Class C Fly Ash. Fly ash manufactured from the flaming of lignite or sub-bituminous coal, in addition to having pozzolanic properties, also has some self-cementing properties. In the presence of water, Class C fly ash will harden & gain strength over time. Class C fly ash generally contains more than 10% lime (Cao).
This article presents the effect of adding nano-SiO2 and nano-Al2O3 on the properties of high calcium fly ash geopolymer pastes. Nano-particles were added to fly ash at the dosages of 0%, 1%, 2%, and 3% by weight. The sodium hydroxide concentration of 10 molars, sodium silicate to sodium hydroxide weight ratio of 2.0, the alkaline liquid/binder ...

1. Introduction. From the point of innovation and application, innovative composite materials are becoming increasingly important. A structural composite is made up of two or more parts (or phases), such as fiber and matrix, that have differing macroscopic and microscopic physical/chemical properties.
The present study focuses on the advancement of novel electrode materials for supercapacitors by dispersing SiO2 nanomatrix engendered from coal fly ash (Tuticorin Thermal Power Plant) encrusting with spinel metal ferrites (NiFe2O4 (1:1)) to form SiO2-NiFe2O4 nanocomposites with excellent electrochemical performance. Changes in the …
