Burnt clay brick is one of the major and widely used building units in masonry construction around the globe. The manufacturing of burnt clay bricks using waste plastics can minimize the environmental overburden caused by waste plastic deposition on open landfills and would also improve the brick performance at low production cost leading to more sustainable construction. This study aims to evaluate the effect of the waste Plastic in the clay bricks. In this study, the waste plastics were collected from local garbage areas respectively. Brick specimens were manufactured at an industrial brick kiln plant using various dosages (4%, 8%, and 12% by weight). The mechanical and durability properties along with microstructure of these bricks were studied. It was observed that clay bricks incorporating waste plastics have lower compressive strength compared to clay bricks without waste plastic. Scanning Electron Microscopy (SEM) analysis confirms the porous microstructure of the brick specimens incorporating plastics, which resulted in lesser unit weight leading to lighter and more economical structures. Furthermore, resistance against efflorescence was improved in all the tested bricks incorporating plastics. Based on this study, the thermal conductivity will be decreased if the shredded plastic in the bricks is increased. The weight of the brick also decreases if the shredded plastic in the brick is increased. The water absorption ratio will also be decreased if the plastic content in the bricks are increased. Overall implication of the study is it mitigates the plastic pollutions in the society and could reduce the issues of the carbon emissions to contribute to the struggle to fight climate change. The study indicates many economic benefits such as cost saving and could create different business ideas involving the recyclable plastic based bricks production ultimately boosting the economy.

The purpose of this study is to provide Pakistani citizens with Ultra-High-Performance Concrete utilizing locally available resources. In an experimental study, steel fibres are combined with silica fume and rice husk ash when superplasticizers are present. Several different tests were done using completely different volumes and different amounts of ingredients from local supplies and steel fibres to investigate ultra-high-performance concrete. Results show that ultra-high-performance concrete can be produced using locally accessible material. There are differences in the compressive and flexural strengths of the Ultra High-Performance concrete. Every outcome is pleasing. Scanning electron microscopy and X-ray diffraction tests were also used to assess the ultra-high-performance concrete's microstructural analysis. The transition zone between fine aggregates and the cement paste is enhanced by the use of silica, according to X-ray diffraction and scanning electron microscopy test results. Dense packing is one of the main factors influencing concrete strength, and it is achieved by using a low water to-cement ratio. This observation is gained from Scanning Electron Microscopy and X-ray diffraction tests. The steel fibers in ultra-high-performance concrete inhibited the propagation of cracks in the matrix.
