Practical Consideration of Shrinkage-Reducing Superplasticizer by Mock-up Test
초록
영어
This paper reports the results of Mock-up test for concrete using drying shrinkage reducing superplasticizer(DSRS) in order to evaluate the validity of DSRS. The use of DSRS results in an noticeable improvement in compressive strength compared with other concrete. Drying shrinkage of concrete using DSRS is lower than that of conventional concrete by as much as 17%
due to less water content and contribution of expansive additives to expansion of specimens. Drying shrinkage measured by contact gauge has the highest value at the thin section of the mock up member such as near the window. The use of DSRS can reduce drying shrinkage by as much as 15~30% comapared with conventional concrete member.
