聚合物和新拌混凝土性能研究进展（英文）

Recent Advances on Polymers and Fresh Concrete Properties

通过对颗粒/颗粒和颗粒/液相之间相互作用进行理论和微观力学研究,首先提出了稳定状态下水泥净浆在简单剪切力作用下,以剪切速率和固体体积分数为参数的主要影响因素理论方程。在此框架下,对水泥混凝土工业中常用聚合物掺入后,胶凝材料浆体基本物理性能研究的最新进展进行了阐述。最后,讨论了水泥净浆流变性能和新拌混凝土性能之间的转换关系。

By going through rational and micro-mechanical arguments on particle/particle and particle/fluid interactions, we first provide here a conceptual diagram of predominant interactions within flowing cement pastes under simple shear in steady state as a function of shear rate and solid volume fraction. Within this frame, we then focus on the last four years advances in the understanding of the main changes in the underlying physics occurring when the most common polymers used in the cement construction industry are added to a cement suspension. We finally discuss the upscaling between cement paste rheology and concrete fresh properties.
