Strength and Durability Studies of Concrete Containing Waste Foundry Sand

Recently, the availability of natural river sand has been restricted due to its high cost and scarcity. Mortar is a key component and is commonly used in the construction industry. There are numerous studies being done right now to develop substitutes for river sand, such as manufacturing sand, siliceous stone powder, crushed granite powder, etc., to relieve the demand for river sand. The main waste material created during the metal casting process is foundry sand. Recycling must be prioritised above disposal in the foundry sectors since using natural sand depletes environmental resources. In addition to discussing the cost of processing UFS and its use in M20 and M30 grade concrete, this paper compares the compressive strength of M20 and M30 grade concrete to concrete that has had UFS replaced. Therefore, using UFS rather than discarding it is a prudent decision that also reduces harm to the environment. Studies contrasting the trial mix with the control mix have been done, .
