Abstract

The Guidelines for Design and Construction of Grouting for Prestressed Concrete Structures, established in 2005 by the Japan Prestressed Concrete Institute, have been revised for the first time in seven years. Among the major revisions are 1) the clarification of the necessary qualifications of engineers involved in PC grouting work, 2) the update of the materials used to the latest version, 3) the clarification of the positioning of full-scale tests, 4) the clarification of priorities regarding mixing, 5) the clarification of the period from after prestressing steel insertion to PC grout injection, 6) the reduction of the guaranteed material ages for the compressive strength test, and 7) changes to the frequency of routine control tests according to actual conditions.
