction of roads is of major concern. Fly Ash is one of the abundant forms of Solid Waste produced at thermal power plants. Its disposal is a big problem keeping both these concerns in mind it was tried to come out with a project which will integrate Road ...

in this study, the chemical characterization of solid residues, i.e., bottom ash, fly ash, and filter cake, produced from the izmit hazardous and Clinical waste incineration Plant (izAyDAS) was investigated. the izAyDAS is located in the city of kocaeli in turkey and it has been in use since 1997. Several parameters were measured, including AoX, Cl-, CN-, So4 2and selected heavy metals includin...

Self compacting concrete (SCC) is an innovative development of conventional concrete, which requires high binder content to increase its segregation resistance. This paper presents a comparative study on the use of different materials as binder content in SCC and their effects on the workability and strength properties are checked. Different combinations of Fly ash, Metakaolin and Saw dust ash ...

Self-compacting concrete is an innovative concrete that does not require vibration for placing and compaction. It is able to flow under its own weight, completely filling formwork and achieving full compaction even in congested reinforcement without segregation and bleeding. In the present study self compacting concrete mixes were developed using blend of fly ash and rice husk ash. Fresh proper...

<p>Fly ash, solid waste from coal-fired power plant, had been utilized as raw material for porous geopolymer by alkaline activation and addition of hydrogen peroxide (H2O2) blowing agent. Porous higher surface area total pore volume compared to fly ash without agent, namely 45.511 m2 g-1 0.05131 cc g-1, respectively. was applied adsorbent anionic dyes Eriochrome Black T (EBT) cationic Met...

present study deals with the adsorption of glycolic acid (ga) from aqueous solutions by using bagasse fly ash (bfa). bfa is a solid waste generated from bagasse fired boilers and can be used as an adsorbent. batch adsorption studies were carried out to evaluate the effect of various parameters like adsorbent dose, contact time, initial concentration and temperature on the removal of ga from aq...

rapid expansion of the industrial sector adds more effluent into the agricultural land and in the vicinity of industry, which possesses the major threat of land contamination and environmental degradation. the present study was conducted to determine toxic metal concentration in fly ash and metal accumulation potential of the saccharum munja and cynodon dactylon, the two main grass species grow...

the work focuses on the removing of cu(ii) from aqueous solution by linde f(k) zeolite. the zeolite is synthesized from fly ash by hydrothermal process. the adsorption experiments discuss several factors including the optimal solution ph, zeolite dosage, adsorption temperature, adsorption kinetics and adsorption isotherm equation. the results show that, the optimal solution ph is 6 and the effi...
