Workability maintenance of water-reducing admixtures in high-performance pastes produced with different types of Portland cement

ABSTRACT This work evaluated the efficiency and workability manteinance of a polyfunctional (lignosulfonate-based) and a superplasticizer (polycarboxylate-based) admixture in high-performance pastes (water/cement ratios of 0.30, 0.33 and 0.36) produced with two types of Portland cement (one pozzolan...
