·Low calcium fly ash ASTM Type F and the calcium aluminate cement CAC Secar 71 with an approximate amount of 70% alumina were used as raw materials The high amount of alumina in Secar 71 might promote the strength development of geopolymers To obtain a flat surface a CIVILAB core facing grinder were used for both ends of each cylinder

·As revealed in Fig 1 the silica and alumina are in form of mullite 3Al 2 O 2 aluminosilicate glass and quartz in fly of the inactive phase of mullite and glass phase in fly ash modifications were attempted to activate fly ash by way of calcination and hydration as well as some pretreatment such as grinding and leaching to make it more
·The purpose of this research is to assess the possibility of producing calcium silicate hydrates from biomass ash using techniques that include milling washing and subjecting the waste to hydrothermal treatment The effect of the water/solid ratio and milling parameters on the chemical composition of the fly ash was investigated Subsequently hydrothermal
·In this study low cost calcium based fly ash FA geopolymers were co prepared using an industrial by product calcium carbide slag CS as an alkaline activator and a wet grinding process to pre depolymerize the fly ash The effects of CS dosing and wet grinding treatment on the mechanical properties hydration and microstructure of FA
·To mitigate the cost of utilizing calcium sulfoaluminate SAC cement based grouting materials and alleviate the environmental impact of heavy metals and harmful elements in secondary aluminum ash this study investigated the effects of different secondary aluminum ash sintered ground powder AP dosages on the workability mechanical properties volume
·Moreover in furnaces oxides can interact with impurities at high temperatures forming less active compounds Electrostatic precipitators used for flue gas cleaning at thermal power plants alter the dispersion and reactivity of ash particles In high calcium fly ash free calcium oxide exists in both active and slow slaking forms
·As the raw material of geopolymer F class fly ash FFA often needs strong alkali such as NaOH to stimulate due to its low reactivity In this study FFA was refined and activated by a wet grinding process and the activation effect of calcium carbide
·Fly ash FA and calcium carbide residue CR were the major fundamental materials used in this study FA was obtained from the Mae Moh power plant in Lumpang province Thailand Recently about 70 80% of the total amounts approximately 2 million tons of fly ash have been used annually as a pozzolanic material and most of it has been
