Specifications for Repair of Concrete in Buildings—Everything 563 Shares with 301 Specifications (PDF)

Pdf Summary

The document outlines the proceedings and specifications discussed at The Concrete Convention and Exposition, focusing on structural concrete and repair standards set by two American Concrete Institute (ACI) documents: ACI 301 and ACI 563. 

<strong>ACI 301 Specifications:</strong> These are general guidelines for cast-in-place concrete projects, including various types such as architectural, lightweight, mass, post-tensioned, and shrinkage-compensating concrete. It covers aspects like industrial floors, tilt-up construction, precast structural, and architectural concrete. The document provides detailed sections on formwork and accessories, reinforcement supports, and concrete mixtures, specifying standards for performance, design, handling, placing, and constructing concrete.

<strong>ACI 563 Specifications:</strong> This document is specific to the repair of concrete in existing structures and covers general requirements, formwork, reinforcement supports, and conventional concrete mixtures. It’s distinctively focused on the standards necessary for repairing damaged or deteriorated concrete, including definitions for repair-specific terms like delamination and microcracks. ACI 563 also outlines procedures for quality assurance, testing, inspection, and the involvement of repair material manufacturers.

<strong>Standards and Testing:</strong> Both ACI 301 and ACI 563 reference numerous standards, including ASTM guidelines for testing tensile strength and bonding properties. This ensures that repairs and new constructions meet stringent quality and performance benchmarks.

<strong>Material and Execution:</strong> The documents specify the types of materials approved for use, detailing aspects like alkali-silica reactivity and prohibiting certain compounds, such as calcium chloride, in repair activities. Execution involves ensuring compliance with dimensional tolerances and existing conditions, with sections on mock-ups, adhesive anchors, and cleaning existing reinforcements.

The conventions emphasize procedural adherence, quality management, and technical support to maintain structural integrity in both new constructions and repairs.
