PERFORMANCE EVALUATION METHOD OF ENVIRONMENTAL LOAD REDUCTION CONCRETE

摘要

[PROBLEMS] To quantitatively evaluate both the effects of reducing carbon dioxide emissions achieved by using fly ash and ground granulated blast furnace slag and the effective use of resources, and the performance of environmental load reducing concrete, An evaluation method is provided that optimizes the materials and amounts used. According to the method of evaluating the performance of the environmental load reducing concrete of the present invention, various performance values of the standard concrete are measured and used as performance standard values, and the same water as the water / binder ratio of the standard concrete is measured. The various performance values of the environmental load reducing concrete having a binder ratio are measured and compared with the reference value, and the various performance evaluation values of the environmental load reducing concrete obtained from each comparison value satisfy a predetermined level, and It is a performance evaluation method for environmental load-reducing concrete, characterized by evaluating whether or not a comprehensive performance index evaluation value obtained by averaging performance evaluation values satisfies a predetermined level. Preferably, the various performances of concrete are strength development performance, environmental load reduction performance, crack resistance performance and durability performance, and the various performance evaluation values are 0.80 or more, more preferably 0.85 or more. It is evaluated whether or not the overall performance index evaluation value obtained by averaging various performance evaluation values of the environmental load reducing concrete from the value is 1.00 or more.
