“…A large number of refractory materials are made from naturally occurring high-melting-point oxides or compounds, like dolomite, chromite-magnesite, zirconia, aluminosilicate, carbon, and magnesia. Fireclay, a type of aluminosilicate refractory material, is one of the preferred refractory materials due to its availability (Samad et al, 2021). Clays are hydrated silico-aluminous minerals with a stacking of two different types of layers that contain silicon in tetrahedral coordination and aluminum in an octahedral environment, respectively.…”

This research studied the possibility of enhancing the refractory properties of termite-based clay with the addition of particulate snail shells. The clay was sourced from Federal University of Technology, Akure Campus while the snail shells were obtained from farmland in Akure, Ondo State. The prepared sample compositions consist of 100 wt. % clay (control sample) and those with varying proportions of 3-15 wt. % particulate snail shell. Samples produced were air dried for 48 hours. The dried samples were oven dried at a temperature of 110 °C for 2 hours and finally fired in a furnace at a temperature of 900 °C for 2 hours to increase strength for handling. The fired samples were subjected to physical and mechanical tests to determine their refractory properties. Representative samples were characterized via the stereo microscope in order to ascertain the amount and sizes of pores in the ceramic matrix composite after firing and also were characterized via ED-XRF in order to ascertain the relative abundance of the elemental constituents of the clay.Results obtained showed that termite clay admixed with 9 -12 wt. % particulate snail shells exhibited the desired properties of a good refractory material suitable for low duty work.

This study examines the ability to reduce the cost of constructing low-income housing buildings by modifying wall material properties. A new clay brick mixed with polyurethane foam was prepared. Different types of tests were conducted -compression strength, water absorption, thermal conductivity. Three types of studies were conducted literature review, experimental study to prepare samples of the different, and comparative study, to compare the construction costs using ordinary clay bricks and light bricks using the ETAB program. The test results showed that adding foam to the bricks in different proportions weakened the compressive strength of the bricks. The optimum percentage of polyurethane additive to the regular brick mixture is 30% by volume. The use of polyurethane foam bricks on building the social housing project showed a 4.15 % reduction of the total cost. It can be said that reducing the cost of the building will be higher than the calculated percentage in reducing the initial cost based on thermal conductivity tests, which will reduce the cost of the building's life cycle by reducing the cost of energy used in conditioning the building.

“…In addition, refractory materials can be categorised on the of basis chemical features such as acid, basic and neutral products. The increase in silica in a batch formulation the increase the acidity properties [3]. The amount of global of refractories consumption in the steel industry was approximately 27 million tons/year.…”

“…The vast majority of refractory are produced from geological high melting point oxides or compounds such as, alumina, carbon, magnesia, zirconia, aluminosilicate, silica, dolomite, chrome-magnesite. Among the favoured refractory material due to availability is the fireclay, which is category of aluminosilicate refractory materials [3]. Clays are hydrated silico-aluminous minerals whose structure is made up of a stacking of two types of layers containing, respectively, aluminium in an octahedral environment and silicon in tetrahedral coordination.…”

Refractories bricks’ excellent thermomechanical and chemical resistant features makes it invaluable materials in modular incinerator ˃ 1000 °C applications. In this research, suitable physicochemical and performance evaluation were employed using X-Ray Fluorescence (XRF), dimensional property assessment, linear shrinkage and water absorption analysis. The samples were sourced from Auchi (ARB1), Afowa (ARB2), Ayogwiri (ARB3), Aviele (ARB4) and Agbede (ARB5) clay minerals deposit in Edo North, Edo State, Nigeria. Then green compact samples were fired into dense phase. The result from the XRF study revealed a generally established composition of ARB1 clay mineral of SiO2: 44.34%, Al2O3: 36.36% and others. ARB2 clay mineral of SiO2: 41.78%, Al2O3: 39.62% and others. ARB3 clay mineral of SiO2: 45.04%, Al2O3: 34.01% and others. ARB4 clay mineral of SiO2: 40.12%, Al2O3: 38.96% and others. ARB5 clay mineral of SiO2: 47.03%, Al2O3: 34.52% and others. The elemental composition of ARB1-5 revealed a similar trend of alumina and silica content to high-Al2O3 bricks (SiO2: 45.0 – 56.0%, Al2O3: 39.0 – 48.0% and others) and commercial clay bricks (SiO2: 48.0%, Al2O3: 36.96% and others) respectively. An average lower percentage error ERL, ERW, and ERH of ARB1 samples 0.148, 0.248 and 0.28% were recorded respectively. The average linear shrinkage and water absorption analysis of 9.91 and 4.71% demonstrated a potential for high elasticity of modulus. The overall data from this research shows that ARB1-5 bricks can find use in incinerator and high temperature applications.
