动态模式流变仪被用来研究水泥和纯硅酸三钙浆料的结构的演变，从混合到设置，甚至设置后，连同负责的糊的机械性能的力的性质。在混合结束后的最初几分钟内，一种特殊的混合器类型的工具被用来研究神学，这是经典工具无法达到的。两种浆料具有相同的行为。结果发现，主要的演变的糊状物的结构发生在第一分钟的混合结束后，而没有变化的interparticle部队设置，甚至几个小时后。由维卡针定义的凝固与糊剂内的力或结构转变的性质的任何特定变化无关。(C)2001爱思唯尔科技有限公司版权所有。
Dynamic mode rheometry was used to study the evolution of the structure of cement and pure tricalcium silicate pastes from mixing up to setting and even after setting, together with the nature of the forces responsible for the mechanical properties of the pastes. A special mixer-type tool was used to study theology during the very first minutes following the end of mixing, which are out of reach with classical tools. Both kinds of pastes have the same behavior. It was found that the main evolution of the structure of the pastes occurs during the very first minutes following the end of mixing, while there is no change in interparticular forces up to setting and even a few hours later. Setting, as defined by the Vicat needle, is not related to any particular change of the nature of the forces or structural transition within the paste. (C) 2001 Elsevier Science Ltd.
