Density functional study of electronic, charge density, and chemical bonding properties of 9-methyl-3-Thiophen-2-YI-Thieno [3,2-e] [1, 2, 4] Thriazolo [4,3-c] pyrimidine-8-Carboxylic acid ethyl ester crystals
(Elsevier B. V., 2014-06)
A comprehensive theoretical density functional investigation of the electronic crystal structure, chemical bonding, and the electron charge densities of 9-Methyl-3-Thiophen-2-YI-Thieno [3, 2-e] [1, 2, 4] Thriazolo [4,3-c] ...
Compressive strength of fly ash based geopolymer / glass fiber composite via filament winding
(Trans Tech Publications, 2014)
In general, filament winding technique is used to fabricate the composite pipes using continuous fiber and matrix resin. In this study, fly ash based geopolymer resin composites reinforced by continuous glass fiber were ...
Strength of concrete based cement using recycle ceramic waste as aggregate
(Trans Tech Publications, 2013)
The main focus of this research is to study the strength of concrete with ceramic waste as coarse aggregate. The sources of ceramic waste are obtained from the industrial in Malaysia. Presently, in ceramics industries the ...
Effect of space holder and compaction pressure on the porosity of sintered copper
(Trans Tech Publications, 2013)
The effect of space-holder content on the porosity of sintered copper that was fabricated by powder metallurgy technique has been investigated. Carbamide was used as space-holder and the content selected was 10 wt. %, 20 ...
Fire resistance evaluation of lightweight geopolymer concrete system exposed to elevated temperatures of 100-800 °C
(Trans Tech Publications, 2014)
This paper reports the fire resistance property of a lightweight aggregate geopolymer concrete (LWAGC) material synthesized by the alkali-activation of locally source fly ash (FA) after exposed to elevated temperatures ...
A study of liberation and separation process of metals from printed circuit boards (PCBS) scraps
(Trans Tech Publications, 2013-12)
Since the metallic elements are covered with or encapsulated by various plastic or ceramic materials on printed circuit boards (PCBs), a pre-treatment process allowing their liberation and separation is first needed in ...
Properties of metakaolin geopolymeric binder
(American Scientific Publishers, 2013-01)
This paper investigates the physical and mechanical properties as well as the morphology study of the MK geopolymeric binder. Mixture of waterglass liquid and NaOH solution were used as the activator solution for the ...
Band structure, density of states, and crystal chemistry of ZrGa₂ and ZrGa₃ single crystals
(Elsevier, 2013-04)
Using FP-LAPW Method we have performed calculations of the band structure of the ZrGa₂ and ZrGa₃ crystals. The all-electron full potential linearized augmented plane wave method was used to solve the Kohn Sham DFT equations. ...
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; ...
Investigating the possibility of utilization of kaolin and the potential of metakaolin to produce green cement for construction purposes-A review
(INSInet Publication, 2011-09)
Geopolymers are inorganic alkali aluminosilicate gels, formed from reaction of mineral clays or aluminosilicate-bearing industrial wastes, and treated with alkali silicate solution at 40-80°C. Geopolymers have been studied ...
