what is defference between fly ash and quaary dust
Effect of Fly Ash on Mortar Mixes with Quarry Dust as Fine
It was observed that the decrease in early strength by the addition of fly ash is ameliorated by the addition of quarry dust Therefore, the results of this study provide a strong recommendation for the combined use of quarry rock dust and fly ash in mortar/concrete manufacturing Quarry dust qualifies itself as suitable substitute for river sand The results of this study suggested that quarry dust (QD), silica fume (SF) and kiln ash (KA) combinations can improve the workability of SCC, more than QD, SF and KA individually KA can also have a positive influence on the mechanical properties at early ages while SF improved bond between aggregate–matrix resulting from the formation of a less porous transition zone in concrete Effect of fly ash and silica fume on compressive strength It depends on the process and the ingredients A fly ash brick with over 70% ash can achieve a compressive strength of over 120 kg/ cm 2 or 12 N if made with modern methods It will be lighter in weight and almost half in thermal conductivity HenWhat should be the ratio of stone dust, fly ash, cement

Coal Ash Basics Coal Ash (Coal Combustion Residuals, or
Coal ash, also referred to as coal combustion residuals or CCRs, is produced primarily from the burning of coal in coalfired power plants Coal ash includes a number of byproducts produced from burning coal, including: Fly Ash, a very fine, powdery material composed mostly of silica made from the burning of finely ground coal in a boiler Bottom Ash, a coarse, angular ash particle that is Fly ash chemically reacts with the byproduct calcium hydroxide released by the chemical reaction between cement and water to form additional cementitious products that improve many desirable properties of concrete All fly ashes exhibit cementitious properties to varying degrees depending on the chemical and physical properties of both the fly ash and cement Compared to What is Fly Ash?
