ACI 301-20 (SI) PDF Download

ACI 301-20 (SI) is a Reference Specification that architects and engineers can use for projects involving concrete construction. It provides a checklist of mandatory and optional requirements that can be tailored to suit the specific project needs. The first five sections cover general requirements for concrete construction, including materials, proportioning, reinforcement, production, placing, finishing, curing, formwork, joints, embedded items, repair, and surface finishing. The specification also includes provisions for testing, evaluation, and acceptance of concrete and structures.

Additionally, the standard has sections dedicated to specific types of concrete construction such as architectural concrete, lightweight concrete, mass concrete, posttensioned concrete, shrinkage-compensating concrete, industrial floor slabs, tilt-up construction, and precast concrete. These sections provide guidance on the unique considerations and requirements for each type of construction.

It is emphasized that the materials, processes, quality control measures, and inspections described in this standard should only be performed by individuals who hold the appropriate ACI Certification or an equivalent qualification. This ensures that the construction and testing of concrete meet the necessary standards and requirements outlined in the specification.
