In this episode, Seth interviews Neel Khosa from AMSYSCO, a
post-tensioning supplier, to introduce post-tensioning and its history.
Post-tensioning is a form of concrete reinforcement that uses high-strength steel cables inside concrete. It is about five times stronger than conventional rebar and is used in pre-stressed concrete.
Unbonded post-tensioning is the standard for high-rise
construction and large concrete structures in the US. The advantages of post-tensioning include material savings, reduced construction time, improved seismic behavior, and reduced deflections and vibrations. The future of post-tensioning includes its use in office buildings and the development of new systems.

Summary
In this episode of Concrete Logic, Seth interviews Dr. Aaron
Fisher to discuss the use of fiberglass rebar (GFRP) as an alternative to steel rebar in concrete construction. He explains the fabrication process and the sizes available for GFRP. The advantages of GFRP over steel rebar include higher tensile strength, lighter weight, corrosion resistance, and sustainability.
However, the adoption of GFRP is still limited due to the need
for education and code updates. Dr. Fisher also highlights the limitations of GFRP, such as restrictions in high seismic areas and the need for specialized detailing. Aaron encourages contractors to consider GFRP as a cost-effective and durable solution for concrete reinforcement.
Takeaways
· Fiberglass rebar (GFRP) offers higher tensile
strength, lighter weight, corrosion resistance, and sustainability compared to
steel rebar.
· The adoption of GFRP is limited due to the need
for education and code updates.
· GFRP has limitations in high seismic areas and
requires specialized detailing.
· Contractors can save costs by downsizing GFRP
bars and taking advantage of their material and labor efficiency.

Summary
In this episode, Seth interviews Robert Higgins, a flooring concrete consultant specialist, about the issue of moisture in old concrete. Robert explains that moisture in older concrete is caused by a condition called ionic dew point, where particles migrate to the surface due to diffusion, not moisture migration.
He emphasizes the importance of addressing older concrete differently and recommends grinding off the surface to remove accumulated salts. Robert also discusses the acclimation of adhesive and flooring products to prevent moisture accumulation. He highlights the need for proper testing and understanding of environmental conditions to avoid moisture issues.
Takeaways
Moisture in older concrete is caused by ionic dew point, where particles migrate to the surface due to diffusion, not moisture migration.
Grinding off the surface of older concrete can remove accumulated salts and prevent moisture issues.
Adhesive and flooring products should be acclimated to the same temperature as the concrete to avoid moisture accumulation.

Summary
In this episode of the Concrete Logic Podcast, Dr. Jon
Belkowitz discusses the lack of accountability among civil engineers in the concrete industry. He highlights the disconnect between the design and implementation of concrete structures, with civil engineers often not present on job sites and lacking knowledge of concrete mix design. Dr. Belkowitz emphasizes the need for engineers to take responsibility for their designs and be held accountable for failures. He suggests that insurance companies and lawsuits may be the catalyst for change in the industry. Dr. Belkowitz proposes a new PE exam focused on concrete to ensure engineers have the necessary knowledge and understanding of the material.
Takeaways
Civil engineers in the concrete industry often
lack accountability for their designs and are rarely present on job sites.
Many civil engineers have limited knowledge of
concrete mix design and rely on ready mix providers for expertise.
The lack of concrete education in civil
engineering programs contributes to engineers' insufficient understanding of the material.
Copying and pasting solutions without fully
understanding the underlying principles is a common practice among civil engineers.
Insurance companies and lawsuits may be the
driving force for holding engineers accountable in the future.
A new PE exam focused on concrete could help
ensure that engineers have the necessary knowledge and understanding of the material.
