WEBINAR SERIES: Slag Cement in Concrete

The Slag Cement Association (SCA) is pleased to announce its slag cement webinar series featuring four webinars presented by industry experts. These free webinars are a great opportunity to learn about the different inherent benefits of slag cement when used in concrete construction. The webinars will start at the end of June.

The series includes:

Demonstrating Resilient Concrete Results with Slag Cement,

presented by Shawn Kalyn, St. Marys Cement,

Thursday, June 18 2020, 1-2PM EST

This webinar will discuss how slag cement and other supplementary cementitious materials (SCMs) can help reduce the carbon impact of concrete products and show attendees how to use industry wide documents and tools like Environmental Product Declarations (EPD), and Life Cycle Assessment (LCA) calculators.

The Role of Slag Cement in Creating Sulfate Resistant Concrete

 presented by Ryan Betz, Argos USA,

Thursday, July 9th 2020 1-2PM EST

This webinar will explore sulfate attack in concrete, how slag cement can be used to combat these affects and the testing methods used to prove its effectiveness.

Ground Granulated Blast Furnace Slags: Rapid Reactivity Testing and Effects of Varying Replacement Levels on Cement Paste Properties

presented by Sivakumar Ramanathan, University of Miami

Thursday, July 23rd 1-2PM EST

This webinar will feature a 2019 Slag Cement Research Project of the Year Award winner.

Mitigating Alkali Silica Reaction in Concrete with Slag Cement

presented by Keith Maddrey and Clayton McCabe, Argos USA,

Tuesday, August 18th 1-2PM EST

Adding slag cement to a concrete mixture design can help prevent alkali silica reaction (ASR), which leads to severe concrete cracking and deterioration. Illustrated through case study examples, this webinar will cover how slag cement works to mitigate ASR.

Evaluation of Ultra-High-Performance Concrete Mix Designs for Use in Bridge Connections and Repair 

presented by Trevor Looney, University of Oklahoma

Thursday, August 27th, 1-2PM EST

This webinar will feature a presentation one of the Slag Cement Association's 2018 research award winners.  An overview of the project and what will be covered is detailed below: 

The outstanding strength and durability properties of ultra-high-performance concrete (UHPC) make it an ideal material for use in infrastructure applications. The purpose of this study was to develop UHPC mix designs that were cost-effective and able to obtain comparable properties to commercially available products, then evaluate the performance of the best mix design when used as a joint material.

UHPC mix designs were evaluated using materials easily obtained in the state of Oklahoma such as Type I and III cement, Class C fly ash, VCAS 140 White Pozzolans produced by Vitro Materials, slag cement, silica fume, masonry sand, and a high-range water reducer. 

 Slag cement played a large role in the development of these mix designs. Even with large replacement levels up to 40% of total cementitious content, the developed UHPC mix designs performed as well as Ductal® in most tested applications. Furthermore, the slag cement improved the workability and ease of placement over conventional UHPC while reducing the overall cost of the mixes.
