3.3 - Raw Materials for Cement Manufacture

3.3 Raw materials for cement manufacture. As it turns out, this is not the case. While it is important to have the correct proportions of calcium, silicon, aluminum, and iron, the overall chemical composition and structure of the individual raw ingredients can vary considerably. The reason for this is that at the very high temperatures in the kiln,.

Production of Precast Concrete - Sustainable Precast

The raw material waste in precast concrete production is very small. The use of new technologies such as self-consolidating concrete (SCC) can significantly reduce noise and vibration in the production process. The use of high-performance concrete (HPC) enables the design and production of more slender, reliable and more durable structures with function-optimized shapes.
