Abstract

The Mixture Design Approach was adopted in this report to formulate the correlation between the cementitious material components and material rheological properties (static yield stress, dynamic yield stress) and identify the optimal material composition to get a balance between high cementitious material static yield stress and low dynamic yield stress. Cement, sand, fly ash, water and silica fume were blended to form the test materials according to mixture design and the responses (static yield stress, dynamic yield stress) were logged by the Viskomat. Two non-linear mathematic models for responses were experimentally validated based on the ANOVA (Analysis of Variance) analysis. The results indicated that the optimal replacement of supplementary cementitious materials can be determined according to static yield stress and dynamic yield stress based on the ternary components. The Mixture Design Approach is then proven to be an effective method of optimizing the cementitious materials used in 3D cementitious material printing (3DCMP) application.
