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 ...
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, ...
Seawater exposure effect on fly ash based geopolymer concrete with inclusion of steel fiber
(IOP Publishing Ltd, 2020-02)
Concrete is widely used in construction offshore such as concrete floating bridges and sea tank. This research is providing an alternative construction material to replace ordinary Portland cement (OPC) concrete known as ...
Characterisation at the bonding zone between fly ash based geopolymer repair materials (GRM) and ordinary portland cement concrete (OPCC)
(MDPI AG, 2020-12)
In recent years, research and development of geopolymers has gained significant interest in the fields of repairs and restoration. This paper investigates the application of a geopolymer as a repair material by implementation ...
Bonding strength characteristics of FA-based geopolymer paste as a repair material when applied on OPC substrate
(MDPI AG, 2020-05)
This investigative study aims to study the mechanical and morphological properties of fly ash (FA)-based geopolymer paste as a repair material when applied on ordinary Portland cement (OPC) overlay concrete. The first part ...
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 ...
Comparison of geopolymer fly ash and ordinary Portland cement to the strength of concrete
(American Scientific Publishers, 2013-12)
The aim of this study is to evaluate the effect of various fly ash: aggregate ratios by using fly ash (FA) based geopolymer compared to ordinary Portland cement (OPC) on the compressive strength of concrete. The different ...
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 ...
Reviews on the properties of aggregates made with or without geopolymerisation method
(Scientific.Net/Trans Tech Publications, 2012-12)
Aggregates are popular for use in concrete and lightweight concrete applications. Recent research shows that the by-product materials such as fly ash can be used as raw material in producing aggregates and lightweight ...
