Type IL: - The “New” Cement on the Block –
Portland Limestone Cement (.5 PDH)
Type IL cement is a more sustainable, lower
carbon cement that reduces CO2 emissions by up
to 10% while still producing concrete performance
equivalent to ordinary type I portland cement.
To understand the push for PLC’s we must first
understand carbon. There are two types of carbon
that we must look at, Embodied and Operational
Carbon. While there are many benefits of using
a PLC, there are some challenges that should be
recognized, both in production and finishing of
concrete.
Improving Sustainability in Construction
with Concrete: Codes, Specifications and
Requirements (.5 PDH)
Prescriptive vs Performance based design and
how it relates to improving sustainability of
structures. How design can help lower the carbon
footprint of the building and help achieve net zero
emissions by 2050.
Expect Compressive Strength Test Results
Less Than Specified Strength on Every Project
(.5 PDH)
On every project, experienced concrete
industry professionals recognize that individual
compressive strength test results can be lower
than the specified strength, f′ c. While there are
numerous reasons this might occur, one important
reason is: the standards for acceptance criteria
used in the United States are based on statistical
concepts that permit a low-test result, and it
is standard practice for concrete producers to
design concrete mixtures based on a probability of
about 10% that an individual strength test may be
less than f′ c.
Designing for Durability (1 PDH)
Concrete is a versatile construction material
that can be used in a wide range of service and
environmental conditions. Conditions that can
impact service live of concrete structures should
be identified during design and addressed in
project specifications. To address durability of
concrete, ACI 318, Building Code Requirements
for Structural Concrete, has specific requirements
for concrete for defined environmental exposure
conditions. This presentation will cover why
and how durability should be addressed and
consideration of other durability considerations
such as cracking, thermal gradients, abrasion, and
alkali silica reactions.
A Day in the Life of a Concrete Cylinder (1 PDH)
The importance of testing concrete in the field
is often underestimated and overlooked. The
need for certified personnel both in the field and
laboratory is imperative. There are many factors
that may contribute to low cylinder strengths on
a project, and many of those factors could be
avoided. This presentation will look at the “cost”
of low cylinder breaks and the necessary steps to
insure proper testing and cylinder care in the field.
