Experimental Study on the Influence of Cement Rheology on Concrete Properties
In order to improve the quality of highway concrete construction,this paper takes section K68+942～K74+876 of Ehan Expressway as an example to carry out an experimental study on the influence of cement rheology on concrete properties.The results show that the water consumption of cement standard consistency is negatively correlated with the fluidity of concrete.The setting time of cement is negatively corre-lated with the setting speed of concrete.The longer the setting time of cement,the slower the setting speed of concrete and the longer the set-ting time.When the concrete slump is low in the general slump range of highway concrete,the slump of concrete can be derived by analyzing the flow of cement mortar,which can provide support for the subsequent construction activities.
