Influence of Particle Morphology of Ground Fly Ash on the

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 Ground fly ash with a median particle size of 10.5 μm, was used as raw material mixed with NaOH as an alkali activator. Results indicated that ground fly ash gave higher strength geopolymer paste compared to original fly ash. The compressive strengths at 28 days of 20.0–23.0 MPa were obtained. Aydın et al.

Frontiers Mechanical-Chemical Activation of Coal Fly Ashes:

Fly ash morphology and cured specimen microstructure were examined under a JEOL 5400 scanning electron microscope fitted with an OXFORD LINK-ISIS EDX (energy dispersive X-ray) system. EDS analyses (on spots) were done with accelerating voltage of 20 kV, working distance of 15 mm and beam current of 20 μA and acquiring for 60 s per spot analysis.This study reports the preparation of geopolymers with a mechanical performance similar to that of cement at room temperature by ground fly ash mixed with a small amount of cement. The grinding time of fly ash raw materials was 0,20,40 and 60 min, respectively. The influence of the grinding degree of the fly ash on the properties and the Influence of different grinding degrees of fly ash on

Investigation of different ways of activation of fly ash

Cement industry emits large amount of CO2. One of the ways to reduce this emission is to use cement replacements, such as fly ash, in binding mixtures. Blends containing fly ash exhibit different properties compared to typical portland cement. In the case of very high amount of fly ash used as substitute of cement, setting and hardening The optimum grinding time was 120 min identified through the particle size distribution analysis. The mean particle size decreased from 92.09 μm to 10.5 μm in which there is 89% reduction in particle size due to the grinding of fly ash particle with grinding aids. The compressive strength results show that substitutions of Ordinary PortlandSynthesis and characterization of grinding aid fly ash
