Optimisation of Shrinkage and Strength on Thick Plate Part Using Recycled LDPE Materials
(MDPI AG, 2021-04-05)
Achieving good quality of products from plastic injection moulding processes is very challenging, since the process comprises many affecting parameters. Common defects such as warpage are hard to avoid, and the defective ...
Warpage optimisation using Recycled Polycar-bonates (PC) on Front Panel Housing
(MDPI AG, 2021-03-15)
Many studies have been done using recycled waste materials to minimise environmental problems. It is a great opportunity to explore mechanical recycling and the use of recycled and virgin blend as a material to produce new ...
Design of Experiment on Concrete Mechanical Properties Prediction: A Critical Review
(MDPI AG, 2021-04-09)
Concrete mix design and the determination of concrete performance are not merely engineering studies, but also mathematical and statistical endeavors. The study of concrete mechanical properties involves a myriad of factors, ...
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, ...
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 ...
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 ...
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 ...
Evaluation of the effect of silica fume on amorphous fly ash geopolymers exposed to elevated temperature
(MDPI AG, 2021-01)
The properties of amorphous geopolymer with silica fume addition after heat treatment was rarely reported in the geopolymer field. Geopolymer was prepared by mixing fly ash and alkali activator. The silica fume was added ...
