Abstract To improve the workability of cement-based material with recycled powder(RP), the effect of superplasticizers on the rheological properties of RP-cement paste was investigated. Meanwhile, the adsorption behavior of superplasticizers in paste, the packing density and the viscosity of interstitial solution were analyzed to reveal the adsorption on the viscosity of paste with RP. The results show that superplasticizers has a stronger adsorption ability on the RP surfaces with the similar flow spread of paste, especially for the carboxylic-superplasticizer and sulfonic-superplasticizer. Whereas, a higher packing density and viscosity of interstitial solution can be obtained for the paste with the addition of phosphonic-superplasticsizer, which will affect the viscosity of cement paste with RP together. Due to a lower viscosity of the interstitial solutions of carboxylic-superplasticizer and sulfonic-superplasticizer, the viscosity of cement paste with a low substitution rate of RP is lower than that of paste with phosphonic-superplasticsizer. However, with a high substitution rate of 30%, the well dispersion of mix particles with the help of phosphonic-superplasticizer can result in an increased packing density, thus leading to a lower viscosity of cement paste with RP, compared to that of paste with other superplasticizers.

Key words： recycled powder superplasticizer residual viscosity viscosity of interstitial solution adsorption packing density
