ASTM C1707-18

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: C1707 − 11 C1707 − 18
Standard Specification for
Pozzolanic Hydraulic Lime for Structural Purposes
This standard is issued under the fixed designation C1707; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This standard covers four types of pozzolanic hydraulic lime for structural purposes which include use in mortar, scratch,
brown, and finish (stucco) coats of interior or exterior plaster.
1.1.1 PHL—Pozzolanic hydraulic lime for use in mortar, scratch, brown, and finish (stucco) coats of interior or exterior plaster.
1.1.2 PHL —PHL with a maximum 20 % binder weight of hydraulic cement.
c
1.1.3 PHL-A—Air-entrained PHL.
1.1.4 PHL -A—Air-entrained PHL .
c c
1.2 The values stated in SI units are to be regarded as standard.
1.3 This specification classifies pozzolanic hydraulic lime by minimum hydrated lime content, maximum hydraulic cement
content, and specific performance requirements.
1.4 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 safety, health, and healthenvironmental practices and determine the
applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
