Self-Consolidating Concrete (SCC) is a high flowing, stable concrete that can be used as a practical solution for many challenging placement scenarios because it does not require vibration or mechanical agitation for consolidation. Since its introduction, concrete professionals continue to find new applications for SCC to solve concrete construction problems. In an environment of economic considerations, sustainable building practices, increased speed of construction requirements, and high structural integrity, SCC can play an important role in achieving these demands. This session will highlight the use of SCC as a solution to challenges for many unique projects and enhance construction productivity and sustainability. Case studies will be presented and include concrete placement in congested reinforcement, cast-in-place and precast/prestressed elements, challenging conditions involving restricted access, long-haul scenarios, extended pumping conditions, underwater concreting, and Artificial Intelligence (AI) implementation. The presentation will bring insight and awareness to the opportunities for SCC use in future concrete construction that otherwise may not have been considered.
Self-Consolidating Concrete as a Solution for Unique Applications Additive Construction of Low Embodied Carbon Concrete

Affiliation: Master Builders, Inc.
Description: Self-Consolidating Concrete (SCC) is a high flowing, stable concrete that can be used as a practical solution for many challenging placement scenarios because it does not require vibration or mechanical agitation for consolidation. Since its introduction, concrete professionals continue to find new applications for SCC to solve concrete construction problems. Admixtures including high-range water reducers, viscosity modifiers, set controlling admixtures, and others allow concrete producers to develop customized mixtures to meet performance requirements for projects. In an environment of economic considerations, sustainable building practices, increased speed of construction requirements, and high structural integrity, SCC can play an important role in achieving these demands. This presentation will highlight the use of SCC as a solution to challenges for many unique projects. Case studies will be presented and include concrete long-haul scenarios, underwater concreting, slump flow retention requirements, high-early strength demands, concrete paving, QC management using digital tools, congested reinforcement, and Artificial Intelligence (AI) implementation. The presentation will bring insight and awareness to the opportunities for SCC use in future concrete construction that otherwise may not have been considered.
Enhancing SCC Productivity and Performance through Quality Control
Presented By: Calvin McCall
Affiliation: Concrete Engineering Consultants Inc
Description: While mechanical properties are always important in all concretes, workability properties must be met in SCC. If the workability properties are not met, there is no vibrator to enhance workability. SCC concrete is a special type of concrete that needs to have predictable properties throughout the placing process. This presentation discusses methods that can be performed in the laboratory to predict the workability at the time of delivery.
Beyond the Mix: The Art and Science of SCC
Presented By: William Denison, Jr.
Affiliation: ECS MID-ATLANTIC LLC
Description: Self-consolidating concrete (SCC) represents a revolutionary advancement in concrete technology, designed to flow and settle into formwork with minimal vibration. This Self Consolidating innovation not only improves the efficiency of construction but also enhances the structural quality and durability of concrete structures. SCC’s self-leveling properties are resilient and sustainable, reduce labor costs, improve worker safety, and allow for the construction of complex architectural designs including concrete placement in congested reinforced concreting elements, Cast-in-Place, and Massive Marine concrete structures. This presentation will explore the composition, benefits, applications, and future potential of self-consolidating concrete in modern construction.

Description: The commercial tower at 141 Bay Street is an exciting project that will add to Toronto’s beautiful skyline in 2025. This presentation will discuss the use of SCC from the producer’s perspective – and detail challenges and success in proper design, testing and placement of SCC.
To SCC or Not to SCC - Answering the Question
Presented By: Terry Harris
Affiliation: Saint Gobain - Chryso
Description: We often see specifications for projects that specify a maximum slump for concrete mixtures that will include a HRWR admixture. These specifications typically cap the slump at a maximum of 8 inches (200 mm). However, is that truly the best concrete mixture for the application? We will show how we approach mixture development with HRWRs, including how we determine whether an SCC mix is right for a project or for the specified mix. We will then show how this has been applied through case studies.
Using SCC to Enhancing Productivity and Achieve Cost Savings on your Construction Job - Reduction Project Cost

Affiliation: Webcor Builders
Description: ACI Committee 237 is working on the final chapters of a state-of-the-art report for self-consolidating concrete (SCC). Chapter 10 of this report is titled, “Economic Considerations.” SCC was first developed in Japan in the 1980’s with the intention of addressing labor shortages. Since then, many advantages and challenges have evolved during the history of its use. This presentation will provide relative cost comparisons of common uses of SCC, to conventionally vibrated concrete (CVC) for the same applications. While the potential for cost savings of using SCC exist, depending upon the experience of the concrete supplier and the concrete contractor, the advantages are not always realized. The more experienced concrete producers and concrete contractors are in the production and placement of SCC, the beneficial the economic outcome is. The purpose of the presentation is to identify the relative cost differences between SCC and CVC and actions which can be taken to capitalize on SCC’s potential to reduce project costs.
