Effects of elevated temperatures on the thermal behavior and mechanical performance of fly ash geopolymer paste, mortar and lightweight concrete
(Elsevier, 2014-01)
This paper reports a comparative study of the influence of elevated temperature on geopolymer paste, mortars and lightweight aggregate geopolymer concrete (LWAGC) systems made by using fly ash (FA) as only source material. ...
Photoelectrical properties and the electronic structure of Tl 1-xIn1-xSnxSe2 (x = 0, 0.1, 0.2, 0.25) single crystalline alloys
(Royal Society of Chemistry, 2013-05-14)
Photoelectrical properties of Tl1-xIn1-xSn xSe2 single crystalline alloys (x = 0, 0.1, 0.2, 0.25) grown using the Bridgman-Stockbarger method were studied. The temperature dependence of electrical and photoconductivity for ...
Microstructure study on optimization of high strength fly ash based geopolymer
(Trans Tech Publications, 2012)
The compressive strength and microstructural characteristics of fly ash based geopolymer with alkaline activator solution were investigated. The sodium hydroxide and sodium silicate were mixed together to form an alkaline ...
Infant pain detection with homomorphic filter and fuzzy k-NN classifier
(Trans Tech Publications (TTP), 2014-08)
Newborn pain is a non-stationary made by babies in reaction to certain circumstances. This infant facial expression can be used to recognize physical or psychology condition of newborn. The goal of this study is to evaluate ...
NMPC-PID based control structure design for avoiding uncertainties in attitude and altitude tracking control of quad-rotor (UAV)
(IEEE Conference Publications, 2014-03)
The extensive consideration in this research article is to utilize the advantages of two most popular control techniques which are Non-Linear Model Predictive Control (NMPC) and Proportional Integral and Derivative (PID) ...
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 ...
Microstructure study on volcano ash geopolymer aggregate at different sintering temperature
(Trans Tech Publications, 2014)
Recent research shows that the by-product materials such as fly ash can be used as raw material in producing aggregates and lightweight aggregates. The usage of this material can improve the quality of the aggregates ...
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 ...
Effect on strength and hardness of clay ceramic substrate after treatment using koalin based geopolymer glaze
(Trans Tech Publications, 2014)
Geopolymerization is an alternative for ceramic industry by using clay based material such as kaolin or calcined kaolin geopolymer. Geopolymer paste is initially produced by alkaline activation of calcined kaolin with NaOH ...
