Now, some technical standards based on the performance are established and examined in various fields. Views of the formation of the technical standards for port facilities based on the performance are introduced in this paper. Here, the concept of the performance of port facilities is arranged, and reconstruction of the systems for design, construction, and maintenance with revision of the standards is considered.

By-product's applicability to port and harbor structures is often studied. So, to use a large quantity of by-product's aggregates is desirable. However, if the aggregates include metal steel, metal steel volume will be increase by corrosion, then structures which include the metal steel aggregates may damage. Modified-sulfur concrete, which is made of byproduct's aggregates and modified-sulfur binder, has good properties such as high aggregate content, less water absorption, high strength, high salt resistance, good affinity for living organisms. This paper shows mechanical properties of “Modified-Sulfur Concrete” and its field tests under the sea.

Several componential analyses are used for concrete as usage, but since most of them are laboratory instruments, on-site analysis was very difficult. Recently, portable X-ray fluorescence analyzer have been developed, this enables us to carry out elemental analysis at the field. On-site analysis will provide improvement of working efficiency and the maintenance cost. It is said that energy dispersive X-ray fluorescence analyzers are not applicable for light elements such as sulfur or chlorine, but accurate experimental results were obtained to set proper measurement conditions. This paper introduces applicability of portable energy dispersive X-ray fluorescence analyzer for on-site elemental analysis of concrete and availability of the system.

Integrated studies at elementary school has been conducted since 2002. In this paper, it is reported the class for the integrated study about concrete engineering. Before the class, detailed investigation about the integrated study had done, and based on the results, the class about concrete engineering for the children in the third grade was carried out at Fujimi elementary school in Utsunomiya. In the class, it was explained about concrete material simply. And then several color mortar using white cement and some pigments were mixed and distributed to the children. Each child made wall decorates using color mortar he/she likes. After the class, the questionnaire was carried out and many favorable answers were found in them.
