For this purpose, it is advisable to add local raw materials that can achieve the same performance as those presented by Silica fume. Therefore, we proceeded to the use of grinded dune sand and limestone fines coming from crushing waste (abundant materials, and therefore relatively inexpensive) as additives in the context of minimizing the cost of HPC.
