Standard Specifications for Concrete Structures “Materials and Construction” consists of “General Requirements”, “Construction Standards”, “Inspection Standards”, and “Special Concrete”.

“General Requirements” presents the fundamental concepts of construction plan, quality control, inspection, and construction records in the constructions according to the principles of performance specification, so that the qualified concrete structures can be constructed without fail even under special conditions such as construction using new material or new method. In a construction plan, for example, plan for transporting and receiving concrete, haul road plan, placement plan, compaction plan, finishing plan, curing plan, jointing plan, reinforcement work plan, framework and falsework plan, and safety and health plan are listed as consideration items, and it’s written in the “General Requirements” that in case overall construction plan cannot be compiled in a reasonable way based on these respective plans, it should be returned to the designing step and request for modification of conditions of design documents.

“Construction Standards” shows standard materials and construction methods, which can be used as the common specification. Introducing new materials or new technologies that are becoming more and more common, and considering the recent climate conditions or economic situation, “Construction Standards” shows the standard materials, mixing, and construction methods that enable a high-quality concrete structure. By following these standards, concrete structures of a certain level of quality can be constructed without special attention in concrete works for the construction of an ordinary civil engineering structure.

“Inspection Standards” is compiled for the Owner to conduct an appropriate inspection in each phase of concrete work in the construction of an ordinary civil engineering structure and at the completion of the structure. As the inspection items in “Inspection Standards”, inspection for acceptance of constituent materials of concrete, inspection of concrete production facilities, inspection for acceptance of ready mixed concrete, acceptance of inspection for reinforcement, inspections of construction, and inspection of concrete structure are listed.

“Special Concrete” covers standards concerning the matters required for producing or constructing concrete structures that involve special materials, functions, construction methods, construction environment, structural formats and production methods. Information on plasticized concrete, high fluidity concrete, high strength concrete, expansive cement concrete, short fiber reinforced concrete, offshore concrete, underwater concrete, shotcrete, prestressed concrete, industrial products, lightweight aggregate concrete, and prepacked concrete are compiled. The characteristic point of this section is that it is written with focus on specification code considering the practical usability.
