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 use of concrete
- Spall Repair of Horizontal Concrete Surfaces
spalling Other common causes include freezing-and-thawing deterioration and chemical attack After an evaluation of the deterioration by an engineer, a plan should be developed including objectives and specificati ons for the repair Steps for repairs that include layout, removals, edge preparation,

High heating rates led to spalling close to the heated concrete surface Low heating rates caused spalling initiated from the core As simplification it is proposed to model concrete as “a pressure cooker” The analysis of the test results indicates that the simplified model may become an easy to apply tool for the prediction of spalling
- On Behavior of High-Strength Concrete Columns: Cover Spalling, Steel . . .
Keywords: column; ductility; high-strength concrete; reinforcement; spalling DOI: 10 14359 10301 Date: 7 1 2001 Abstract: It has been shown that the cracking at the cover-core interface, which proceeds cover spalling in high-strength concrete (HSC) columns, is a direct result of a triaxial stress condition

- Spall Repair by the Preplaced Aggregate Method
ances also contribute to cracking and spalling What is the purpose of this repair? Preplaced-aggregate concrete is used for repairs to restore structural integrity, provide extra cover, reduce the potential for shrinkage-related repair failures, and for underwater repair, particularly when cofferdams are impractical When do I use this method?
- International Concrete Abstracts Portal - American Concrete Institute
Spalling test results from 100 mm3 specimens revealed that moisture content and strength are the two main factors governing explosive thermal spalling of concrete Moisture content has a dominant influence on spalling The dependence of spalling on moisture content and strength confirmed the vapor pressure mechanism of spalling
