“…An improvement with the CBA ratio in all the formulation (ceramic ball) has been observed. The results are similar to the flexure strength obtained by [52] with sand-clay ceramic. The objective of this study being to combine sand particles together to improve it thermal properties of TESM, the tensile strength of the gotten ceramics is acceptable for all balls ceramic which ash waste, excepted N58A12C30-N and N58A12C1.30-N.…”

“…Figures 7(a)-(c) and Figures 8(a)-(c), present the results (illustrated cases) of the bulk density and axial tensile strength for each formulation respectively at 1000˚C and 1060˚C.The bulk density values range from 1730 kg/m 3 to 2050 kg/m 3 (±6%) and are similar to the one developed in the literature[52]. The overall bulk density of the pellet decreased with the increase of CBA ratio and the decrease of sand ration except the one obtained with the NS-N and C1 at 1060˚C.…”

“…The effect of CBA ratio and firing temperature is not significate on thermal conductivity. However, the minimum thermal conductivity is 0.331 W•m −1 •K −1 showing that sand and ash improve the thermal conductivity of the different ceramic balls developed and can even reach 1.014 Wm −1 •K −1 , compared to clay ceramic thermal conductivity obtained without any additive fired at 1200˚C in [52] which is around 0.3 Wm −1 •K −1 . Below 1050˚C, the clay ceramic is not properly fired, which strongly reduced its thermal conductivity as demonstrated in [58] where a value less than 0.3 Wm −1 •K −1 was measured for kaolin clay ceramic fired at 1050˚C.…”

In this paper, the mechanical and thermal properties of a sand-clay ceramic with additives coal bottom ash (CBA) waste from incinerator coal power plant are investigated to develop an alternative material for thermal energy storage (TES). Ceramic balls are developed at 1000˚C and 1060˚C using sintering or firing method. The obtained ceramics were compressed with a compression machine and thermally analyse using Decagon devise KD2 Pro thermal analyser. A muffle furnace was also used for thermal cycling at 610˚C. It was found that the CBA increased the porosity, which resulted in the increase of the axial tensile strength reaching 3.5 MPa for sand-clay and ash ceramic. The ceramic balls with the required tensile strength for TES were selected. Their volumetric heat capacity, and thermal conductivity range respectively from 2.4075 MJ•m −3 •˚C −1 to 3.426 MJ•m −3 •˚C −1 and their thermal conductivity from 0.331 Wm −1 •K −1 , to 1.014 Wm −1 •K −1 depending on sand origin, size and firing temperature. The selected formulas have good thermal stability because the most fragile specimens after 60 thermal cycles did not present any cracks. These properties allow envisioning the use of the ceramic balls developed as filler material for thermocline thermal energy storage (structured beds) in Concentrating Solar Power plants. And for other applications like solar cooker and solar dryer.

“…Waste glass are found in landfills degrading the environment, and the recycling of such waste glass as a form of reinforcement for aluminium is worth investigating. Moreso waste glass contains high content of silica as reported in our previous works [ 14 , 15 , 16 , 17 ]. This therefore motivated Adediran et al [18] to experiment on the effect of waste glass particles (average size of 23 μm) on the properties of Al 6061.…”

“…Such wastes include rice husk and its ash [11], coconut shell ash [12], eggshell [13], palm kernel shell [14] and agro fibers [15,16]. The essence of adding waste is for a low cost without compromising strength [17][18][19][20] in fact in some cases, strengths are enhanced due to initiation of pozzolanic reaction as a result of silica content present in these wastes [21][22][23].…”

Thermal efficient sandcrete bricks are masonry units with good thermal insulating properties. Wood fiber (WF) possesses low thermal conductivity, hence, its incorporation in mortar mix results in thermal efficient masonry units. Milled glass (MG) could be added for strength enhancement. This study incorporated WF into mortar mix at a constant dosage of 5 wt.%, with varying MG proportions of 0, 5, 10, 15 and 20 wt.% and cured for 7, 14 and 28 days. The results obtained showed minimization of porosity and water absorption at increasing MG content. Density and compressive strength were enhanced as MG content increased. Flexural and splitting tensile strengths appreciated and peaked at 15 wt.% MG. Thermal performance measured demonstrated progressive appreciation in thermal conductivity while specific heat capacity followed a downtrend as MG dosage increased. The study revealed that the collage of 5 wt. % wood fiber and 15 wt. % MG yielded optimum result. The study, therefore, concludes that the addition of milled glass and wood fiber positively and significantly affected the properties of sandcrete bricks. 15 wt.% of milled glass and 5% wood fiber inclusion in sandcrete bricks are recommended for use by construction practitioners.
