INSIDE ICC ICC Evaluation Service (ICC-ES) Where Innovation Meets Safety in the Construction Zone ICC Evaluation Service Provides Tools to Confidently Approve Innovative or Unfamiliar Building Products for Installations Featured Innovation: Acceptance Criteria for Proprietary Hydraulic Cement (AC459) This acceptance criteria (AC) establishes requirements for proprietary hydraulic cement to be recognized in an ICC Evaluation Service, LLC (ICC-ES), evaluation report under the 2012 International Building Code® (IBC) and the 2012 International Residential Code® (IRC). Bases of recognition are IBC Section 104.11 and IRC Section R104.11. This acceptance criteria applies to proprietary hydraulic cement, consisting of hydraulic pozzolans and proprietary additives but contains no Portland cement. The hydraulic characteristics of the pozzolans used in the hydraulic cement are modified by proprietary additives to control the rate of setting and improve the properties of the hardened concrete in which it is used. Depending on the formulation, chemical modifiers used in production of the cement are either liquids or dry powders. This criteria is intended to demonstrate that proprietary hydraulic cement will comply with the requirements in ASTM C1157 for Type GU cement and meet or exceed the physical performance specifications contained in ASTM C150, referenced by the ACI 318 for Type I or Type II. Code officials can have confidence in approving these products when they have an ICC-ES Evaluation Report. Evolution in the construction industry is constantly bringing new technologies and materials to the marketplace and construction zones, raising questions about building safety and proper installations, and demanding time and resources from code officials and building professionals throughout the country. The progress in building materials and technologies is natural and unavoidable. ICC-ES provides resources to code enforcement and other industry professionals to ease their work and provide them peace of mind—ICC-ES Evaluation Reports. With more than 80 years of experience and the premier platform for development of Acceptance Criteria for innovative products, ICC-ES develops the tools and Evaluation Reports that the construction industry relies on.
