Fly ash porous material using geopolymerization process for high temperature exposure
(MDPI AG (Basel, Switzerland), 2012-04)
This paper presents the results of a study on the effect of temperature on geopolymers manufactured using pozzolanic materials (fly ash). In this paper, we report on our investigation of the performance of porous geopolymers ...
Effect of alkali concentration on mechanical properties of kaolin geopolymers
(Foundation for Materials Science and Engineering, 2012)
Alkali concentration is the most significant factor in geopolymerization process that must be taken into consideration during the synthesis of kaolin geopolymers. The kaolin geopolymers were prepared by mixing kaolin and ...
Effect of curing regimes on metakaolin geopolymer pastes produced from geopolymer powder
(Scientific.Net/Trans Tech Publications, 2012-12)
The properties of metakaolin geopolymer paste are affected by the alkali concentration, the initial raw materials, solidification process, and amount of mixing water as well as the curing conditions. This study aimed to ...
Potential of marine clay as raw material in geopolymer composite
(Scientific.Net/Trans Tech Publications, 2012-12)
In this research, marine clays has been studied its potential as a matrix composite materials that tend to be used as alternative materials to concrete. The study shows that marine clays which mixed with appropriate ...
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 ...
Potential application of palm ash as a raw materials in production of green glass
(Scientific.Net/Trans Tech Publications, 2012-12)
Oil Palm Ash is one of the abundance agricultural wastes found in Malaysia. This wastes need to be disposed properly. Oil palm ash contains compounds needed to produce glass. Most of raw materials (especially silica) used ...
Research development of solder materials and its intermetallic compound (IMC) study
(Scientific.Net/Trans Tech Publications, 2012-12)
Nowadays, the formation and the subsequent growth of the intermetallic compounds (IMCs) and the development of new lead-free solder systems is a major issue in soldering. The excessive growth formation of intermetallic ...
Research advances of composite solder material fabricated via powder metallurgy route
(Scientific.Net/Trans Tech Publications, 2012-12)
Researches and studies on composite solder have been done by many researchers in an effort to develop viable lead-free solders which can replace the conventional lead-based solders as lead is considered as toxic. Solder ...
The effect of curing time on the properties of fly ash-based geopolymer bricks
(Scientific.Net/Trans Tech Publications, 2012-12)
This paper reports the results of an experimental work conducted to investigate the effect of curing conditions on the properties of fly ash-based geopolymer bricks prepared by using fly ash as base material and combination ...
Application of clay - based geopolymer in brick production: a review
(Trans Tech Publications/Scientific.Net, 2012-12)
This paper reviews and summarizes the current knowledge and application of clay as a geopolymer material in production of geopolymer brick. As we understand, the nature of source materials give a significant impact to the ...
