Mass concrete is defined in ACI 116R as “any volume of concrete with dimensions large enough to require that measures be taken to cope with generation of heat from hydration of the cement and attendant volume change to minimize cracking.”
Version of Standard Specifications for Concrete Structures was established in 2008. Our task is to prepare the English version of four Specifications: ‘Design,’ ‘Materials and Construction,’ ‘Maintenance’ and ‘Dam Concrete’ of the 2007 edition of JSCE-SSCS.
Reinforced concrete wall is classified as: Plain concrete wall, when reinforcement < 0.4%; Reinforced concrete wall, when reinforcement > 0.4%; Load from slab is transferred as axial load to wall. When depth is large, it is called RC wall. Design is similar to a RC column, breadth equal to thickness of wall and depth equal to 1m.

14 cze 2023 · This document contains a history of the development of mass concrete practice and discussion of materials and concrete mixture proportioning, properties, construction methods, and equipment.
The rules of design as set forth in the present document are simplifications of the more elaborate requirements.
These sections cover materials and proportioning of concrete; reinforcement and prestressing steel; production, placing, finishing, and curing of concrete; formwork performance criteria and construction; treatment of joints; embedded items; repair of surface defects; and finishing of formed and unformed surfaces.
