“…Considering the lightness factor in CFA-containing brick samples, it was observed that there was a slight fluctuation differently from the samples with SFA. The rise in the lightness factor of brick samples is due to the decline in the amount of Fe 2 O 3 and organic materials (Kockal, 2012a). Thus, the increment in the lightness factor of SFA-containing brick samples was based on extreme Fe 2 O 3 content even higher than the clay as seen in table 1.…”

The use of wastes has become very significant and widespread in terms of sustainable production of clayey mixtures, since the wastes provide many advantages. In this study, the effects of two different types of fly ash, which were wastes of Seyitomer and Cayirhan thermal power plants, on the color change of brick samples with various amount of fly ash ranging between 0 to 60% at different sintering temperatures were investigated. As a result, traditional red colored bricks could be produced with fly ash without using a separate raw material to meet the color requirements. It was found that desired colors for special architectural applications could also be achieved by using fly ash.

“…All these characteristics of clay have made it among the first choice in many recent 3D printing architectural projects, along with concrete and other adobe-based materials [ 20 , 21 , 22 ]. Most of the clay building materials include illite along with quartz, feldspar, carbonates and iron oxides [ 23 , 24 , 25 , 26 ]. Preparation of illite-based ceramics is based on firing the ceramic bodies at temperatures from 700 °C to 1100 °C, which solidifies the ceramic body and enables its sufficient mechanical strength.…”

In a previously published study, the authors explained the formal design efficiency of the 3D-printed biodigital clay bricks 3DPBDCB: a project that aimed to change the conventional methods of clay brick design and mass production. This was achieved by employing the behavioural algorithms of reaction-diffusion and the shortest path that were extracted from the exact material physical properties and hydrophilic behaviours of clay and controlled material deposition 3D printing to create sustainable clay bricks. Sustainability in their use in the built environment and their production processes, with full potential sustainability aspects such as passive cooling, thermal and acoustical insulation, and bio receptivity. The current work studies the mechanical properties of the 3D-printed biodigital clay bricks as elastic and durable clay bricks whose properties depend mainly on their geometrical composition and form. Each of the three families of the 3D-printed biodigital clay bricks (V1, V2, V3) includes the linear model of a double line of 0.5 cm thickness and a bulk model of 55% density were tested for compression and elasticity and compared to models of standard industrial clay bricks. The results revealed that the best elasticity pre-cracking was achieved by the V2 linear model, followed by the V3 linear model, which also achieved the highest post-cracking elasticity—enduring until 150 kN pre-cracking and 200 kN post-cracking, which makes the V3 linear model eligible for potential application in earthquake-resistant buildings. While the same model V3-linear achieved the second-best compressive strength enduring until 170 kN. The best compressive strength was recorded by the V1 linear and bulk model enduring up to 240 kN without collapsing, exceeding the strength and resistance of the industrial clay bricks with both models, where the bulk and the perforated collapsed at 200 kN and 140 kN, respectively. Thus, the mass production and integration of the V1 bulk and linear model and the V3 linear model are recommended for the construction industry and the architectural built environment for their multi-aspect sustainability and enhanced mechanical properties.

“…At the same time, the volume coloring of the product, especially in the case of obtaining saturated color tones, requires an increased consumption of coloring additives, which increases its cost. Reducing the cost of the product in this case is possible due to the use in the compositions of the masses of man-made wastes containing in enough quantity color-forming oxides necessary to give the material the desired color [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. The choice of pigments is determined by the properties of the pigment and material, the nature of their interaction, as well as the processing parameters and operating conditions of the products.…”

The paper presents the results of investigation concerning using a high-temperature pigment based on synthetic tri-manganese tetra-oxide (Mn3O4) in the production of volume-colored bricks using red-burning clay. It is established that the introduction of a pigment in the amount of 2–4% results in a rich dark brown brick. At the same time, the intensity of the color increases with an increase in the pigment concentration from 2 to 4% and a brick firing temperature from 800 to 950°C. It has been established that with the introduction of pigment the strength of the obtained brick samples decreases, as well as the frost resistance.
