Standard Practice for Installation and Testing of Reinforced Autoclaved Aerated Concrete (AAC) Units
SIGNIFICANCE AND USE
5.1 This practice is intended to regulate the installation of reinforced AAC units and to provide test methods for determining their transverse load-displacement characteristics and load-carrying capacities.
SCOPE
1.1 This practice covers the installation and testing of solid, reinforced units made from autoclaved aerated concrete (AAC), a cementitious product addressed by Specification C1693. The units are large-sized, factory-reinforced, solid rectangular prisms, laid using thin-bed mortar.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview
ASTM C1686-09(2017), issued by ASTM International, establishes standardized practices for the installation and testing of reinforced autoclaved aerated concrete (AAC) units. AAC is a lightweight, cementitious material formed into large, solid, factory-reinforced rectangular blocks, typically joined with thin-bed mortar. This standard ensures that construction involving reinforced AAC units is performed using consistent installation methods and reliable testing procedures to determine structural performance, specifically transverse load-displacement characteristics and load-carrying capacity.
Key Topics
Scope of Practice
- Covers installation and testing procedures for solid, reinforced AAC units conforming to ASTM C1693.
- Values provided in inch-pound units as standard, with metric conversions for reference.
- Developed in accordance with WTO guidelines for international standards.
Installation Requirements
- Units must be protected from direct moisture exposure using manufacturer-approved coatings.
- Installation methods should maintain integrity, handling, and alignment of units.
Shipping, Handling, and Repair
- Elements are to be safeguarded during transit utilizing pallets, banding, or separators as specified by the manufacturer.
- Damage must be repaired using AAC-compatible mortars or, if severe, evaluated for structural integrity by the manufacturer. Exposed reinforcement must receive corrosion-resistant coatings.
Field Modification
- Field cutting of reinforced elements is not permitted unless approved by the project engineer and conducted according to manufacturer guidance.
Testing Protocols
- Provides procedures for assessing load-displacement characteristics using prescribed apparatus.
- Detailed instructions for placement, loading rates, measurement, and failure assessment.
- Test specimens must reflect field conditions, including temperature and moisture content.
Acceptance and Rejection
- Elements failing to meet standard requirements at delivery can be repaired or replaced in accordance with manufacturer recommendations.
- Expenses for inspection and testing are typically the responsibility of the purchaser.
Applications
- Structural Elements: Ideal for walls, floors, and roofs in residential, commercial, and industrial construction where lightweight and thermal insulation properties are desirable.
- Quality Assurance: Ensures structural performance and consistency of AAC installations by providing standardized installation and testing procedures.
- Inspection and Compliance: Facilitates verification by regulatory authorities, project managers, and quality control professionals to ensure conformity with international building codes and ASTM standards.
By adhering to ASTM C1686, construction professionals and manufacturers can achieve reliable, safe, and high-performing AAC structures, reducing the risk of installation or performance failures.
Related Standards
- ASTM C1693: Specification for Autoclaved Aerated Concrete (AAC), referenced for defining material requirements.
- Referenced Procedures and International Guidelines: Developed in accordance with the World Trade Organization's Technical Barriers to Trade (TBT) Committee principles.
- Other ASTM Standards: The document may refer to further ASTM practices in precast and concrete product categories, facilitating cross-standard harmonization.
