Preparation of cyciopentyi trisiianoi siisesquioxanes - modified natural rubber (CpSSQ(OH)3 - ENR-50) composite hybrid in the presence of HCI acid
(Trans Tech Publications, 2013)
A composite comprising cyclopentyl trisilanol siisesquioxanes (CpSSQ(OH)3) and 50% epoxidized natural rubber (ENR-50) was prepared at reflux temperature employed hydrochloric acid (HCl) as catalyst. HCl was found to be an ...
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 the properties of oil palm trunk fiber (OPTF) in cement composite
(Trans Tech Publications, 2013)
Properties of oil palm trunk fiber reinforced cement composite were investigated in this study. Oil palm trunk fiber was used to improve the properties of cement composite. It was found that increasing in oil palm trunk ...
The processing, characterization, and properties of fly ash based geopolymer concrete
(Advanced Study Center Co. Ltd, 2012)
In recent years, attempts to increase the utilization of fly ash as a replacement for ordinary Portland cement (OPC) in concrete have increased in significance. Geopolymer concrete does not need the presence of Portland ...
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 ...
