The suitability of a marble sludge generated in the ornamental rock industry of Andalusia (Spain) has been assessed as raw material in ceramic bricks. Mixtures containing a clayey base and 0, 2.5, 5, 7.5, and 10wt% of marble powder have been shaped into 60 × 30 × 10-mm3 prismatic specimens and sintered at 950°C in a …

Granite powder and industrial sand have been used in concrete as alternative materials suitable for concrete production. The primary role of this paper is to use marble dust, sandstone dust, fly debris. The best answer for the marble solution issue is to use it in clusters. The use of this waste will reduce the cost of concrete; Reduction …

Rodriguez et al. [12] studied the partial replacement of raw alum sludge with cement and found a substantial drop in strength with 28-day SAIs of 30 to 50%. This was attributed to the 5.1% organic carbon content in the raw sludge sample, whereas the higher organic carbon content of 9.8% in this study led to a non-binding effect on the cement ...

The possibilities in concrete technology are developing in two main directions: green concrete (i.e. using recycled or waste raw material and decreased cement content, or limitation of raw ...
