摘要
The types and performance of admixtures, as well as their mechanisms of plasticization, characteristics of flowability, and compatibility between admixtures and cements are discussed. The determination of viscosity is important for knowing the state or physical property or fluidity of liquids and gases. The coefficient of viscosity is the physical constant representing the magnitude of the ease with which the fluid will flow. Computational rheology is used to merge phenomelogical rheology and materials science rheology together to further the understanding of the rheology of cement paste and concrete. A new type of superplasticizer that provides a reduction in drying shrinkage has been developed, whose characteristics is the reduced amount of dosage compared to ordinary shrinkage reducing admixtures. The emergence of polycarboxylic acid-based AE and high range water-reducing admixture is an indispensable element for the development of self-compacting concrete.
