Study on solids-to-liquid and alkaline activator ratios on kaolin-based geopolymers
(Elsevier Ltd., 2012-10)
Kaolin and alkali activator were mixed with the solids-to-liquid ratios in range of 0.60-1.20 (Al 2O 3/Na 2O molar ratio of 0.63-1.27). Sodium silicate and sodium hydroxide ranged between 0.16 and 0.36 (SiO 2/Na 2O molar ...
Effect of mechanical activation on kaolin-based geopolymers
(Trans Tech Publications, 2012)
Raw materials kaolin was subjected to mechanical modification; the effect of the mechanical activation of kaolin on the compressive strength and morphological properties of the geopolymers has been studied. Mechanical ...
Optimization of solids-to-liquid and alkali activator ratios of calcined kaolin geopolymeric powder
(Elsevier Ltd, 2012-12)
This paper investigates the effect of S/L and alkali activator ratios on the synthesis of geopolymeric powder. Geopolymeric powder was synthesized by applying geopolymerization process. By adopting the concept of "just ...
Processing and characterization of calcined kaolin cement powder
(Elsevier Ltd, 2012-05)
Abstract
This paper aimed at investigating the possibility of calcined kaolin to produce cement powder that could be an alternative to Portland cement by applying geopolymerization process. Cement paste was firstly made ...
Influence of solidification process on calcined kaolin geopolymeric powder
(Trans Tech Publications, 2012-02)
This paper aims at investigating the influence of solidification condition on the processing of calcined kaolin geopolymeric powder. This is a new process developed using the geopolymerization process. Geopolymer slurry ...
Effect of Crumb Rubber on compressive strength of fly ash based Geopolymer concrete
(EDP Sciences, 2016)
This study explores the effect of different percentage of crumb rubber on compressive strength of fly ash based geopolymer concrete. This research attempted to produce rubberized geopolymer concrete as an environmentally ...
Kaolin Geopolymer as precursor to ceramic formation
(EDP Sciences, 2016)
This paper introduced the potential application of kaolin geopolymer as ceramic precursor. This is one of the alternatives to produce high strength ceramic at a slightly lower temperature. Upon sintering the conversion of ...
Friction and braking application of unhazardous palm slag brake pad composite
(IOP Publishing Ltd, 2018-03)
This paper reveals new alternative friction materials for brake pads. Palm slag was studied as new friction materials in brake pads but its much harder made it difficult to be applied. As a way to reduce the hardness, tire ...
Optimization of processing parameters for graphitization of oil palm trunk waste at lower heating temperature
(IOP Publishing Ltd, 2019-07)
Previously synthetic graphite was produced at higher temperature which is around 2,500°C in complex processing method. The method bear the name of the scientist whose discover the synthetic graphite namely "Acheson Process". ...
Mechanical properties and wear behavior of brake pads produced from palm slag
(Trans Tech Publications, 2012)
Brake pads are important safety devices in vehicles. An effort to avoid the use of asbestos in brake pads has led to the development of asbestos-free brake pads that incorporate various organic and inorganic fillers. Palm ...
