Contribution of interfacial bonding towards geopolymers properties in geopolymers reinforced fibers: a review
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-02-17)
There is a burgeoning interest in the development of geopolymers as sustainable construction materials and incombustible inorganic polymers. However, geopolymers show quasi-brittle behavior. To overcome this weakness, ...
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) ...
Hybrid mold: comparative study of rapid and hard tooling for injection molding application using Metal Epoxy Composite (MEC)
(MDPI AG, 2021-02)
The mold-making industry is currently facing several challenges, including new competitors in the market as well as the increasing demand for a low volume of precision moldings. The purpose of this research is to appraise ...
Properties of a New Insulation Material Glass Bubble in Geopolymer Concrete
(MDPI AG, 2021-02)
This paper details analytical research results into a novel geopolymer concrete embedded with glass bubble as its thermal insulating material, fly ash as its precursor material, and a combination of sodium hydroxide (NaOH) ...
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 ...
Effect of aluminium powder on kaolin-based geopolymer characteristic and removal of Cu²⁺
(MDPI AG, 2021-02)
This current work focuses on the synthesis of geopolymer-based adsorbent which uses kaolin as a source material, mixed with alkali solution consisting of 10 M NaOH and Na₂SiO₃ as well as aluminium powder as a foaming agent. ...
Optimizing of the cementitious composite matrix by addition of steel wool fibers (chopped) based on physical and mechanical analysis
(MDPI AG, 2021-02)
The demand for durable, resistant, and high-strength structural material has led to the use of fibers as reinforcing elements. This paper presents an investigation into the inclusion of chopped steel wool fibers (CSWFs) ...
Role of sintering temperature in production of nepheline ceramics-based geopolymer with addition of ultra-high molecular weight polyethylene
(MDPI AG, 2021-02)
The primary motivation of developing ceramic materials using geopolymer method is to minimize the reliance on high sintering temperatures. The ultra-high molecular weight polyethylene (UHMWPE) was added as binder and ...
The effect of thermal annealing on the microstructure and mechanical properties of Sn-0.7Cu-xZn solder joint
(MDPI AG, 2021-02)
The microstructural properties of a Pb-free solder joint significantly affect its mechanical behaviours. This paper details a systematic study of the effect of the annealing process on the microstructure and shear strength ...
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, ...
