DOI: 10.1016/j.cemconcomp.2019.103369
Abstract: Abstract As the most effective superplasticizer, the comb-like PCE polymers also severely retard early cement hydration and hence decelerate early strength growth of concrete, which is undesired in some applications. In this study, a series… read more here.
