Mar 17, 2025 · Self-consolidating concrete (SCC) is highly flowable, nonsegregating concrete that can spread into place, fill the formwork, and encapsulate the reinforcement without any mechanical consolidation. In general, SCC is concrete made with conventional concrete materials and, in some cases, with a viscosity-modifying admixture (VMA).

The American Concrete Institute (ACI) is a leading authority and resource worldwide for the development and distribution of consensus-based standards, technical resources, educational programs, certification programs, and proven expertise for individuals and organizations involved in concrete design, construction, and materials, who share a commitment to pursuing the best …

Jan 7, 2015 · According to ACI 237R-07, Self-Consolidating Concrete, properly proportioned and placed self-consolidating concrete can result in both economic and technological benefits for the end user. The in-place cost savings, performance enhancements, or both, are the driving forces behind the use of self-consolidating concrete.

Self-consolidating concrete (SCC) is highly flowable non-segregating concrete that can spread into place, fill the formwork, and encapsulate the reinforcement without any mechanical consolidation. SCC is designed to have a rela-tively low yield stress compared to conventional concrete to ensure high flowability without segregation. Yield stress

The information in this document is expected to inform concrete producers, users, and specifiers of SCC of known practices and processes. Because SCC is a viable solution to various concrete placement problems, ASTM has established Subcommittee C09.47, Self-Consolidating Concrete, to develop standard test methods for SCC.

Consolidation methods and equipment should be included in project specifications. Except for projects that include self-consolidating concrete, consolidation should be an important part of every concreting job. References: ACI 318-19; ACI 301-20; ACI PRC-309.5-22. Topics in Concrete: Consolidation; Placing; Slab; Specifications

Self-Consolidating Concrete Testing Technician Training – 6 modules . This course contains six modules that prepare you for the ACI Self-Consolidating Concrete Testing Technician Certification Exam. Performance and written exams through a Local Sponsoring Group are required to become ACI Certified. Videos of test method procedures are included.

Jan 1, 2017 · Self-consolidating concrete (SCC) that has high flow rates and the ability to move through congested reinforcement is a new addition to VDOT concretes; it facilitates placement, minimizes consolidation problems, and improves structure longevity.

Apr 1, 2007 · The information in this document is expected to inform concrete producers, users, and specifiers of SCC of known practices and processes. Because SCC is a viable solution to various concrete placement problems, ASTM has established Subcommittee C09.47, Self-Consolidating Concrete, to develop standard test methods for SCC.

Jun 6, 2018 · “If you work with and test self-consolidating concrete on a regular basis, then make sure you are certified to do the job right.” Self-consolidating concrete is regularly used for cast-in-place projects, specialized applications, and is the primary product used in the precast industry. It was first introduced in the early 1990s.
