How to calculate cement, sand and coarse aggregate for. Void Ratio – If you fill the shuttering area with blue metal alone it has lots of voids in it which also need to be filled by the other materials such as sand & cement. Such void gap is known as void ratio compressibility which is 20% for coarse aggregate.

Learn MoreSand to Metal ratio: This ratio is nothing but weight of sand in one mold box to bunch weight. To find the root cause for sand drop and run out needs participation of every person of different department who is related to the final quality of castings.
