Study on Durability of Manufactured Sand Based …
An appropriate amount of stone powder improves the durability of manufactured sand concrete. When the stone powder content is 10% or more, the chloride diffusion coefficient of manufactured sand concrete is lower than that of natural sand, and its permeability is better than that of natural sand.
Mechanical and Durability Properties of Concrete …
Foundry sand (FS) is a high silica content sand material which is a by-product from the metal alloys casting industries . In foundries, superior silica sands are bonded with clay or chemicals and used for the material molding and casting process. Foundries recycle the sand as many times as possible, and when the sand is no longer recyclable, then it is disposed of; this is called foundry sand
