Furthermore, impacts of the chemical composition of the fly ash glass on the conversion of the fly ash will be presented.Schulze, S. E.Rickert, JInternational Congress on the Chemistry of CementSchulze SE, Rickert J. Influence of the chemical composition of fly ashes on their reactivity. ...
1. These three constituents in oxide form made up approximately 72 % of the total mass of the fly ash composition. Table 1 Chemical composition of fly ash (FA) and Portland Cement I 42.5 R (PC) Full size table Fig. 1 XRD analysis of fly ash sample Full size image Table 2 shows the...
Fly ashBrineChemical and mineralogical compositionCo-disposalLong-term interactionMajor and minor elementsThe co-disposal of brine and fly ash has become a common practice in South African power utilities. This study focuses on the effects of the long-term fly ash–brine interaction on the chemical...
Class F Fly ash was used as the aluminosilicate source. The fly ash was collected from a coal combustion plant in Manjung, Perak, Malaysia. The chemical composition of fly ash as analyzed using X-ray fluorescence (XRF) is tabulated inTable 1. The fly ash has total SiO2and Al2O3compositio...

In fact, the matrix composition of MSS fly ash is a significantly different from that of pure MSWI ash. Previous studies have shown that the volatilization of heavy metals is related to their matrix, physical/chemical properties and the operation conditions25,26. Therefore, before conduct- ing ...
Fly ash Use of FA has become essential for civil engineering because of its economic and environmental benefits (Ravina and Mehta, 1986, Matković, 1990). The amount of cement that FA can replace is restricted by the amount of free lime in the ash. Aside from its chemical composition, the...
Coal fly ash was obtained from the ENEL thermoelectric power plant of Cerano (Brindisi, Italy). Fly ash chemical composition (Table 1) was determined by the combined use of X-ray fluorescence (XRF) analysis (Philips spectrometer PW2400; powders fused with lithium tetraborate with 1:10 w/w ra...
Electro-filter fly ash (with particle average size of 25–55 nm) was provided by Colterm Cogeneration Power station (Timisoara, Romania). The fly ash chemical composition was characterized using SEM/EDAX analysis before the preparation of absorbent. ...
One of the effective utilization strategies for fly ash and waste sludge is to use it as a fill material to raise low lying areas. Bearing capacity and settlement are the required input for the design of foundations on such fills. To determine the bearing capacity, plate load tests were carr...
