New Japanese Industrial Standards of Test Methods for Concrete

Abstract

The JCI has been an organization to prepare drafts of Japanese Industrial Standards, JIS, of test methods for concrete since 1994. Nowaday, fifty JIS's of test methods for aggregate, fresh concrete and hardened concrete are established, and three JIS's of test methods for concrete was established in 2003. This report presents the new JIS's, i.e. “Method of accelerated carbonation test for concrete”, “Methods of test for chloride ion content in hardened concrete” and “Method of measurement for rebound number on surface of concrete”.
