In order to enable the separate adjustment of the liquidation compactibility and formwork erection stability of pavement concrete, the effects of four kinds of air-entraining agent and Welan gum on fluidity, air content and rheological properties of cement mortar were studied.The results showed that: air-entraining cement mortar can be regarded as Bingham body.Entraining bubbles can regulate the flow of the slurry.When fluidity small, air bubbles can reduce the yield stress of the slurry, improve mobility;contrary, air bubbles on the fluidity of the slurry to produce certain degree of inhibition.Air content of cement mortar with different flow patterns are increase with air-entraining agent content increases, but have different performance.Low air-entraining agent dosage, air content of high flowing mortar is larger than the low flow state mortar;entraining agent at high dosage, the results of the opposite.As the proportion of AEA increases, the plastic viscosity of the air-entraining cement mortar gradually falls, with the rate depending on the AEA.With the addition of Welan gum, the plastic viscosity is dependent on the air content, in that an increase in the air content causes the plastic viscosity to decrease;the yield stress values of A, B, C, D were gradually increased, air-entraining cement mortar fluidity decreased.There are negative correlation exists among flow of air-entraining cement mortar, Welan gum content and yield stress values.Air-entraining, foam stability and rheological properties of the mortar together decide the air content of cement mortar.Air content of A and D mortar with the increase of Welan gum first increases then decreases, while B and C mortar gradually reduced.With the addition of Welan gum, the plastic viscosity of the air-entraining cement mortar D is significantly lower than that of the other types.AEA D combined with Welan gum can minimize the plastic viscosity and increase the yield stress to some extent.
