The effect of damp sand content on the geopolymerization reaction of fly ash-based geopolymer mortars
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)
The results of the current experimental investigation indicates the significant effect of the
natural sand content prepared in damp condition on the compressive strength of fly ash-based
geopolymer mortars prepared at ...
The potential of mixing between ordinary portland cement and fly ash to produce the lightweight aggregate
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)
In this present study, the lightweight aggregates (LWA) were produced from ordinary Portland cement (OPC) mixed with fly ash with three type of composition. The LWA is produced in granules shape with the diameter of the ...
Linear and nonlinear optical susceptibilities and the hyperpolarizability of borate LiBaB9O15 single-crystal: theory and experiment
(American Chemical Society, 2013-11)
The single-crystal borate LiBaB9O15 was synthesized by a high-temperature solution reaction and structurally determined by the single-crystal X-ray diffraction technique. It crystallizes in the noncentrosymmetric space ...
Compressive strength and crack propagation of cement composites reinforced coconut fibre
(Medwell Journals, 2012)
This study presents the compressive strength and crack propagation of cement composites reinforced coconut fibre. The development of cement composites in this research were done by substituting coconut fibre to the portion ...
Kaolin-based geopolymers with various NaOH concentrations
(Springer Verlag, 2013-03)
Kaolin geopolymers were produced by the alkali-activation of kaolin with an activator solution (a mixture of NaOH and sodium silicate solutions). The NaOH solution was prepared at a concentration of 6-14 mol/L and was mixed ...
Numerical analysis of velocity profile in a FFS microchannel
(AENSI Publisher All rights reserved, 2013-10)
Manipulation of the fluid flow behavior in microfluidic with precision technique is crucial to satisfy the needs of miniaturized systems. Velocity measurement is one of the physical phenomena plays significant role to ...
Heat dissipation analysis under natural convection condition on high power LED
(AENSI Publisher All rights reserved, 2013-10)
As the technology downscales with superior power and increased package density, the thermal effects of the high power LED are significant. Thus, the operating junction temperature of the high power light emitting diodes ...
Mechanical properties and fracture behaviour of coconut fibre-based green composites
(Foundation for Materials Science and Engineering “Serban Solacolu”, 2012)
This paper presents the influence of natural fibre content on the mechanical properties of coconut fibre based-green composites. The mixture ratio of cement:sand by weight was fixed at 1:1. Coconut fibre was used as ...
Nutritional properties of edible bird nest
(Asian Economic and Social Society, 2013-06)
Edible bird nest (EBN) is a dried glutinous secretion from the salivary glands of several different swiftlet species. It is widely consumed as a health food due to its high beneficial effects to human health and has been ...
Influence of different exchange correlation potentials on band structure and optical constant calculations of ZrGa2 and ZrGe2 single crystals
(Elsevier B.V., 2013-10)
The all-electron full potential linearized augmented plane wave method was used to solve the Kohn Sham DFT equations. We have employed different approximations for the exchange correlation potentials, namely: LDA, GGA and ...
