C-Slurry is 100% Industrial Circular Material which is made from the industrial waste, based on the concepts of alkaline activated concrete. The performance of C-Slurry without cement could be compared with normal cement concrete. It has highly potential in developing sustainable building materials.

The material consists of a mixture of steel slag, lime mud, primary sludge from the wastewater treatment plant and wood dust in varying quantities, depending on the desired properties.

The innovative material is a result from one of the project-based collaboration between the university, National Cheng Kung University (NCKU), and the corporate, Chung Hwa Pulp Corporation (CHP). C-Hub NCKU as a Project holder, had integrated Techome Technology CO.,LTD., NCKU M-Arch II (Graduated Design Studio) and LiLinLab (Professional-Practiced Design Studio) into the R&D, developing CHP’s industrial waste into sustainable materials. The output increases the possibilities to transform CHP to become a zero-waste production system.

With different ingredients and proportions, C-Slurry presents a variety of colours and textures, and even in the same formula, the bricks could show different patterns at the end of effect time. The textures of the bricks is similar to artificial marble, travertine and concrete, with colours of black olive, gray and brown. The wood grain is especially a texture that is hardly seen in stone textures. Wood sawdust is added to make it similar to the texture of chipboard.
