Effect of sodium hydroxide molarity on physical, mechanical and thermal conductivity of metakaolin geopolymers
(IOP Publishing Ltd, 2018-03)
In the present work, the effect of different sodium hydroxide (NaOH) molarity (6M, 8M, 10M, 12M and 14M) on the physical, mechanical and thermal conductivity of metakaolin geopolymers (MkGPs) was investigated. Geopolymers ...
Phase study of titanium dioxide nanoparticle prepared via sol-gel process
(IOP Publishing Ltd, 2018-03)
In this study, titanium dioxide nanoparticles have been prepared via sol-gel process using titanium tetraisopropoxide as a precursor with hydrochloric acid as a catalyst, and ethanol with deionized water as solvents. The ...
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 ...
Preparation of heat treated Titanium Dioxide (TiO₂ ) nanoparticles for water purification
(IOP Publishing Ltd, 2018-06)
Photocatalysis using the semiconductor titanium dioxide (TiO₂) has proven to be a successful technology for waste water purification. The photocatalytic treatment is an alternative method for the removal of soluble organic ...
Degradation of organic matter from stabilized leachate by using zinc sulphate as coagulant agent
(IOP Publishing Ltd, 2018-06)
Stabilized landfill leachate often contains higher organic fractions than the young one. The organics require several sequential treatments to render the leachate parameters concentrations to permissible discharge limits ...
Characteristics of thermoplastic potato starch/bentonite nanocomposite film
(IOP Publishing Ltd, 2018-06)
The aim of this study is to investigate the effect of bentonite towards thermoplastic potato starch nanocomposite films on the mechanical, microstructure and physical properties. The nanocomposite films were prepared using ...
The influence of pre-heated treatment to improve adhesion bond coating strength of fly ash based geopolymer ceramic
(IOP Publishing Ltd, 2018-06)
The study focus on effect of pre-heated ceramic surface on the adhesion bond strength between geopolymer coating coating and ceramic substrates. Ceramic substrates was pre-heated at different temperature (400 °C, 600 °C, ...
Influence of kaolin in fly ash based geopolymer concrete: destructive and non-destructive testing
(IOP Publishing Ltd, 2018-06)
Development of geopolymer concrete is mainly to reduce the production of ordinary Portland cement (OPC) that adverse the natural effect. Fly ash is a by-product collected from electrical generating power plant which resulted ...
Durability of fly ash based geopolymer concrete infilled with rubber crumb in seawater exposure
(IOP Publishing Ltd, 2018-06)
Geopolymer is an alternative binder to replace Ordinary Portland Cement (OPC)in construction industry. Source materials that rich in silica (Si) and alumina (Al) were activated by using alkaline solution. Production of ...
Investigation on properties and leachability of sewage sludge from wastewater treatment plant incorporated in fired clay brick
(IOP Publishing Ltd, 2018-06)
Sewage sludge is produced from wastewater treatment plant that often dumped into landfill sites, lagoons or together with municipal waste. Apart from this, the disposal of this sewage sludge becoming a problem for environment. ...
