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 ...
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 ...
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 ...
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 ...
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) ...
Effect of palm slag filler size on the mechanical and wear properties of brake pad composites
(American Scientific Publishers, 2013-01)
Particle size of filler and other material that involved in brake pad composites are expected to be able to strongly influence the wear properties and performance. Palm slag as a filler in brake pad was investigated in ...
Microstructure studies on the effect of the alkaline activators of fly ash-based geopolymer at elevated heat treatment temperature
(Trans Tech Publications, 2013)
Fly ash-based geopolymers are new binding materials produced to replace the ordinary Portland cement (OPC) used in concrete. In this research, the effect of alkaline activators on the compressive strength and the microstructure ...
Study on radioactivity components, water quality and microstructure characteristic of volcano ash as geopolymer artificial aggregate
(SYSCOM 18, 2013-06)
The assessments of radioactivity, water qualitytesting and microstructure characteristic of volcano ash have been examined. The measurement of the 226Ra, 232Th, 40K, and 238U were carried out using radioactive concentration ...
