2024/10/12 11:39

The American Concrete Institute (American Concrete Institute) was founded in 1904, formerly the American Cement Users Association, headquartered in Farmington Hills, Michigan. ACI is a non-profit technical research group and standards-setting organization, the world's leading authority on concrete technology. is the authority and provides professional consulting services to individuals and organizations involved in concrete design, construction and materials, and is committed to achieving the best use of concrete in the construction field. ACI has more than 100 chapters, 200 student chapters and 30,000 members in 120 countries or regions around the world.

ACI aims to strengthen engineering technology education and scientific research, and to develop design and construction standards for concrete and related materials. In order to promote the improvement of concrete technology, technology, design and construction, the society should continuously improve and optimize the design, construction, manufacturing, use, maintenance and repair of concrete and related materials, and organize its members to carry out related non-profit public services, so as to achieve A vision to benefit society.

ACI has sorted out more than 100 topics related to concrete for contractors, and provides certification, online teaching, journals, papers, public publications and exclusive services for specific projects.

ACI Concrete Technical Document Classification and Application Guide

The technical documents released by ACI are divided into two forms: standard and non-standard.

ACI standards are mandatory (written in mandatory language) and include design and construction categories:

Design standards: applicable to designers, involving specification requirements, specification cases, acceptance standards, and design technical requirements.

Construction standards: applicable to construction personnel, involving construction technical requirements and material technical requirements

Non-standard documents include guidelines, reports and technical notes (Non-standards Guides and Reports):

Guidance: Optional, provides recommendations for analysis, design, specification, selection, evaluation, testing, construction or repair activities of concrete materials or structures; Report: Provides information on concrete technology within the committee's area of expertise;

Technical Note: Provides guidance on specific issues.

Nearly 700 technical documents, manuals, instructions, reports, guidelines, corrigendums, papers, technical requirements and specifications related to concrete have been formulated. The standard classification is based on the code name of the formulation committee. The code distribution is as follows:

• ACI 100 – General Provisions

• ACI 200 – Concrete Materials and Properties

• ACI 300 – Design and Construction Procedures

• ACI 400 – Concrete Structural Analysis

• ACI 500 – Special Applications and Repairs
