Step-2: Calculate the weights of materials Required in 1 Cum Concrete. Density of Cement (loose) = 1440 kgs/cum. So weight of cement required = 1440 X 0.22 = 316.2 Kgs or 6.32 bags. Density of Sand = 1600 Kgs/cum. Weight of …
Stage of Cement Manufacture. There are six main stages of cement manufacturing process. Stage 1 Raw Material Extraction/Quarry. The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale and bauxite. The ore rocks are quarried and crushed to smaller pieces of about 6 inches.
