Strength and microstructural properties of mechanically-activated kaolin geopolymers
(Trans Tech Publications, 2012-12)
Kaolin geopolymers exhibit low strength properties due to its plate-like nature which contribute to smaller surface area for geopolymerization reactions. Layered kaolin structure only allows very little, if any, substitution ...
Effect of curing profile on kaolin-based geopolymers
(Elsevier B.V., 2011)
Depending on the processing conditions, geopolymers can exhibit a wide variety of properties and characteristics. Curing profile serves as a crucial parameter in synthesis of geopolymers. In this paper, the influence of ...
Influence of solids-to-liquid and activator ratios on calcined kaolin cement powder
(Elsevier BV, 2011)
This paper summarizes the effect of activator ratio on the processing of cement powder. Geopolymer slurry was produced via alkaline activation of calcined kaolin. Once the geopolymer slurry solidified, it was crushed and ...
Comparative Study of Clinker’s Transformation at Different Temperature Zone During Cement Production
(Science Publications, 2007)
Chemical composition analysis using x-ray fluorescence is one of the important quality
analysis for examining of cement and widely used in cement industries for a long time as a tool to estimate phase composition. X-ray ...
Comparative characterization of Clinker’s microstructure at different temperature zone during cement production
(Science Publications, 2007)
Temperature is an important parameter for transformation of minerals in clinker during
cement productions. It influences the formation of alite from belite during calcinations and clinkering processes. The result of ...
The fabrication of artificial marble from dolomite (Batu Reput)
(The Mineral, Metals & Materials Society (TMS), 2006-01)
Perlis is one of the major producers of "Batu Reput" in Malaysia and majority of the deposits contain of high-purity calcium and magnesium carbonate. The composition of Batu Reput is similar with the ordinary dolomite. ...
Effects of calcination temperature and zinc-source concentration on chemical-solution synthesized ZnO nanorods
(Electrochemical Society, 2006)
In this paper, ZnO nanoparticles, in particular nanorods, were prepared by a time-saving and a cost effective chemical-solution process. Zinc acetate dehydrates, 2-propanol and diethanolamine were used as the source to ...

Effect of NaOH concentration on microstructure of boiler ash based geopolymer
(Trans Tech Publications Ltd., 2015)
Boiler ash is one of the waste material from palm oil processing industry and it was widely available. The role of alkaline activator in geopolymer is important for its mechanical properties. NaOH and sodium silicate ...
Chemical and physical characterization of boiler ash from palm oil industry waste for geopolymer composite
(Syscom 18 SRL/ SC BIBLIOTECA CHIMIEI SA, 2013-12)
The characterizations of boiler ash waste from waste of palm oil industry were performed. The boiler ash was obtained from the boiler in the palm oil processing factory. The chemical and physical characterization has been ...
