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 ...
Design and measurement-based evaluation of multi-antenna mobile terminals for LTE 3500MHz band
(EMW Publishing, 2013)
Design of multi-element antennas (MA) for small mobile terminals operating at higher frequencies remains challenging despite smaller antenna dimension and possibility of achieving electrically large separation between them. ...
Machining performance of reinforced alumina insert in end milling of AISI 1018 steel
(Trans Tech Publications, 2013-09)
The main goal of this work is to investigate the performance of zirconia toughened alumina (ZTA) and ZTA reinforced with magnesium oxide (MgO) used as cutting insert in end milling of AISI 1018 steel with hardness of 27 ...
Effect of heat treatment on Ni-P-Cg(Graphite)-SiC composite coated cast AlSi alloy
(Trans Tech Publications, 2013)
The study presents the effect of heat treatment on electroless N-P-Cg-SiC composite coated cast AlSi (ADC12) alloy. No significant changes are noted on the average surface roughness and surface morphology of the coating ...
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 ...
Feasibility of producing wood fibre-reinforced geopolymer composites (WFRGC)
(Trans Tech Publications, 2013)
Wood fibres have long been known as a fibre reinforcement for concrete. Due to its availability and low production cost, this natural fibre has been used in less developed country where conventional construction materials ...
Malaysian Foxtail grass - A potential source of natural/agro fibre for polymer composite panel
(Trans Tech Publications, 2013)
Foxtail grass, also known as 'rumput bulu' by the local people, is one of the fast growing grasses abundantly available all over Malaysia. A full grown Foxtail grass attains a height of about 0.5 - 1.5 meters. The fibres ...
