ACI 332.1R

Abstract

This guide provides practical information about the construction of residential concrete that meets or exceeds code requirements, covering all concrete work within the scope defined in the “International Residential Code for Oneand Two-Family Dwellings” (International Code Council 2018) and that of ACI 332. Provisions of these codes apply to detached one- and two-family dwellings and multiple singlefamily dwellings (townhomes) not more than three stories in height. These structures are no more than three stories above grade and may include a basement that is either cast-in-place or placed as precast members. 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. Special considerations regarding above-grade concrete systems in Chapter 6 and project considerations in Chapter 8 are included. Common problems and their repair 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. Applicable codes and construction documents take precedence over the information contained in this document. Information excluded from this guide includes deep foundation systems (such as piles, drilled piers, or caissons), free-standing retaining walls (greater than 4 ft [1.2 m]), and post-tensioned slabs-on-ground. Limited information on the use of lightweight concrete is presented. This guide does not cover loading and design for seismic forces, with the exception of guidance on types of connections between the sill plate and foundation wall commonly used in higher seismic design categories. Additional information on seismic loading and design can be found in the “International Residential Code for One- and Two-Family Dwellings” (International Code Council 2018).
