Abstract: A new perspective on the hydration process of graphene oxide (GO)/cement composites is provided in this paper. The quantitative evaluation of GO on the hydration of four minerals and the dissolution sequence of the four ...

Abstract: To improve the understanding of underlying mechanism concerning the change in concrete properties after pumping, the effect of pressure (from atmospheric pressure to 15 MPa) on the time-dependent rheological properties ...

Abstract: Effects of polycarboxylate ethers (PCEs) with different charge densities on the time-dependent rheological property (yield stress) were systematically investigated by correlating the charge density of PCE with its adsorption ...

Abstract: The aim of this study was to link the molecular weight (MW) of polycarboxylate superplasticizer (PCE) with the performance of cementitious system for the purpose of developing new products; PCE synthesized by copolymerization ...

Abstract: Polycarboxylate ether (PCE) of different charge densities has been synthesized via free radical polymerization. The molecular structure is characterized by gel permeation chromatography (GPC) and proton nuclear magnetic ...

Abstract: Polycarboxylate (PCE) superplasticizers greatly affect the rheological properties of cementitious materials. Yet, the systematical influence of the PCE structure parameter on the rheological properties of cement paste is ...
