Using Sand Data to Communicate Performance Metrics |News| Stone Crusher
95· Green Strength Green compression strength indicates the maximum compression stress the sand mixture is capable of sustaining. It is used to determine the amount of clay addition to a green sand system. Sand to metal ratio, clay content, compactibility, and additives can affect green compression strength.
