Comparison of dynamic mechanical properties of non-superheated and superheated A357 alloys
(Slovak Academy of Sciences, 2010-03-01)
The influence of superheat treatment on the microstructure and dynamic mechanical properties
of A357 alloys has been investigated. The study of microstructure was performed by optical
microscope. Dynamic mechanical ...
Effects of Acetic Anhydride on the properties of Polypropylene(PP)/Recycled Acrylonitrile Butadiene(NBRr)/Rice Husk Powder(RHP) composites
(Taylor and Francis Ltd., 2012-11)
PP/NBRr/RHP composites were prepared by incorporation of rice husk powder at different loadings into PP/NBRr matrix with an internal mixer at 180°C for 9 min and 50 rpm rotor speed. The effects of rice husk powder filler ...
Effect of NaOH concentration on microstructure of boiler ash based geopolymer
(Trans Tech Publications Ltd., 2015)
Boiler ash is one of the waste material from palm oil processing industry and it was widely available. The role of alkaline activator in geopolymer is important for its mechanical properties. NaOH and sodium silicate ...
Chemical and physical characterization of boiler ash from palm oil industry waste for geopolymer composite
(Syscom 18 SRL/ SC BIBLIOTECA CHIMIEI SA, 2013-12)
The characterizations of boiler ash waste from waste of palm oil industry were performed. The boiler ash was obtained from the boiler in the palm oil processing factory. The chemical and physical characterization has been ...
Properties and behavior of Geopolymer Concrete Subjected to Explosive Air Blast Loading: a review
(EDP Sciences, 2017)
The severe damage to civilian buildings, public area, jet aircraft impact and defense target under explosive blast loading can cause a huge property loss. Most of researcher discusses the topics on design the concrete ...
The Effect of Different Ratio Bottom Ash and Fly Ash Geopolymer Brick on Mechanical Properties for Non-loading Application
(EDP Sciences, 2017)
This paper studies the finding of strength and water absorption of geopolymer bricks using bottom ash and fly ash as a geopolymer raw material for non-loading application with minimum strength. The study has been conducted ...
Natural Fiber Filament Wound Composites: A Review
(EDP Sciences, 2017)
In recent development, natural fibers have attracted the interest of engineers, researchers, professionals and scientists all over the world as an alternative reinforcement for fiber reinforced polymer composites. This is ...
Chemical reactions in the geopolymerisation process using fly ash-based geopolymer: A review
(American-Eurasian Network for Scientific Information (AENSI Publisher), 2011-07)
The development of our world, demanding the power supply which is produced by combustion of coal. Unfortunately, the million of tons of fly ash and related-products have been generated. To overcome these problems, fly ash ...
The relationship of NaOH molarity, Na2SiO3/NaOH ratio, fly ash/alkaline activator ratio, and curing temperature to the strength of fly ash-based geopolymer
(Trans Tech Publications, 2011)
Geopolymer, produced by the reaction of fly ash with an alkaline activator (mixture of Na2SiO3 and NaOH solutions), is an alternative to the use of ordinary Portland cement (OPC) in the construction industry. However, there ...
Effect of Solids-To-Liquids, Na2SiO3-To-NaOH and Curing Temperature on the Palm Oil Boiler Ash (Si + Ca) Geopolymerisation System
(MDPI AG, 2015)
This paper investigates the effect of the solids-to-liquids (S/L) and Na2SiO3/NaOH ratios on the production of palm oil boiler ash (POBA) based geopolymer. Sodium silicate and sodium hydroxide (NaOH) solution were used as ...
