Liquid concrete and self-compacting concrete

The article presents research on the influence of the complex additives based on superplasticizer S3 on workability of concrete of conventional composition (suitable for pumping on the concrete pipelines), obtaining an antifloated of concrete mix of a floated consistence for vibrationless placing. Conducted an analysis the new self-compacting concrete mix. These compounds at this stage of the development of are novel and abroad and in Russia. The article presents comparison of the self-compacting concrete with a flow concrete mixes, which under certain conditions may be similar to those of self-sealing mixtures. Concluded that with using the intersection of mixtures with of the possible replacement self-mixtures on the cast, there are the most economical.
