The regulation rules of rheological properties and mechanical properties of fly ash/PVC composite were studied.The influences of plasticizer and fly ash on rheological properties and shear viscosities of the composite,as well as the relationship between the amount of plasticizer and the mechanical properties of the composite were investigated,and the optimum conditions of preparation of fly ash/PVC composite were confirmed.The rheological property of fly ash/PVC system was closely related to the addition of...
