“…4b revealed that the ASSJ sample had the lowest percentage of water absorption summation of about 43.5 % compared to the other samples. This validates the description of its plasticity index at 19 % as "medium plasticity" due to the addition of AJA as an addictive to ASH sample which improved the drying strength of the AASJ clay with reduced problem of fabrication, drying and shrinkage of the manufactured brick [25,32 ] For the raw state of the burnt bricks, an increase in bulk density was noticed from 1. 03 / 3 to 1.…”

The practice of mixing Asha clay and Ajagworo clay deposit at Ngene-Agu site in the ratio of 3:1 by Awgbu women for pottery business is investigated. Physical (Atterberg limits) properties, elemental content, compressive strength, water absorption and characterization for individual and mixed clays were carried out. The result obtained shows that between 700 0 C and 1100 0 C, the compressive strength of Asha clay and Ajagworo clay derived burnt bricks did not individually meet the Nigeria specifications for structural development, while that of the mixed clay derived burnt bricks satisfied the minimum strength requirement of • / at 1000 0 C and above. The result also showed that the mixed clay derived burnt bricks has the least values for porosity of • and water absorption at varying temperatures. This has proved that the practice by Awgbu women of mixing Asha and Ajagworo in the ratio of 3:1 raised the compressive strength to • / and lowered the water absorption to a minimum value of • %. This work has shown that the Awgbu mixed clay can be used for structural development in Anambara State and Nigeria.

This study examines the influence of raw material characteristics, methods of shaping and of parameters of firing process of clay bricks, on pore-size distribution and on resistance to freeze–thaw cycles (with particular emphasis on the retention time of the specimens at the maximum achieved temperature). Pore-size distribution was measured by mercury-intrusion porosimetry, while the resistance to freeze–thaw cycles was assessed by exposing the bricks to freeze–thaw cycles (HRN B.D8.011 standard) monitoring the appearance of surface changes, decrease of compressive strength as well as the Maage factor. A correlation was set up between the Maage factor and the ratio of the compressive strength before and after freezing as a quantitative indicator of bricks resistance to frost. By using this correlation for all the examined bricks, regardless of their raw material and shaping procedure, a low coefficient of correlation (R2 = 0.26) was obtained. When processed separately, machine-made bricks had a significantly higher correlation coefficient value (R2 = 0.60) than the hand-made bricks (R2 = 0.28).

“…Many kilns also use a mixture of fuels. Although, some authors describe coal as the traditional fuel in brick firing [84,85]. In other cases, fuels are added separately and in others, they are pre-mixed.…”

Artisan Brick Kilns: State-of-the-Art and Future Trends

et al. 2020

A large part of the global brick manufacturing industry has evolved based on knowledge transmitted from generation to generation without developing a consistent scientific approach. The purpose of this article is to contribute to this approach by discussing the state-of-the-art and future trends of the design and construction of artisan brick kilns (ABK). The methodology proposed for this study is based on a systematic literature review whereby main question is: What research exists on brick kilns? Based on the results of this review, it is recommended that appropriate emerging technologies that should be incorporated to ABKs for either medium or small enterprises should be: mechanical fans, envelope thermal insulation, organic waste of uniform size as fuel, automatic control of process variables and computer simulations of phenomenological processes. This should be accompanied by technical training for the brick-makers and greater access to financing funds. The technologies reviewed throughout the paper will allow for a more thermally efficient design of kilns, which will emit less hazardous greenhouse gases and atmospheric pollutants.
