Dehydration phase has strong adsorption. The compatibility of polycarboxylate superplasticizer with dehydrated phase directly affects the performance of UHPC. In this study, three kinds of superplasticizer were used to explore the influence of superplasticizer on workability, rheological properties, mechanical properties of UHPC prepared by dehydrated phase as well as their compatibility. The results show that SPT and A97BS superplasticizer can increase the plastic viscosity of ultra-high performance concrete paste prepared by adding dehydrated phase, and can optimize its working performance. The influence on compressive strength: PC-100>SPT>A97BS. The absolute value of zeta potential: A97BS> SPT>PC-100; In general, SPT and A97BS superplasticizer have better compatibility with dehydration phase. [ABSTRACT FROM AUTHOR] |
