“…Interestingly, the bulk density is not affected significantly by the proportion of either bagasse or bagasse ash. This suggests that the reduction in the weight of the pottery product due to bagasse or bagasse ash is small, whereas the decrease in the compressive strength is large [2] .…”

The objective of this research was to study the effect of bagasse and bagasse ash on the properties of pottery products. In the experiments, we varied the composition of clay by adding 2%, 4%, 6%, and 8% by weight of bagasse or by adding 5%, 10%, 15%, and 20% by weight of bagasse ash and maintained the temperature of the furnace at 900 °C. The results indicate that the best composition is obtained by adding 10% by weight of bagasse ash, which yielded pottery products with improved strength (20.10 MPa), density (1.41 g/cm3), water absorption (13.91%), and porosity (25.73%). In comparison, the composition of clay with 4% by weight of bagasse yielded strength, density, water absorption, and porosity of 10.12 MPa, 1.53 g/cm3, 19.95%, and 30.17%, respectively.

“…Previous studies have shown that the addition of biomass such as rice husk, rice husk ash, sludge from water treatment plant, dry sewage sludge, etc. can reduce the weight of a clay pot [ 1 , 2 , 3 , 4 , 5 ]. However, clay pots made using such techniques were weaker than the conventional pots.…”

“…Rapid firing causes the bloating of the clay as the formation of the glazed outer skin prevents the loss of gases such as water vapor and carbon dioxide from the interior of the clay. Therefore, the furnace temperature was gradually increased from 300°C to the decided firing temperature (Janbuala et al, 2013;Jordan et al, 2008). When the temperature reached to desired firing temperature, bricks were kept in a furnace for 8 h and finally cooled to room temperature.…”

The paper presents an experimental investigation into the possibility of producing lightweight clay bricks by adding flakes of papyrus, locally called (Bardy). The flakes were sieved to obtain a powder with maximum particle size of 2.5 mm. The bricks were prepared with the addition of increasing amounts of flakes of papyrus (0, 10, 20, 30, and 40 mass%) to the clay slurry. Different temperatures of 650, 900, and 1050°C were embayed to fire the specimens. The thermal conductivity, water absorption, porosity, bulk density, firing shrinkage, compressive strength, and bending strength of the samples were measured. It was observed that the apparent compressive strength, bending strength, firing shrinkage, thermal conductivity, and density increased with the firing temperature increase and decreased with the papyrus flakes content increase; however, water absorption and porosity showed an opposite behavior.

“…Rice husk ash (RHA) is the major agricultural waste in Thailand. It contains approximately 90% silica, which is a highly porous structure and lightweight, with a high specific surface area [5][6][7]. Therefore, attempts to do co-modified clay with phosphate rock and rice husk ash are expected to improve the porous structure and add essential nutrients to clay pellets, which finally will be available for plant uptake.…”

Calcined clay pellets are popular planting material for those who love to grow plants in pots. The calcined clay pellets consist of clay (C), phosphate rock (PR), and rice husk ash (RHA). [(1-x)(50C–50PR)-xRHA], x(RHA) = 0, 0.25, 0.30, 0.35, 0.40, 0.45, 0.50, 0.55, 0.60, and 0.65 wt% were prepared by a conventional solid-state reaction method. The samples were made into a spherical shape with a diameter of 10 mm and fired at 600℃ to 1000℃. The effect of x contents on phase formation, microstructure, and chemical properties of [(1-x)(50C–50PR)-xRHA] was studied. X-ray diffraction revealed the typical assemblages with quartz, illite, and kaolinite in all the samples. SEM images of samples showed irregular packing and a highly porous microstructure. The addition of x(RHA) contents results in porous microstructure in all the samples. The surface area and pore volume of samples increased from 8.83 m2·g-1 to 14.71 m2·g-1 and 0.938 cm3·g-1 to 0.942 cm3·g-1, respectively, with the increase of x(RHA). The density of the samples slightly decreased from 2.45±0.06 g·cm-3 to 1.94±0.05 g·cm-3, with an increase in x(RHA) contents. The capability of calcined clay pellets to immobilize plant growth-promoting fungi was then studied. The results showed that orchid endophytes, as plant growth-promoting fungi, grow well on the calcined clay pellets saturated with potato dextrose broth (PDB). Besides, all fungi can live on calcined clay pellets and stay viable for at least 35 days after inoculation. These results suggested that the calcined clay pellets could serve as planting material that enhances plant growth (via its nutrients and growth-promoting fungi) simultaneously.
