The use of reinforcing high performance ceramic particulates in monolithic lead-free solder is one way to improve the service temperature and mechanical behavior of a solder joint. In this study, various compositions of ...

Carbon fibers are produced from natural sources of water hyacinth plants that have been dried, ground and sieved to three different particle sizes of 600 μm, 300 μm and less than 300 μm. Through the analysis of data obtained ...

Kaolin geopolymers were produced by the alkali-activation of kaolin with an activator solution (a mixture of NaOH and sodium silicate solutions). The NaOH solution was prepared at a concentration of 6-14 mol/L and was mixed ...

Oxide molar ratios are the main key parameter determining the performance of a kaolin geopolymers. The kaolin composition and various mixture proportions will lead to different oxide molar ratios in geopolymer system. In ...

Since decades ago, corrosion is the crucial factors for million dollars loss in construction industry. Corrosion of reinforcement bar in ordinary Portland cement (OPC) concrete is mainly due to chloride and acid attack and ...

The results of the current experimental investigation indicate the significant effect of the heating periods on the compressive strength of fly ash-based geopolymers prepared at different alkaline liquid content at both ...

Torrefaction is a thermal treatment step in a relatively low temperature range of 240-300°C, which aims to produce a higher energy biomass in terms of low heating value (LHV) and light weight properties. Biomass in wood ...

Cure characteristics and morphological studies were performed to determine the influences of TOR as a compatibilizer of styrene butadiene rubber/recycled chloroprene rubber (SBR/CRr) Blends. Both uncompatibilised and ...

Shielding concretes of different iron filling contents were assessed for their anti radiation attenuation properties. The measurements have been performed by using gamma spectrometer of NaI (Tl) detector, the sources were ...

The demand for advanced thermal management materials such as silicon carbide reinforced copper matrix (Cu-SiCp) composites is increasing due to their high thermal conductivity and low CTE properties. However, the weak ...
