Problem eliminacji niepożda̧nych pȩcherzyków powietrza w przypadku SCC

The obtaining non-entrained self-compacting concrete problems are considered in the paper the superplasticizer air-entraining adverse effect is problematical to obtain the non-entrained self-compacting concrete. Rheological requirements to decrease the air-entrainment of self-compacting concrete are reasoned. To decrease of air-entrainment of SCC we should use: superplasticizers with non air-entraining effect or the anti-foaming admixture. Moreover, we can to change the composition of SCC to decrease of air-volume.
