Apr 01, 1994  Green strength is commonly used to relate to molding and handling properties of the sand. Dry strength also is used sometimes to complement the green strength data by relating to the sand's shakeout properties of the sand. As moisture increases, green strength reaches a maximum and then drops as the sand becomes overtempered.
