Reviews on the properties of aggregates made with or without geopolymerisation method
(Scientific.Net/Trans Tech Publications, 2012-12)
Aggregates are popular for use in concrete and lightweight concrete applications. Recent research shows that the by-product materials such as fly ash can be used as raw material in producing aggregates and lightweight ...
Review on fly ash-based geopolymer concrete without Portland Cement
(Academic Journals, 2011-01)
The consumption of Ordinary Portland Cement (OPC) caused pollution to the environment due to the
emission of CO2. As such, alternative material had been introduced to replace OPC in the concrete. Fly
ash is a by-product ...
Study on Characteristics of Lightweight Aggregate Concrete Made From Foam and Ordinary Portland Cement
(EDP Sciences, 2016)
The production and characteristic of lightweight bubble aggregates (LBA) are presented in this paper. The LBA are produced by
mixing between the foam and ordinary Portland cement according to the composition which has ...
Total Nitorgen Content from Earthworm (Eisenia Foetida) Using The Kjeldahl Method
(IIUM Press, International Islamic University Malaysia, 2013)
In the fish aquaculture management, fish feed is identified as a major problem. The high cost and scarcity of fishmeal in formulated feeds have led to the use of other protein sources such as earthworms ...
The Impacts of Platinum Diffusion to the Reverse Recovery Lifetime of a High Power Diode Devices
(EDP Sciences, 2016)
The reverse recovery lifetime of a diode is one the key parameter in power electronics market. To make a diode with fast switching speed, diodes are often doped with impurities such as gold and platinum to improve its ...

geometry intended for 5850 - 7075 MHz Malaysia HAPS operating band is presented.
The structure consists of three layers, with the radiator ...
The CCSRR influences towards circular microstrip antenna
(Institute of Electrical and Electronics Engineers (IEEE), 2010-06-15)
A circular profile microstrip antenna and its related structural dimensions meant for 5850-7075 MHz Malaysia HAPS operating band are investigated here. Appearing by three layers and having layer three surface copper re-shaped ...
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 ...
Effect of Glass Reinforced Epoxy (GRE) pipe filled with Geopolymer Materials for Piping Application: Compression Properties
(EDP Sciences, 2016)
The aim of this paper is to achieve the highest compressive strength of glass reinforced epoxy pipe with the geopolymer filler content of weight percentage that were used in glass reinforced epoxy pipe. The samples were ...
Comparison of original and sintered LUSI mud from East Java, Indonesia as raw material for making a geopolymer
(American Scientific Publishers, 2013-01)
This paper presents the characterization of LUSI mud from East Java, Indonesia, as a potential raw material for making a geopolymer. Two types of LUSI mud were analyzed, i.e., original LUSI mud and LUSI mud that had been ...
