These extenders decrease the cement's cost and slow down the setting times. Typically, this would affect the standardized compressive strength, bringing it down to 32.5MPa or 42.5 MPa. For block-making applications, it is best to use types of cement rated at 42.5 or 52.5 since this provides adequate strength gain.
