Effect on strength and hardness of clay ceramic substrate after treatment using koalin based geopolymer glaze
(Trans Tech Publications, 2014)
Geopolymerization is an alternative for ceramic industry by using clay based material such as kaolin or calcined kaolin geopolymer. Geopolymer paste is initially produced by alkaline activation of calcined kaolin with NaOH ...
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 ...
Reviews on the different sources materials to the geopolymer performance
(AENSI Publisher All rights reserved, 2013-10)
Geopolymer is manufactured from the aluminosilicate source material in example fly ash, silica fume, kaolin, ground granulate blast slag (GGBS), boiler ash and volcano ash reactivated via alkaline solution. But the different ...
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 ...
A Review on the Manufacturing of Lightweight Aggregates Using Industrial By-Product
(EDP Sciences, 2016-10)
The waste materials from industrial are one of the concern issues in sustainable development. Recycle and reduce the waste material is one of the strategies to produce the better sustainable system. One of the methods is ...
Performance of geopolymer concrete when exposed to marine environment
(IOP Publishing Ltd, 2019-07)
Over the decades, concrete is widely known as the most resourceful construction material as it is suitable for many building applications. However, despite its ability to last hundreds of years in many applications, it has ...
Behavior of alkali-activated fly ash through underwater placement
(MDPI AG, 2021-11-14)
Underwater concrete is a cohesive self-consolidated concrete used for concreting underwater structures such as bridge piers. Conventional concrete used anti-washout admixture (AWA) to form a high-viscosity underwater ...
Durability of geopolymer lightweight concrete infilled LECA in seawater exposure
(IOP Publishing Ltd, 2017-11)
This paper describes a development of lightweight concrete using lightweight expanded clay aggregate (LECA) in fly ash (FA) based geopolymer immersed in seawater. The objective of this research is to compare the performance ...
The effects of various concentrations of NaOH on the inter-particle gelation of a fly ash geopolymer aggregate
(MDPI AG, 2021-02)
Aggregates can be categorized into natural and artificial aggregates. Preserving natural resources is crucial to ensuring the constant supply of natural aggregates. In order to preserve these natural resources, the production ...
Paraffin as a phase change material in concrete for enhancing thermal energy storage
(IOP Publishing Ltd, 2020-02)
Phase change material (PCM) for thermal energy storage (TES) is the material that can absorb energy during heating process as phase change takes place and release energy to environment during cooling process. Nowadays, ...
