EP #168: Are We Mishandling Concrete Admixtures?

PRESENTED BY: GPRS Construction professionals know that utilities and concrete reinforcements can cause big problems when you’re on the job. GPRS helps you avoid them. We use ground penetrating radar to detect rebar, conduit, and post tension cables before you cut, core, or drill. And our concrete scans are 99.8% accurate… we guarantee it—helping you reduce hits, downtime, expenses, and keep your people safe. To keep your jobsite safer, visit <a href="https://www.concretelogicpodcast.com/GPRS" target="_blank">https://www.concretelogicpodcast.com/GPRS</a> SUMMARY Concrete strength gets all the attention. But what if the real driver of concrete performance isn’t strength at all? In this episode of the Concrete Logic Podcast, Bob Higgins returns to talk about alkalinity — the chemical environment inside concrete that may control moisture behavior, curing, permeability, and long-term durability. Bob explains why alkalinity is often confused with pH, why salts inside concrete can trap moisture that testing methods never see, and why modern cement chemistry may be quietly changing how concrete cures and performs. If you’ve ever wondered why concrete behaves differently today than it did decades ago, this conversation will make you think.

EP #151: Most Concrete Durability Problems Start Here (Alkalinity Explained)

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 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
·&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Fiberglass rebar (GFRP) offers higher tensile
strength, lighter weight, corrosion resistance, and sustainability compared to
steel rebar.
·&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The adoption of GFRP is limited due to the need
for education and code updates.
·&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;GFRP has limitations in high seismic areas and
requires specialized detailing.
·&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Contractors can save costs by downsizing GFRP
bars and taking advantage of their material and labor efficiency.

EP #076: Lighten the Load - How to Remove Steel from Concrete

On today’s episode of the Concrete Logic Podcast, our guest is Garrett Braun, a structural engineer. Garrett is the founder of Blue Nest Structural. We discussed what it’s like to open a new firm in the last year, how far the design of projects is by the time his engineering group gets involved, why do engineers not consider changing materials in concrete mix designs, and why buildings are not designed with more concrete. 
To reach out to Garrett, email him at gbraun@blueneststructural.com or call 804-409-6272.

EP #001 - There's Not Enough Time for Concrete

Concrete Logic (Trailer)

What is the most used manmade material on Earth? You guessed it – concrete. 

In each episode of Concrete Logic, we will explore one concrete-related topic with the help of industry professionals that are shaping the future of the trade. We’ll talk with suppliers, contractors, architects, engineers, specialists, and even some proponents of competing materials about their views of concrete and their vision of its future.
