A shrinkage-reduction admixture is used in order to prevent such plastic shrinkage cracks. Although the cracks can be avoided by this method, white powders of CaCO3 sometimes appear on the surface. The effects of the admixture and curing condition were investigated on the amount of powders and the bond strength. It was found that appropriate addition of the admixture successfully reduces the plastic shrinkage cracks without producing powders on the surface.}, pages = {31--35}, title = {真空脱水コンクリート床スラブの表層に発生する微細ひび割れの低減に関する実験的検討}, volume = {17}, year = {2011} }
