JOURNAL FREE ACCESSThe history of cement industry and the change of cement technology are summarized and innovated research and development in the field of cement industry is discussed. In addition, special types of cement are classified from view points of the control of chemical and mineral compositions, the control of particle size distribution or the shape of particle, and the systems of ettringite formation. These properties are explained in this report.View full abstractDownload PDF (1685K) -

JOURNAL FREE ACCESSBased on papers concerning about full scale tests or site works, a state-of-the-art report on placing of concrete in concrete filled steel tubular columns is provided. Recent progresses in concrete technologies made it possible to fill concrete into steel tubular columns without any defects. Advises for filling works, data of concrete pressure, etc., and methods for non-distractive tests to detect defects in columns are described. Results of prework tests and quality control of concrete in three construction works, Yokohama Landmark Tower, Hosen Hotel, and Sinagawa Prince Hotel, are presented.View full abstractDownload PDF (985K) -

JOURNAL FREE ACCESSPCa permanent formworks are practically used for the purpose of labor-saving and time shortening. The half PCa permanent formworks of slabs and walls have been widely used, and recently thin PCa formworks are increasing in the field of architectures. In the field of civil structures the PCa permanent formworks of high durability not only for labor-saving are used.View full abstractDownload PDF (2393K) -

JOURNAL FREE ACCESSOne of the historical building which usually referred as “Red Brick Building” and was occupied by the Ministry of Justice, was designed by German architects Ende and Böckmann and was built in 1895. During World War II, it was heavily damaged by bombing and was restored later with major design changes. Recently, rebuilding work was carried out which included removal of the roof, replacement of the wooden floors by reinforced concrete floors and strengthening of the building in order to preserve and continue to utilize the present brick construction as the structural framework. Cornice stones and frieze stones etc. were replaced by precast artificial stones in order to restore the external appearance of the building to the state when it was first built. This report describes the results of investigations carried out with respect to the rebuilding work and the restoration of the original appearance using precast artificial stones.View full abstractDownload PDF (3036K) -

JOURNAL FREE ACCESSHankyu Hills Court Takatsuki 7 th is a 20 story high-rise reinforced concrete building which is used for condominium. We designed and constructed it by using the high strength concrete of Fc=600 kgf/cm2 and the high strength reinforcement of SD 490. Introducing these materials, we made it possible to reduce the section of columns and beams, and to decrease a number of reinforcement. We developed and made practicable the structural system 0. P. C. S. (OBAYASHI Progressive Concrete System) using precast reinforced concrete members cast on the construction site and to joint the horizontal reinforcement of beam in the beam-columnjoint. As a result of the above mentioned method, we have gotten the satisfactory results ; high constructability, shorter construction period, reduced resource requirements, and high quality. This report describes the design and structural system of precast reinforced concrete members cast on the construction site using the high strength concrete of Fc=600 kgf/cm2 and the high strength reinforcement of SD 490, and the concrete work and quality control for the high strength concrete of 600 kgf/cm2.View full abstractDownload PDF (2228K) -

JOURNAL FREE ACCESSThe conventional construction method of high pier has issues which needs large number of labor force and re-bar assembling, forming, scaffolding time. “Hybrid?Slipform Method” -A rational combination of a new concept of structural design and effective integration of construction techniques which enable the construction of high pier to be fast track using a reduced rabor force. In the first application of this method at Yokomiti Bridge, the time required for site operation was almost 60 % and the labor force was 70 % compared with the conventional construction scheme. In consequence, the new construction method would be applicable for construction of 50 to 100 m high pier with economical base.View full abstractDownload PDF (2054K) -
