Sulfuric acid attack on ordinary Portland cement and geopolymer material
(Institute for Scientific Information (ISI), 2013-09)
The resistance of ordinary Portland cement binder towards acid had been widely discussed by researchers. The deterioration effect of this binder may cost high repair expense and rehabilitation. Geopolymer material is a new ...
Microstructural analysis of geopolymer and ordinary Portland cement mortar exposed to sulfuric acid
(Revista De Materiale Plastice, 2013-09)
The vulnerability of ordinary Portland cement (OPC) concrete to acidic attack is a worrying subject regarding the future durability of this binder. On the other side of binder's technology, the new technology of cement ...
Study on physical and chemical properties of fly ash from different area in Malaysia
(Trans Tech Publications, 2013-12)
Fly ash is residue from the combustion of coal which widely available in worldwide and lead to waste management proposal. Moreover, the use of fly ash is more environmental friendly and save cost compared to OPC. Fly ash ...
Properties of fresh palm oil fuel ash based geopolymer material
(American-Eurasian Network for Scientific Information (AENSI), 2013-10)
In this paper, palm oil fuel ash (POFA) was used as the soul material to produce geopolymer binder. Sodium silicate mixed with sodium hydroxide was used as alkaline activator to activate the palm oil fuel ash. Activator ...
A study on relationship between porosity and compressive strength for geopolymer paste
(Trans Tech Publications, 2013-12)
This paper presents a study on the relationship between porosity and compressive strength for geopolymer paste. In this research, geopolymer paste was made from fly ash class F based geopolymer mixed with alkaline activator; ...
Thermal management of electronic components by using computational fluid dynamic (CFD) software, fluent™ in several material applications (epoxy, composite material & nano-silver)
(Trans Tech Publications, 2013)
This paper presents the thermal management of electronic components, microprocessor by using three dimensional numerical analysis of heat and fluid flow in computer. 3D model of microprocessors is built using GAMBIT and ...
A new invention of thermal pad using sol-gel nano-silver doped silica film in plastic leaded chip carrier (PLCC) application by using computational fluid dynamic sofrware, CFD analysis
(Trans Tech Publications, 2013)
Thermal pad is new technology in the world that been used in PLCC in order to reduce junction temperature to the minimum level in electronic components. Thermal Pad was made by using nano-silver as main material. Nano-silver ...
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 ...
