由于新的加工技术的发展，避免了使用标准的模板，新的水泥基材料的弹性和屈服性能的兴趣最近已经增长。在没有支撑的情况下，材料成型仅依赖于新材料的机械性能。在此框架内，本文的重点是收集公认的知识沿着最新进展的屈服应力和弹性的新水泥基材料。在第一部分中，我们将通过这些宏观性质的物理和化学起源及其演变。在第二部分中，我们将描述它们可以被测量的方式，而第三部分将处理它们可以被控制和调整的方式。最后，最新的模型，从混合设计和加工建模的流变测量性能预测将被描述。
The interest in the elastic and yielding properties of fresh cement-based materials has recently grown due to the development of new processing techniques, which avoid the use of standard formworks. Without support, the material shaping relies only on the mechanical properties of the fresh material. Within this frame, the point of this paper is to gather the accepted knowledge along with the most recent advances on both yield stress and elasticity of fresh cement-based materials. In the first part, we will go through the physical and chemical origin of these macroscopic properties and their evolutions. In the second part, we will describe the way they can be measured while the third part will deal with the way they can be controlled and tuned. Finally, the most recent models for both properties prediction from mix design and processing modeling from rheological measurements will be described.
