Review of the characterization and processing of palm ash as a geopolymer composite
(American Scientific Publishers, 2013-01)
Malaysia is the world's largest producer and exporter of palm oil and it produces a million tons of palm oil waste annually. Palm ash is a by-product from the use of palm oil shells and palm oil bunches, which are used to ...
The effect of iron fillings waste contents on the attenuation level of anti-radiation shielding concrete
(Trans Tech Publications, 2013)
Shielding concretes of different iron filling contents were assessed for their anti radiation attenuation properties. The measurements have been performed by using gamma spectrometer of NaI (Tl) detector, the sources were ...
The effect of various waste materials' contents on the attenuation level of anti-radiation shielding concrete
(MDPI, Basel, Switzerland, 2013)
Samples of concrete contain various waste materials, such as iron particulates, steel balls of used ball bearings and slags from steel industry were assessed for their anti-radiation attenuation coefficient properties. The ...
Study of concrete using modified polystyrene coarse aggregate
(Trans Tech Publications, 2013)
Polymer recycling has received a great deal of attention in recent years. At the present time, small percentages of polymer wastes in Malaysia are being recycled. The recycling process has typically consisted of reprocessing ...
Influence of dolomite on the mechanical properties of boiler ash geopolymer paste
(Trans Tech Publications, 2014)
The waste material from palm oil industry has been increasing since Malaysia was the world largest exported of palm oil mill. The waste such as palm fibers, nut shells, palm kernel and empty fruit bunches are the solid ...
Reviews on the different sources materials to the geopolymer performance
(AENSI Publisher All rights reserved, 2013-10)
Geopolymer is manufactured from the aluminosilicate source material in example fly ash, silica fume, kaolin, ground granulate blast slag (GGBS), boiler ash and volcano ash reactivated via alkaline solution. But the different ...
Design, processing and characterization of fly ash-based geopolymers for lightweight concrete application
(Institute for Scientific Information (ISI), 2013-04)
The mix design of geopolymers plays important role in obtaining desirable compressive strength. Optimum mix design of geopolymers can be applied for application, such as lightweight concrete. In order to determine the ...
Characterization of LUSI mud volcano as geopolymer raw material: A review
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)
This paper summarizes the current knowledge about the potential of LUSI mud volcano, East Java, Indonesia as a raw material in geopolymer. Previous experimental study shows that the LUSI mud has a good performance when 5% ...
Mechanical properties of Sn-0.7Cu/Si 3N 4 lead-free composite solder
(Elsevier B.V., 2012-10)
The use of reinforcing high performance ceramic particulates in monolithic lead-free solder is one way to improve the service temperature and mechanical behavior of a solder joint. In this study, various compositions of ...
Study on refractory materials application using geopolymer processing
(American Scientific Publishers, 2013-01)
Geopolymer is cementitious binders that do not require the presence of ordinary Portland cement (OPC). Class F fly ash with geopolymer formulations prepared with an alkaline activator (mixture of Na2SiO3 and NaOH solutions) ...
