There are five commonly used procedures for designing industrial floor slabs. All of them are effective when their recommendations and details are followed. So, how does a designer choose the best method for a particular floor? The most common approach is to determine the type of floor construction needed for expected loading conditions. Then, from the design procedures, select the most appropriate method for determining floor thickness, reinforcement, joint spacing, and other details. This presentation will discuss the ACI 360 “Guide to Design of Slabs on Ground”. It will briefly address the planning, design, and detailing of slabs. Background information on design theories is followed by discussion of the types of slabs, soil-support systems, loadings, and jointing. Some worked design examples for various types of concrete slabs-on-ground will also be covered.

This presentation reviews failures, damages, and other incidences of poor performance in concrete structures that have served to shape today's building codes and the standard of care for the profession. Examples range from well-documented, high-profile collapses to lesser known but similarly influential structural and serviceability problems. Case histories will include discussion of excessive cracking, the cause of such distress, and mitigation measures. The case histories will illustrate how small details can often mean the difference between success and disappointment; and how codes have evolved to reduce the risk of future failures.

This presentation will discuss changes in the volume of air entrained concrete in pumped concrete. The work shows that during pumping the air volume will decrease and if measured immediately after pumping will be lower than what is found in the final concrete. These findings are supported by hardened air void analysis, freeze thaw tests, and measurement of the air void volume and spacing over time in the fresh concrete with the Super Air Meter. The presentation makes recommendations for modifications to the current testing specifications based on the findings.

This presentation will discuss materials being developed for the concrete industry that will lower the embodied carbon of a yard of concrete. Some materials are ready to use and do not require additional support or alteration of how we produce, place, and finish concrete. Others will require new approaches, new specification, and new understanding of chemistry.
No credits will be awarded for viewing recordings of the webinar.
The webinar is being sponsored by the Iowa Ready Mixed Concrete Association, the Minnesota Concrete Council, the North Dakota Concrete Council, the Oklahoma Ready Mixed Concrete Association, the South Dakota Ready Mix Association, and the Wisconsin Ready Mixed Concrete Association.

This webinar will outline the benefits of using Insulated Concrete Forms (ICFs) in construction, especially in regard to Rural and Tribal projects. ICFs are a key component in DSGW’s strategy to design Net Zero projects. This presentation will show examples of ICF and Net Zero design, in particular the Fort Totten Alternative CTE School, the country’s first Net Zero school on Tribal lands in North America.
The 12,500 square foot, $3.8 million net zero Fort Totten Alternative CTE School was designed to produce more energy than it consumes while ensuring to meet other standards common when designing a net zero facility. There are other net zero schools in the United States, but this new school is the first to be built on tribal land and the first in North Dakota.

Ultra High Performance Concrete (UPHC) describes a class of concrete material with a unique set of properties including: Strengths of 21,000 ksi plus, high ductility, low permeability and rapid strength gain. With these unique material properties, UHPC facilitates short development lengths, thin overlays and the potential for further development in optimized prestress girders for longer spans with less material. UHPC continues to play an important role in Accelerated Bridge Construction serving as the connecting material between precast elements allowing for small joints with short lap lengths while obtaining full connectivity between the elements. This presentation will introduce the audience to UHPC, the basic material properties, applications and lessons learned.
