JOURNAL FREE ACCESSVarious building materials and structures mainly of cement and concrete are re-examined and compared with others in terms of energy conservation. Construction energy and thermal properties of such structures are also examined. Under the same condition, Portland cement and reinforced concrete structures prove less energy-consuming than steel and its structures, for example. Cement and concrete, being quite flexible in shape, strength, density and thus thermal properties, are readily adjustable and desirable to our energy-conscious age.View full abstractDownload PDF (1212K) -

JOURNAL FREE ACCESSFor the construction of Tokai Plaza Building in Yokohama, superplasticized concrete was adopted. Superplasticized lightweight concrete which was placed for higher floors was pumped up to 80 m of the roof floor from the ground. Water content of this light-weight concrete was 181 kg per m3 and its specific gravity was 1.6 with its slump of 18 cm. This report describes the site experiments of the plasticized concrete and the concreting on the 25th floor.View full abstractDownload PDF (2191K) -
