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% ...
Comparison of geopolymer fly ash and ordinary Portland cement to the strength of concrete
(American Scientific Publishers, 2013-12)
The aim of this study is to evaluate the effect of various fly ash: aggregate ratios by using fly ash (FA) based geopolymer compared to ordinary Portland cement (OPC) on the compressive strength of concrete. The different ...
Mechanical properties and wear behavior of brake pads produced from palm slag
(Trans Tech Publications, 2012)
Brake pads are important safety devices in vehicles. An effort to avoid the use of asbestos in brake pads has led to the development of asbestos-free brake pads that incorporate various organic and inorganic fillers. Palm ...
Pulse sign separation technique for the received bits in wireless ultra-wideband combination approach
(Hindawi Limited, 2014)
When receiving high data rate in ultra-wideband (UWB) technology, many users have experienced multiple-user interference and intersymbol interference in the multipath reception technique. Structures have been proposed for ...
Development of tetrapolar conductivity cell for liquid measurement application
(IFSA Publishing, S. L., 2014-03)
This paper deals with the development of a liquid measuring instrumentation using the popular tetrapolar electrode configuration. The system consists of four-electrode ring shape using Cromium metal plate and a small ...
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 ...
