Mortar by Proportion or Property Specification
Original C270 had only a strength requirement
Current C270 has choice of proportions with three different types of cementitious materials or having property requirements of strength, water retention, air content and aggregate ratios
27
Cementitious Materials
There are 3 different cementitious materials available for the proportion specifications:• Cement-Lime
• Mortar Cement
• Masonry Cement
The minimum psi for Type O to M mortars per property requirements vary from 350 to 2500.

Guide for the Selection of Masonry Mortar
Table X1.1 in the Appendix is a general guide for selection of mortar type for various masonry wall construction. Selection of mortar type should also be based on the type of masonry units to be used as well as applicable building code and engineering practice standard requirements such as allowable design stresses and lateral support.

Committee C12 on Mortars and Grouts for Unit Masonry
Standard Specification for Mortar for the Repair of Historic Masonry
ASTM C1713
Steven Talafous, PE, PresenterJohn Wathne, PE, Task Group Chair
37
Committee C12 on Mortars and Grouts for Unit Masonry
While ASTM C270 does a very good job of specifying mortars for New Masonry Construction,
Prior to the publication of C1713, there was no ASTM specification to describe mortars for Historic Masonry Construction.
38
Committee C12 on Mortars and Grouts for Unit Masonry
Modern Mortars are primarily Portland Cement and Hydrated Lime based.
Historic Mortars included many different binder types that were mostly replaced by more modern materials.
A “Restoration Revolution” has been underway in the masonry industry, that has seen the revival of nearly every historic masonry material in a modern replicated form.
39
Committee C12 on Mortars and Grouts for Unit Masonry
Educated decisions must be made by the users of these newly revived materials, who proceed on the assumption that the matching the in-situ mortars with modern replications is usually better than using incompatible materials that behave differently than the original.
While ASTM specifications describe many of the constituent materials, no ASTM specification described their combination into a mortar, until C1713.
40
Committee C12 on Mortars and Grouts for Unit Masonry
Fundamental differences that makeASTM C1713 unique from ASTM C270:
1.Includes all binder materials available other than clay‐ Any “historic” mortar constituent covered by ASTM is allowed, plus “alternate materials” that may actually include clay and gypsum, subject to pre‐qualification tests.
41
Committee C12 on Mortars and Grouts for Unit Masonry
Fundamental differences that makeASTM C1713 unique from ASTM C270:
1.Includes all binder materials other than clay.2.Different sample curing regimes and curing times for carbonating vs. hydrating binders in order to more accurately represent the different processes of the respective materials‐ Cements cure by hydration, pure “air” limes cure by carbonation, hydraulic limes cure by both.
42
Committee C12 on Mortars and Grouts for Unit Masonry
• Lime Putty (C1489)• Hydrated Lime (C207)
• Hydraulic Lime (C141, C113)
• Natural Cement (C10)• Portland Cement (C150)• Masonry Cement (C91)
• Blended Hydraulic Cements(C595, C1157)

Fundamental differences that makeASTM C1713 unique from ASTM C270:
1.Includes all binder materials other than clay.2.Different sample curing regimes and curing times for carbonating vs. hydrating binders in order to more accurately represent the different processes of the respective materials.3. Allows for wider variation in proportions than ASTM C270, including aggregate composition and binder to aggregate ratios‐ Rules have been liberalized, subject to test, in order to allow binder compositions and ratios to matched to existing mortars, which may not conform to the requirements of C270.

Fundamental differences that makeASTM C1713 unique from ASTM C270:
1.Includes all binder materials other than clay.2.Different sample curing regimes and curing times for carbonating vs. hydrating binders in order to more accurately represent the different processes of the respective materials.3. Allows for wider variation in proportions than ASTM C270, including aggregate composition and binder to aggregate ratios.4.The first mortar specification to specifically address water vapor transmission, porosity, and maximum compressive strength (rather than just minimum)‐Water Vapor Permeability and an upper limit on strength are critical to the compatibility between old and new.
