“…When the fire temperature was raised, the density of the samples also increased. For samples sintered at 1000 °C with increasing WTS replacement from 0% to 80%, bulk densities decreased from 20.4 to 12.8 kN m 3 ⁄ . Similarly, by comparison to the control sample at 800 °C, the bulk density for C80S20, C60S40, C40S60, and C20S80 was reduced by 7.78%, 30.57%, 41.96%, and 49.22%, respectively.…”

“…Bricks from demolition can be cleaned, reused, or repurposed, making them more sustainable than using new ones. However, traditional clay brick production involves extracting significant amounts of raw materials and consuming large amounts of energy, resulting in human-induced greenhouse gas emissions and environmental degradation [2,3]. There has been growing interest in discovering sustainable and eco-friendly alternatives to conventional clay brick production to mitigate greenhouse gas emissions and reduce the carbon footprint of the construction industry [4,5].…”

The traditional production process of clay bricks involves the extraction of significant amounts of raw materials and consumes considerable energy, leading to anthropogenic greenhouse gas emissions and environmental degradation. Using environmentally friendly materials in the construction industry has become an attractive alternative for mitigating sustainability issues. One such alternative is incorporating waste materials, such as water treatment sludge (WTS), into clay brick production. This research aims to assess the viability of using WTS as a replacement for conventional clay in fired clay brick production, thereby mitigating environmental pollution. Five distinct mixtures were created, with WTS replacing clay at 0, 20, 40, 60, and 80% ratios. The mechanical properties and durability of the produced bricks were analyzed through various tests, such as Atterberg limits, optimum water content, unconfined compression, apparent porosity, compressive strength, flexural strength, density, water absorption, and efflorescence. The results demonstrated that as WTS content increased, Atterberg limits and apparent porosity increased. The bulk density, compressive strength, and bending capacity of the specimens were found to decrease as the WTS replacement ratio increased. Additionally, moderate efflorescence was observed in samples with higher sludge ratios.
