ASTM D5050-96

Standard Guide for Commercial Use of Lime Kiln Dusts and Portland Cement Kiln Dusts

SCOPE
1.1 This guide is intended to evaluate and describe lime kiln dusts and Portland cement kiln dusts for uses in commercial applications. This guide is not intended to cover uses for lime or Portland cement.
1.2 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
