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 ...
Mechanical performances of fly ash geopolymer bricks
(American Scientific Publishers, 2013-01)
Geopolymer is a new class of three-dimensionally networked amorphous to semi-crystalline alumino-silicate materials, and first developed by Professor Davidovits in 1978. Geopolymers can be synthesized by mixing alumino-silicate ...
Properties of fresh palm oil fuel ash based geopolymer material
(American-Eurasian Network for Scientific Information (AENSI), 2013-10)
In this paper, palm oil fuel ash (POFA) was used as the soul material to produce geopolymer binder. Sodium silicate mixed with sodium hydroxide was used as alkaline activator to activate the palm oil fuel ash. Activator ...
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 ...
Halal based sourced EM for turbidity reducing in wastewater treatment
(Trans Tech Publications, 2014)
Effective Microorganism (EM) technology was found as the credible solution to solve many environmental problems including wastewater issues. The EM which is in the form of EM mud ball was tested to be effectively used for ...
Lightweight fly ash-based geopolymer concrete
(Trans Tech Publications, 2013)
The experiments of this study were preformed to study the synthesis process for lightweight aggregate geopolymer concrete (LWAGC) using normal sand as a fine aggregate and expanded clay as lightweight aggregate. The LWAGC ...
Potential of upgrading domestic biomass into a higher energy density via torrefaction process
(Trans Tech Publications, 2013)
Torrefaction is a thermal treatment step in a relatively low temperature range of 240-300°C, which aims to produce a higher energy biomass in terms of low heating value (LHV) and light weight properties. Biomass in wood ...
