Rules for the Cement
Industry from ASTM
International
ASTM International has partnered
with the Slag Cement Association
(SCA) to develop new Product
Category Rules (PCR) for slag cement.
This PCR establishes the criteria for
developing an Environmental Product
Declaration (EPD) for slag cement
used in concrete, mortar, and other
construction applications.
“The Slag Cement Association has
long understood the potential envi-
ronmental benefit of the use of slag
cement, a recovered material,” said
John Melander, Executive Director of
SCA, and an ASTM member. “This
PCR provides a standardized method
for developing and disseminating
verifiable information about the
environmental impact of slag cement.”
EPDs are a highly regarded way to
demonstrate a company’s commitment
to sustainability, quality and responsi-
bility. Partnering with ASTM is a
convenient, credible, and cost-effective
way to develop PCRs and verify EPDs.
ASTM does not charge for the devel-
opment of a PCR.

the chemical bond fiber dosage is 20% less than the dosage
of the reference fiber, the performance of the specimen
with the chemical-bond fiber is comparable to the perfor-
mance of the specimen with the reference fiber.
Table 2 provides the percent of improvement in the
performance of the chemical-bond fiber relative to the
reference fiber for all tests. The improvement ranges from
32 to 45%, indicating that chemical modification further
enhances the already excellent performance of this
commercially available reference polypropylene fiber.

Internal testing
Internal testing at the plant helps pinpoint the causes of
variation of concrete quality and establish best practices.
Details involved in internal testing are discussed by Obla.6 For
every plant included in the request for certification, companies
should test at least two concrete mixtures at a frequency of
once per week or once every 500 yd3 (380 m3), whichever
results in the smaller number of tests. Tests conducted should
include slump, temperature, density, and/or 28-day compres-
sive strength, and air content for air-entrained concrete.
Companies should have a procedure of incorporating process
improvements based on the data analysis.

High Impact
ACI’s Concrete Terminology defines a cold joint as “a
joint or discontinuity resulting from a delay in placement of
sufficient duration to preclude intermingling and bonding
of the material, or where mortar or plaster rejoin or meet.”1
In cast-in-place concrete construction, internal vibration
is the most common method for providing adequate
consolidation of the placed concrete. In cast-in-place work,
a cold joint is formed when an initial lift of concrete
becomes too stiff for penetration by the vibrator used to
consolidate a subsequent lift. This thus precludes the
“intermingling” of material indicated in the definition.
However, ACI 309R-05 indicates that if bond is obtained
between cast sections, a cold joint is avoided.2 ACI 309R-05,
Section 7.2, states:
“When the placement consists of several layers, concrete Shotcrete cores of sections shot with up to seven layers
delivery should be scheduled so that each layer is placed
while the preceding one is still plastic to avoid cold joints.
If the underlying layer has stiffened just beyond the point
where it can be penetrated by the vibrator, bond can still be
obtained by thoroughly and systematically vibrating the
new concrete into contact with the previously placed
concrete; however, an unavoidable layer line will show on
the surface when the form is removed.”
Internal vibration is not used for consolidation of
shotcrete. Instead, thorough consolidation and densification
is provided by the high-velocity impact of fresh concrete A core taken through a shotcrete repair applied to a cast-in-place

A Metal Locator for

Contractors
Inexpensive device requires minimal training for users needing to locate

ost contractors will occasionally need to locate
reinforcing bars in a concrete structure—for
example, when they want to miss the reinforcement
when drilling holes into concrete. While there are many metal
locators on the market, many are very expensive and require
extensive training to be used successfully. Such equipment is
designed to be operated by engineers conducting a detailed
structural evaluation of an existing building.
Because contractors have only the occasional need to
find reinforcing in concrete, they need an inexpensive metal
locator that is relatively easy to use. A device to meet this
need is the MetalliScanner® m40 metal locator, developed
by the Zircon® Corporation, based in Campbell, CA.
To activate the m40 metal locator, users simply push the
power button and pass the device over the surface of the
concrete. A green light-emitting diode (LED) shows that

Infrasense GPR
Infrasense, Inc., completed subsurface investigations for 57 bridge decks in Michigan. Most of the bridge decks were
surveyed with high-speed ground-penetrating radar (GPR) and high-resolution video, and select decks were surveyed using
high-speed infrared thermography. GPR data was collected to estimate reinforcing bar depth and corrosion conditions.
The data was collected in a series of lines spaced 3 ft (1 m) transversely across the width of the deck, with each line repre-
senting a cross-sectional slice of the deck at a particular offset. Strong and uniform radar reflections indicated that the
reinforcing bars were in good condition. GPR data with weak and inconsistent reflections indicated reinforcing bar level
deterioration. As a part of the GPR data collection, high-resolution video was made to allow for subsequent mapping of
deck surface conditions. A series of infrared images were subsequently stitched together to create a full-scale plan-view
infrared map.

Advanced Composites in Bridge Construction and Repair
by Yail Jimmy Kim
Advanced composite materials for bridge structures are recognized as an alternative to conven-
tional construction materials. After an introductory overview and an assessment of the characteris-
tics of bonds between composites and quasi-brittle structures, Advanced Composites in Bridge Con-
struction and Repair discusses the use of advanced composites in the design and construction of
bridges, including damage identification and the use of large rupture strain fiber-reinforced polymer
(FRP) composites. The second part of the book presents key applications of FRP composites in bridge construction and
repair, along with the application of all-composite superstructures for accelerated bridge construction, engineered cementi-
tious composites for bridge decks, carbon FRP composites for cable-stayed bridges and for repair of deteriorated bridge
substructures, and finally the use of FRP composites in the sustainable replacement of aging bridge superstructures.
