About this file
This is a technical specification document for metallic non-shrink grouting at Tinker Air Force Base, Oklahoma, issued in April 2019 as Section 03 62 16.
The specification establishes requirements for Type A expansive grout containing an oxidizable metallic aggregate and oxidation-promoting ingredient. Materials required include Type I Portland cement conforming to ASTM C150/C150M, aggregates meeting ASTM C33/C33M standards, potable water, and expansive admixtures consisting of oxidizable metallic aggregates. The contractor must submit samples of expansive admixtures and expansive grout to the Contracting Officer prior to work commencement for review and acceptance. Government approval is required for submittals including test reports for expansion and compressive strength, and certificates for Portland cement, expansive admixtures, expansive grout, and aggregates. Preparation requires cleaning cavities of foreign matter, laitance, dirt, grease, or oil, with all contact surfaces cleaned no less than 24 hours before grout application. Mixing must follow manufacturer's written instructions using proper mechanical mixers located as close to the work area as possible. Grout placement must comply with manufacturer's written installation instructions and cannot be used if it has begun to set or if more than one hour has elapsed after initial mixing. Blind cavities shall be filled by pressure injection under controlled venting at 60 psi. Field quality control requires testing per ASTM C1107/C1107M with performance requirements of 0.0 to 0.3 percent expansion at 28 calendar days and minimum compressive strength of 5,000 psi. The contractor must provide grout placement plans and inspection reports in accordance with ACI standards at least 4 calendar days prior to commencement of work.
