In this episode, Seth interviews Rich Szecsy, an executive in the concrete supply industry. They discuss the recent change in the batch time for concrete from 90 minutes to 120 minutes. Rich explains the history behind the 90-minute time limit and the lack of scientific justification for it. He emphasizes the importance of considering the practicality and sustainability of construction methods. They also touch on the topic of temperature specifications for concrete and the need for a more nuanced approach. Takeaways The 90-minute time limit for concrete batch time has been in place since the 1930s, but there is no scientific justification for it. The recent change to a purchaser-determined batch time allows for more flexibility and practicality in construction projects. Temperature specifications for concrete should be based on the specific conditions and requirements of each project, rather than arbitrary limits. The focus should be on building something and finding the most efficient and sustainable methods to achieve that goal. The responsibility of a concrete producer is to the purchaser, and specifications should be tailored to meet their needs and preferences.

In this Concrete Logic Podcast episode, Seth and Robert Higgins discuss the importance of curing concrete properly and the impact it has on the durability and sustainability of concrete. They highlight the historical practices of curing and how they have not evolved to keep up with changes in concrete composition. They also discuss the effects of temperature on curing and the role of alkalinity in concrete. The conversation emphasizes the need for improved curing practices to ensure the longevity and performance of concrete structures. Takeaways Proper curing practices are essential for the durability and sustainability of concrete. Historical curing practices have not evolved to keep up with changes in concrete composition. Temperature plays a significant role in the effectiveness of curing, with higher temperatures leading to faster curing but potentially weaker and more permeable concrete. Alkalinity in concrete, caused by changes in cement production and the use of additives, can affect the curing process and lead to weaker and more porous concrete. Improved curing practices can significantly increase the durability and sustainability of concrete structures.

In this episode of the Concrete Logic Podcast, Seth and Dr. Belkowitz answer questions from students at Virginia Tech about concrete mix design. They discuss the role of aggregate size in a mix design, its impact on the cost and control of the concrete, and the importance of a well-graded gradation. They also touch on the use of recycled concrete aggregate and its potential effects on the hydration process. The conversation highlights the economic and technical considerations involved in selecting the right aggregate for a concrete mix. Additionally, Dr. Jon and Seth discuss the impact of fines in aggregate on shrinkage, the seasonality of concrete work, and the decision-making process for choosing cement types in construction projects. They also share their favorite concrete mix designs. Takeaways Aggregate size in a concrete mix design affects the cost and control of the concrete. A well-graded gradation of rock and sand helps reduce the porosity index and the amount of paste needed in the mix. Recycled concrete aggregate can have contaminants that affect the hydration process and may require rock washing. Aggregate size can also impact shrinkage of concrete. Considerations for selecting the right aggregate include economic factors, availability, and technical specifications. The fines in aggregate, such as the fine particles that pass through a sieve, can have an impact on shrinkage and other properties of concrete. Concrete work is not necessarily seasonal, as there are techniques and materials available to pour concrete in various weather conditions.

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. Proper testing and understanding of environmental conditions are crucial to prevent moisture issues in flooring installations.
