Outline of Final Research Achievements

To apply the granulated blast furnace slag (GBFS) to the SCP method with the low sand replacement area ratio, by mixing the natural sand with GBFS at the various sand mixing ratios in the range from 0% to 40%, the specimen was cured in the water and the change of the unconfined compressive strength, hydration reaction ratio and the permeability were measured with time. The main conclusions are as follows. ①By mixing the natural sand with GBFS, the development of hydration is inhibited. ②The curing duration until when the unconfined compressive strength starts to increase is the same irrespective of the natural sand mixing ratio. ③The hydration reaction ratio and the unconfined compressive strength decrease with the natural sand mixing ratio. ④By mixing the natural sand with GBFS, a larger permeability was confirmed at the beginning of curing. ⑤When applying GBFS to the SCP method with the low sand replacement area ratio, the most appropriate natural sand mixing ratio would be 30%.
