    The Standard Specifications for Concrete Structures were revised and published by Japan Society of Civil Engineers in December 2007. The 2007 edition was consisted of 5 parts, “Design”, “Materials and Construction”, “Dam Concrete”, “Maintenance” and “Standards for test methods and material quality”. This paper describes main revisions in 4 parts excluding “Standards for test methods and material quality”. Having in mind for making the specifications convenient to practicing engineers, the revision was carried out to maintain the least requirements for introducing the up-to-date developments in concrete technology, to optimize the current performance-based specifications and to synchronize all constituent parts so as to create a perfect connection between different parts. It is believed that this revision is a fine integration between the rationality based on performance verification concept and the practical applicability.

    During the global environment protection has become more and more interested, the finishing materials of concrete surface can be said to be the materials contributing to improving durability of structure, as they have the effect of suppressing concrete carbonation in structure. It is important to evaluate adequately and to share the data with the effect of suppressing concrete carbonation, regardless of in construction or in repair. In the committee of BCS-Building Contractors Society, the members have been carrying out to evaluate finishing materials with contribution to suppression of concrete carbonation objectively by arranging the existing research and the experiment results. In this report, the authors describe the results of evaluating various finishing materials with regard to contribution to suppression of concrete carbonation, by means of the rate of carbonation and the coefficient of permeability as an index.

    Authors were able to acquire the performance evaluation of high strength pre-cast concrete using 150 MPa concrete, In this report, it explains the flow of the performance evaluation acquisition with such a case. Moreover, authorsdid an actual manufacturing about high strength pre-cast concrete using 150 MPa that received the performance evaluation.As a result, 150 MPa concrete with a very steady quality could be manufactured.
