Abstract The idea behind the present work is to assess robustness of fresh cement-based materials (i.e. their ability to display the same properties when submitted to variations in the way they are produced) from a generic and analytical point of view. First, analytical models from literature relating components proportions and yield stress are combined into a multi-scale and physical approach and compared to our experimental yield stress measurements. In the second part, the derivation of these analytical relationships is used to assess robustness as a function of components proportions, which allows for the most sensitive variations to be mapped onto component dosage from a yield stress point of view. In the case of fluid concretes, this approach showcases the interest of working at slightly higher water content and slightly lower aggregates fraction along with benefits of viscosity modifying agents / plasticizers combination.

水泥基材料的坚固性：从剂量变化到屈服应力波动

摘要 当前工作背后的想法是从通用和分析的角度评估新鲜水泥基材料的稳健性（即，当它们的生产方式发生变化时，它们显示出相同特性的能力）。首先，将与组件比例和屈服应力相关的文献中的分析模型组合成多尺度和物理方法，并与我们的实验屈服应力测量值进行比较。在第二部分，这些分析关系的推导用于评估作为组件比例函数的稳健性，这允许从屈服应力的角度将最敏感的变化映射到组件剂量上。在流体混凝土的情况下，
