Let's move on to Section 2, Handling,
Sampling and Construction of Masonry.
Material and storage handling is
covered under TMS 602-16.
This covers the damage and
containment of materials.
Materials must be stored off ground
and protected from the elements.
Masonry units may not be wetted unless
approved, and rebar must be free from
loose rust and other coatings 
prior to placement. 
This picture indicates the material
handling and storage of blocks.
As you see the blocks are
maintained dry and off the ground.
The proper material handling of
mortar is shown in this picture.
As you can see the mortar is delivered in
a plastic container to keep it from the
elements and it is stored off the ground
free of water and moisture. 
The special inspection requirements 
are the same.

The masonry inspector must be approved by DSA
and you can check the masonry inspectors
current certification by checking the
DSA certified masonry checklist.
Masonry special inspection
has not changed drastically.
It covers Level 3 quality assurance.
Level 3 is for buildings and structures,
and Level 2 is for veneer inspections.
Per TMS 402-16 and TMS 602-16
DSA IR 21-1
now clarifies requirements for DSA tests
and inspection for non-structural walls.
You can check this under the DSA
approved CDs or from the DSA-103
testing and inspection requirements.
Also covered under the material 
sampling and testing is that of the
block, the mortar and the grout,
which is based on f'm.
This is covered under the unit strength
method of TMS 602-16.
It should be in compliance with
f'm of 2000 PSI and based on
compressive test results for the masonry
units, mortar and grout, and should be
specified on the plans and specifications.
The second type of testing for block, mortar
and grout is when f'm
is specified greater than 2000 PSI,
this is covered in TMS 602-16.
The prism, mortar and grout shall be
tested prior to construction,
and prism tests and core tests should
be taken during construction.
There should be three tests for
every 5,000 square foot of wall
area constructed. 
Materialtesting of the masonry 
units themselves are covered 
in three references: the TMS 602-16
Article 2.3 is for CMU,
the TMS 504-16 is for
architectural cast
stone, and the ASTM C1670
is for adhered manufactured
stone masonry veneers.
Also the masonry units must be tested per
ASTM C90 for load bearing CMU. 
The required tests need to be
specified on the plans.
Normally one or two specimens are taken
from each lot and tested to meet the
2000 PSI requirements. 
Also covered in the material sampling
and testing is that of mortar, 
which is covered under
TMS 402-16 for Type S mortar
for exterior glass unit masonry.
And CBC 2103A.4 covers the
metal reinforcing and accessories,
which is also covered in
DSA IR 17-10.
Also new this year is that testing is
not required on identified rebar per
TMS 602-16. For unidentified rebar
a minimum of three tensile tests
and three bend tests are required
for each shipment and each grade,
this is covered in Section 1910A.2
of the CBC, and also DSA IR 17-10.
There has been a change in the maximum
height for low-lift construction.
The old requirement was 4'0" max.
per pour.
There is an exception for blocks
that are 10 inch and larger, that
a single pour can now be
5'4" in height.
Also is a clarification of masonry
core testing, that you only need one
core test for non-structural walls
with maximum height of 12'0"
above the top of foundation.
The compressive strength of the masonry
is specified in the CBC 2105A.2 and
this should be required on
the plans and specifications.
2000 PSI 28-day strength can use the
unit strength tests alone. For anything
greater than 2000 PSI prism tests must
be conducted prior to construction.
For existing walls you can cut a wall
out per TMS 602-16 and
the prism test performed on that.
The testing of the mortar has not changed,
the minimum strength is still
per ASTM C270 Table 1.
It should begin at the beginning of
work and tested three successive days.
Additional samples of material are
required per DSA or the Architect
or Engineer of Record. When specific
portions are specified sample and testing
during construction per ASTM C780
Annex 4 and 5 to verify compliance
with the specifications.
In addition, if the mortar is
properly specified the lab shall
prepare and test the mix. When
using the prism strength method the
mortar does not need to be tested.
Also the sampling and testing may be
exempt if they use pre-blended
mortars that conform the ASTM C270
with a valid evaluation report.
Also the mortar testing can be reduced
where non-shear walls are
less than 12 foot in height.
The material sampling of grout has
not changed. Samples of each mix must
be taken each day and for every 5,000
square foot of masonry wall area.
The minimum strength has been referenced
to a new reference TMS 602-16.
Additional samples must be taken if
the material of the grout changes,
and if you use the prism method
no grout or mortar tests are required.
What's new to the code
is that the CBC
Chapter 2105A.5 and 2105A.6, which used
to cover prisms and unit strength has
been changed to specifically
reference the TMS 602-16.
This is a change in the code
and the referencing procedure.
This is a picture of a 
test using nine blocks
so they can sample
four different grouts.
The specimens will be required to be cut
to size to be tested at a later date.
Cold weather conditions for
masonry is covered in TMS 602-16.
This is required when the temperatures
drop less than 40 degrees Fahrenheit.
Special details and requirements
shall be provided for masonry
when that temperature is reached.
Cold weather construction is broken
into four groups: less than 20 degrees,
20 to 25 degrees, 25 to 32 degrees and 32
to 40 degrees. 
For hot weather conditions 
the temperature is broken
up into two groups: when the 
air temperature is greater than 
100 degrees, or it's 90 degrees
with an eight mile an hour wind,
additional shading is required
when it's greater than 115 degrees,
or when it's 105 degrees
and the wind velocity is
greater than eight miles an hour.
The mortar must be kept less
than 120 degrees Fahrenheit.
Flush the mixer, mortar
transport, and boards to keep cool.
The mortar must be used
within a two-hour period.
Ice may be permitted to add to the
mixing water, but that ice must be
removed from the water prior to mixing.
And you must fog the masonry
three times a day for three days.
