ACI considers cracks, other concrete issues

The American Concrete Institute has released five new publications:

224.1R-07: Causes, Evaluation, and Repair of Cracks in Concrete Structures — This publication summarizes the causes of cracks in concrete structures, presents procedures used to evaluate cracking, and describes techniques for crack repair.

332.1R-06: Guide to Residential Concrete Construction — This guide covers concrete work for one- and two-family dwellings with a maximum height of two stories above grade and a basement that is either cast-in-place or placed as precast elements. Information on materials, proportions, production, delivery, and testing is provided. Separate chapters on footings, walls, and slabs provide information on subgrade, forms, reinforcement, placement, consolidation, finishing and curing. Insulation and hot and cold weather are considered. Common problems and repair solutions are also addressed. The discussion of specific design provisions and all drawings provided by this guide are intended to offer illustrations of typical practice and should not be interpreted as meeting the requirements of specific codes or project specifications.

350-06: Code Requirements for Environmental Engineering Concrete Structures and Commentary — This document covers the structural design, materials selection, and construction of environmental engineering concrete structures used for conveying, storing, or treating liquid or other materials, such as solid waste. This code presents new material as well as modified portions of the ACI 318-02 Building Code that are applicable to environmental engineering concrete structures. ACI 350-06 is written as a legal document.

437.1R-07: Load Tests of Concrete Structures: Methods, Magnitude, Protocols, and Acceptance Criteria — This report provides recommendations regarding selection of test load magnitudes, protocol, and acceptance criteria to be used when performing load testing as a means of evaluating safety and serviceability of concrete structural members and systems.

546.3R-06: Guide for the Selection of Materials for the Repair of Concrete — This document provides guidance on the selection of materials for concrete repair. It offers an overview of the important properties of repair materials.
