The research investigated the effects of particle size on mechanical, thermal and corrosion behaviour of Quarry Dust (QD) reinforced Aluminium 6063 composites. Double stir casting process was used to produce the composites with particle size of the quarry dust being A (-30+45) μm, B (-45+60) μm, C (-60+75) μm and D (-75) μm. Mechanical …

The thermal conductivity of QFAC brick was as low as that of clay bricks. Hence QFAC bricks are a superior replacement and environmentally sustainable material for clay bricks.

The high volume of refined quarry dust in ed concrete slightly increased the thermal conductivity due to the refinement of pore formation and the denser …

The blocks showed high thermal conductivity, since the air voids which are bad conductors of heat, were filled with fine quarry dust powder. Hence, from the study, it can be established that the new blocks are not suitable to be used as a …

When compared to the reference brick, it is discovered that the brick with plastic content exhibits the least strength, highest tensile strength, and lowest heat conductivity. Adiyanto et al. [ 10] added 1.65 and 2.38 kg of plastic trash along with cement, sand, and quarry dust.

Quarry dust was fixed at 75% for every variable mix and the balance of 25% sand was replaced by kenaf core at 5% intervals, respectively, until the portion of sand was zero. Based on all properties studied, it is found that the addition of kenaf core affected the thermal conductivity, density, porosity, and compressive strength value.

Thermal conductivity of Granite is 3.2 W/ (m·K). The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K. It is a measure of a substance's ability to transfer heat through a material by conduction. Note that Fourier's law applies for all matter ...

The thermal conductivity and specific heat capacity exhibited better performance for all sea shell-based specimens; however, a 15% replacement of MSA seashell-based concrete can be the optimum ...
