Study on the geopolymer concrete properties reinforced with hooked steel fiber
(IOP Publishing Ltd, 2017-06)
In this research, Class F fly ash and a mixture of alkaline activators and different amount of hooked steel fiber were used for preparing geopolymer concrete. In order to analyses the effect of hooked steel fiber on the ...
Bond strength mechanism of fly ash based geopolymer mortars: a review
(IOP Publishing Ltd, 2017-11)
Geopolymer possess many excellent properties such as high compressive and bond strength, long term durability, better acid resistance and also known as a "Sustainable Material" due to its low carbon emission and low energy ...
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 ...
Graphene geopolymer hybrid: a review on mechanical properties and piezoelectric effect
(IOP Publishing Ltd, 2019-08)
A review on graphene geopolymers hybrid is presented, focusing on the mechanical properties and piezoelectric effect. The method and way of mixing graphene with geopolymers are discussed, including form of graphene that ...
Correlation of microstructure and flexural strength of fly ash geopolymer of varying molarities
(IOP Publishing Ltd, 2019-08)
The present work studies and compares the flexural properties of fly ash geopolymer with varying molarity of sodium hydroxide (NaOH). Different molarities of NaOH solution (6M, 8M, 10M, 12M and 14M) are used to prepare the ...
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, ...
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 ...
A review of geopolymer ceramic as a potential reinforcement material in solder alloys
(IOP Publishing Ltd, 2019-12)
Nowadays, lead-free solder has been currently used in electronic packaging technology as part of soldering material. Since SnPb was detected to produce toxicity and might harm the consumers, the usage of Pb solder has been ...
Effect of different ratio of geopolymer paste based fly ash-metakaolin on compressive strength and water absorption
(IOP Publishing Ltd, 2019-12)
This paper presents the effect of different solid to solid (S/S) ratio by mixing the fly ash and metakaolin as geopolymer paste on the compressive strength and water absorption. Fly ash is a waste materials produced by ...
Performance and characterization of geopolymer concrete reinforced with short steel fiber
(IOP Publishing Ltd, 2017-06)
In the recent years, geopolymer concrete are reporting as the greener construction technology compared to conventional concrete that made up of ordinary Portland cement. Geopolymer concrete is an innovative construction ...
