The partitioning behavior of fly ash in the PEG-2000 Na{sub 2}SO{sub 4}/H{sub 2}O system was studied and the solid in each fraction was characterized by CHN analysis (carbon content), X-ray diffraction (XRD; crystal component), and inductively coupled plasma spectrophotometry (ICP; elemental composition in the ash).
The main source of fly ash is the thermal power plant and city concentrated hot boiler with pulverized coal, of which 90% is wet gray, the activity is relativel
stone, fly-ash and ground fly-ash). Nanosilica (5–50 nm) at a dosage of 1–2% of cementitious materials was used as a viscosity-modifying agent. A constant water/cement ratio (W/C) of 0.58 was used for all mixtures, and a slump flow of 780–800 mm was maintained by adjusting the dosage of an acrylic-polymer-based super-

Portland pozzolana Cement-Fly Ash Based. The Portland Pozzolana Cement is a kind of Blended Cement which is produced by either inter-grinding of OPC clinker along with gypsum and pozzolanic materials in certain proportions or grinding the OPC clinker, gypsum and Pozzolanic materials separately and thoroughly blending them in certain proportions.
GPC is a suitable for concrete that utilizes materials such as rice husk ash and fly ash in terms of sustainability . When compared to OPC, the emission of GPC is 64 % fewer carbon dioxide during its production life cycle . Moreover, depending on the use of alkaline liquids, it has the possibility to save even 30 % on costs .
The grinding process has become widely used to improve the fineness and performance of fly ash. However, most studies focus on the particle size distribution of ground fly ash, while the particle morphology is also an important factor to affect the performance of cement paste. This article aims at three different kinds of ground fly ash from the ball mill and vertical mill, and the particle ...
