Clay bricks are extensively used as building material worldwide. Natural soil deposits are in constant reduction due to the frequent use of clay to manufacture bricks. About 1600 billion bricks are produced annually by the consumption of millions of tons of natural resources. The prime focus of this study is to assess the feasibility of using a composite mixture of waste brick powder (WBP) and waste ceramic powder (WCP) as a replacement for depleting natural resource “clay” in brick manufacturing. Based upon the previous studies, the replacement levels were kept as (4 + 5)%, (8 + 10)%, and (12 + 15)% of WCP and WBP, respectively. The brick specimens were evaluated in terms of compressive strength, modulus of rupture, density, water absorption, efflorescence, apparent porosity, resistance to chemical attack and sulfate attack, and freeze-thaw resistance. The study reveals that about 27% of clay can be replaced with ceramic waste powder and waste brick powder, which can preserve a massive amount of natural clay without compromising the quality of the bricks.

In countries near the ocean, the majority of the water used for household, agricultural, and industrial purposes is attained through seawater desalination. Desalination produces highly salty water, commonly known as reject brine, which can have many drastic, negative effects on the environment. The waste results in both an environmental challenge and an opportunity for sustainable resource utilization. This research work is a literature study to investigate the feasibility and potential benefits of utilizing reject brine waste as a sustainable construction material. The results revealed that reject brine has a prodigious possibility to be used as a binder, and in place of water in concrete. The use of reject brine in cementitious composites decreases CO2 emissions and makes them economical. Also, reject brine is fruitful in the stabilization of soil by increasing the mechanical properties and enhance the strength of soil. In essence, the use of reject brine from water desalination in construction is a sustainable and environment-friendly approach.
