DEVELOPMENT OF A NATIONAL STANDARD
 FOR TESTING METHODS
 FOR SELF-COMPACTING CONCRETE MIXTURE

Abstract

In world practice, self-compacting concrete is
 increasingly used due to its unique properties
 and advantages. Self-compacting concrete
 mixtures have high ductility, better fluidity,
 high density with low water content due to the
 use of special effective mineral and chemical
 additives that provide high performance for
 concrete. The rheological properties of SCC
 differ significantly from those of conventional
 concrete. In this regard, when designing the
 composition of concrete and controlling its
 quality in laboratory and production conditions,
 several methods for controlling the quality of a
 self-compacting concrete mixture were created.
 The purpose of this standard was to create
 a single regulatory document regulating the
 assessment of the quality of a self-compacting
 concrete mixture.
 Concrete from a self-compacting mixture can
 be used for underground and hydrotechnical
 construction for the erection of structures of
 large length, complex geometric shape and
 densely reinforced structures.
