Cementitious Materials

There are 3 different cementitious materials available for the proportion specifications:• Cement-Lime

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.

Standard Specification for Mortar for the Repair of Historic Masonry

ASTM C1713

Steven Talafous, PE, PresenterJohn Wathne, PE, Task Group Chair

37


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


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


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


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



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


• Lime Putty (C1489)• Hydrated Lime (C207)

• Hydraulic Lime (C141, C113)

• Natural Cement (C10)• Portland Cement (C150)• Masonry Cement (C91)

• Blended Hydraulic Cements(C595, C1157)

Carbonation

Binder Type: Mode of Curing:

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.

44



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.

45


Too Strong and Insufficiently Breathable a mortar has accelerated the deterioration of this 100-year old masonry pier.

Proportion or Property Specification?

Proportion Spec well-suited to:-Site Mixed Mortars -Trial Formulations

Property Spec well-suited to:- Large Projects - Pre-Blended “Bag Mix” Products

Fundamental differences that make ASTM 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).5.“Proportion Specification” and a “Property Specification” tailored to the conservation of masonry6.Many of the tested properties can also be used in evaluation of in‐situ mortars as well as substrate materials‐ This is addressed in the Appendix.

51


Use in Practice:No more “M a S o N w O r K”

- Should specify actual constituents and proportions, using the “Proportion Specification”

or- Should specify desired properties, using the

“Property Specification”

• Create Appendices- Appendix “X1” completed, working on “X2”.

• Create Annex- Would be a repository of vetted mortar test data for reference by specifiers.

66



Scope- Specification covers brick intended for use in masonry structural or facing components, or both…. manufactured from clay, shale, or similar naturally occurring earthy substances and subjected to a heat treatment …must develop a fired bond between the particulate constituents to provide the strength and durability ….

Typical use - Face bricks / Veneers

67



Two grades of brick- Severe Weathering (SW) – Moderate Weathering (MW) - - Based on weathering index

• FBA – Non uniform units , distressed , etc

68



Appendix to C 216 - is designed to explain the specification, noting subtleties and relationships that might not otherwise be clear.

Covers issues of grade and type and where to use what type of units, what causes efflorescence , etc.

69


C216 Standard Specification for Facing Brick (Solid Masonry Units Made from Clay or Shale - Efflourescence-

Is a coating, usually white, that sometimes appears on the surface of brick.

Sometimes erroneously thought to be inherent to the brick.

May come from the brick itself or from sources such as mortar, grout, adjacent materials, cleaning solutions, etc.

70



Scope- brick intended for use as paving material subjected to pedestrian and light vehicular traffic… designed for use in pedestrian applications and vehicular areas that are subjected to low volumes of vehicular traffic...must develop a fired bond between the particulate constituents to provide the strength and durability

Typical uses - Sidewalks and driveways

71



Three weathering classes

• SX – Where brick may be frozen while saturated- default

• ,MX – Exterior use but freeze thaw not an issue
