ACI 301-20 (IN-LB) PDF Download

ACI 301-20 (IN-LB) is a comprehensive reference specification that can be used by architects and engineers for projects involving concrete construction. It is intended to be cited in the project specification and provides a mandatory requirements checklist and an optional requirements checklist. These checklists assist the architect/engineer in supplementing the provisions of the specification as needed for individual project requirements.

The first five sections of ACI 301-20 cover general requirements for concrete construction, including materials and proportioning of concrete, reinforcement and prestressing steel, production, placing, finishing, and curing of concrete, formwork performance criteria and construction, treatment of joints, embedded items, repair of surface defects, and finishing of formed and unformed surfaces. The specification also includes provisions for testing, evaluation, and acceptance of concrete, as well as acceptance of the structures.

Furthermore, ACI 301-20 addresses specific types of concrete construction, such as architectural concrete, lightweight concrete, mass concrete, posttensioned concrete, shrinkage-compensating concrete for interior slabs, industrial floor slabs, tilt-up construction, precast structural concrete, and precast architectural concrete.

It is important to note that the materials, processes, quality control measures, and inspections described in this specification should only be performed by individuals who hold the appropriate ACI Certification or equivalent qualification.
