Standardized Investigation Methods of Self Compacting Concrete and Effect of Sand Content on Properties in Fresh State

Abstract:

Investigation methods of self-compacting concrete (SCC) in fresh state in virtue of the new Hungarian standard are summarized. The referenced testing methods of former technological guidance were finally replaced by the MSZ EN 12350:2010 standards, part 8, 9, 10, 11 and 12, however momentarily these are only available in English. Besides testing methods, the requirements of MSZ EN 206-9:2010 Additional rules for self-compacting concrete reference titled standard are precedent. Neither of the currently used and standardized testing methods is suitable for collective evaluation of each special feature of SCC, thus these should be used coinstantaneously. Results of recent research work regarding change of SCC features by adding different amount of sand aggregate are presented in this article, too.
