“…% JF/ESP had the lowest value of hardness for both TJF/ESP and UJF/ESF hybrid composite. This corroborates with the study of Ekpunobi et al [ 80 ] whose research highlight the increase in fiber improve the hardness of ceiling boards produced from waste paper. However, the values obtained at that weight fraction of reinforcements were found to be better when matched with the control sample.…”

“…The increase in impact strength observed may occur owing to the presence of fiber, which is responsible for reducing the rate at which inherent crack present in the material propagate. This upholds the findings of Ekunobi et al [ 80 ], who reported an increased impact strength of ceiling board produced from waste paper with fiber addition. Impact strength was noted to increase as curing progressed from 7-14 days, this is in agreement with the findings of [ 81 ], revealing the effect of curing on impact strength and concluded that impact strength of cementitious materials improve with increase in curing days.…”

This study evaluates the effect of treated and untreated jute fiber/eggshell particulate reinforced cement-paper matrix composites for ceiling board application. Treated jute fiber (TJF) was obtained by immersing untreated jute fiber (UJF) into 1.25 M sodium hydroxide (NaOH) solution in a shaker water bath maintained at 40 °C for 4 h. Eggshells (ESP) were pulverized and sieved to -75μm. Samples were prepared by varying the fiber volume fraction from 0.5 to 2.5 wt.% in the composites. While other constituents such as the binder (cement) and eggshell were kept constant. An hydraulic press cold compaction molder was utilized in the production of the hybrid composites in a predetermined mix ratio designed based on previous research. The samples produced were cured for 7 and 14 days, then sundried for 36 h. The physical, thermal, mechanical and wear behaviour of the produced composites were evaluated while the surface morphology of the fractured splitting tensile samples were analyzed. The result reveals that TJF/ESP hybrid composites had better performance than UJF/ESP hybrid composites in most of the tests carried out. Increase in the number of curing days was found to also enhance the properties of the composite produced in majority of the test evaluated. The 0.5 wt.% UJF/ESP gave the least performance of all the composites developed. While 2.5 wt. % TJF/ESP showed an optimum properties among the composites tested. When compared with standard, it is concluded that the hybrid composites developed can be suitable for ceiling boards and also find possible application in wall partitioning.

In this paper, we report oxidation time effect on highly porous silver oxide nanowires thin films fabricated using ultrasonic spray pyrolysis and oxygen plasma etching method. The NW’s morphological, electrical, and optical properties were investigated under different plasma etching periods and the number of deposition cycles. The increase of plasma etching and oxidation time increases the surface roughness of the Ag NWs until it fused to form a porous thin film of silver oxide. AgNWs based thin films were characterized using X-ray diffraction, scanning electron microscope, transmission electron microscope, X-ray photoemission spectroscopy, and UV–Vis spectroscopy techniques. The obtained results indicate the formation of mixed mesoporous Ag2O and AgO NW thin films. The Ag2O phase of silver oxide appears after 300 s of oxidation under the same conditions, while the optical transparency of the thin film decreases as plasma etching time increases. The sheet resistance of the final film is influenced by the oxidation time and the plasma application periodicity. Graphic abstract

“…(Amit and Ipshita, 2015). Works on ceiling board using agro-wastes include the use of rice husk (Oladele et al., 2009; Suleiman et al., 2013; Madu et al., 2018), banana fibres (Stephen et al., 2014), jatropha curcas seedcake material (Olorunmaiye and Ohijeagbon, 2015), water melon peels (Idris et al., 2011), bamboo (Chibudike et al., 2011), corn cobs and cassava stalks (Amenaghawon et al., 2016) as well as other synthetic wastes like sawdust (Idehai, 2012; Akinyemi et al., 2016; Atuanya and Obele, 2016; Isheni et al., 2017; Olufemi et al., 2012) and waste paper (Ekpunobi et al., 2015). Despite the fact that a lot of agro-wastes have been utilized in the production of ceiling board, the utilization of bread fruit seed coat for ceiling board production is not available in literature, hence it forms the knowledge gap this research aims to fill.…”

Conversion of agro wastes into potential raw materials for production has gained a lot of attention in research. This has led to the development of ceiling board using waste breadfruit seed coat and Recycled Low Density Polyethylene, as filler and binder respectively. The filler material (Breadfruit seed coat), was treated with 1 mol/dm3 of NaOH to eliminate the pigment and neutralized using 0.5 mol/dm3 Acetic Acid. After drying, the filler material was ground to a particle size of 600μm. Using Central Composite Design (CCD) tool of the Design Expert software, the experimental design was set up. From the design, thirty experimental samples were developed with the production parameters; press time, press pressure, press temperature and filler/rLDPE ratio as the independent variables. The produced samples were tested for Thermal Conductivity, Water Absorption, Thickness Swell and Density tests, which formed the responses for the Central Composite Design. The results of the experiment were analysed using the Response Surface Methodology while the validation was done using the Analysis of Variance (ANOVA). The optimal values obtained for the production parameters are 19.722% filer/rLDPE, 10minutes press time, 197.31 °C press temperature and 9.042MPa press pressure, which gave a 775.661 g/cm3 density, 0.308% Water Absorption, 0.962% Thickness Swell and 0.367W/M.K Thermal Conductivity. This result shows that agro waste breadfruit seed coat is a good filler material for the production of ceiling board.
