Concrete is used in commercial struc- tures, transportation, water and

29、waste management, public works, farm construction, and utility and residential struc- tures. Based on the amount of concrete produced for each of these categories, residential construction accounts for the second largest application of concrete (PCA MI451D). 1.1Scope This guide provides practical in

30、formation 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 One- and Two-Family Dwellings” (International Code Council 2018) and that of ACI 332. Provisions of these c

31、odes apply to detached one- and two-family dwellings and multiple single- family 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

32、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

33、 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 prac- tice and should not be interpreted as meeting the requ

34、ire- ments 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 foun- dation systems (such as piles, drilled piers, or caissons), free-standing reta

35、ining 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 excep- tion of guidance on types of connections between the sill plate and foundat

36、ion 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).

CHAPTER 3CONCRETE 3.1Fundamen

49、tals The main constituents for concrete used in residen- tial construction include cementitious materials (portland cement and supplementary cementitious materials SCMs), coarse aggregate (stone or gravel), fine aggregate (sand), and water. Concrete mixtures have become much more complex in the range of additional components, as designers and contractors have been introduced to the benefits of performance-enhancing ingredients. These include a variety of chemical admixtures, fibers, and mineral pigments fo
