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 ... -
A comparative study of solder properties of Sn-0.7Cu lead-free solder fabricated via the powder metallurgy and casting methods
(Syscom 18 SRL, 2013-07)The properties of Sn-0.7Cu solder bulk prepared via the powder metallurgy (PM) method were investigated and compared with solder bulk fabricated through casting. Distinct microstructures were observed in both PM and casting ... -
Effect of curing regimes on metakaolin geopolymer pastes produced from geopolymer powder
(Scientific.Net/Trans Tech Publications, 2012-12)The properties of metakaolin geopolymer paste are affected by the alkali concentration, the initial raw materials, solidification process, and amount of mixing water as well as the curing conditions. This study aimed to ... -
General properties of kaolin geopolymers
(American Scientific Publishers, 2013-01)This paper reported the properties of kaolin geopolymers in term of the bulk density, compressive strength, qualitative observation and SEM analysis of the kaolin geopolymers. Kaolin geopolymers were synthesized through ... -
Microstructure evolution of Ag/TiO₂ thin film
(MDPI AG, 2021-01)Ag/TiO₂ thin films were prepared using the sol-gel spin coating method. The microstructural growth behaviors of the prepared Ag/TiO₂ thin films were elucidated using real-time synchrotron radiation imaging, its structure ... -
Microstructure study on optimization of high strength fly ash based geopolymer
(Trans Tech Publications, 2012)The compressive strength and microstructural characteristics of fly ash based geopolymer with alkaline activator solution were investigated. The sodium hydroxide and sodium silicate were mixed together to form an alkaline ... -
On the structure of shape memory alloys
(Trans Tech Publications, 2013-12)The paper presents the obtaining of shape memory alloys, base copper and a diffractometer and microscopic study on some samples. The study was made on CuZnAl samples, obtained by classic casting and educated. The shape ... -
Performance of Sn-3.0Ag-0.5Cu composite solder with kaolin geopolymer ceramic reinforcement on microstructure and mechanical properties under isothermal ageing
(MDPI AG, 2021-02)This paper elucidates the effect of isothermal ageing at temperature of 85 °C, 125 °C and 150 °C for 100, 500 and 1000 h on Sn-3.0Ag-0.5Cu (SAC305) lead-free solder with the addition of 1 wt% kaolin geopolymer ceramic (KGC) ... -
Properties of metakaolin geopolymeric binder
(American Scientific Publishers, 2013-01)This paper investigates the physical and mechanical properties as well as the morphology study of the MK geopolymeric binder. Mixture of waterglass liquid and NaOH solution were used as the activator solution for the ...
