TY - JOUR A1 - Schmidt, Wolfram T1 - Mode of action of different superplasticisers JF - Concrete plant international CPI N2 - Over the course of the last decades, concrete construction has significantly changed from mass application towards sophisticated more innovative, future oriented, and performance based materials technology. Today concrete no longer consists of cement, water, and aggregates, but can be enhanced significantly by using supplementary additions and chemical admixtures. At the same time the concrete specifications are no longer limited to Young’s modulus and compressive strength, but concrete may need to be designed for a multiple of application criteria such as durability, workability, optics, fire behaviour, and many more. However at the same time, the composition of concrete has become more complex due to the higher number of mutually interacting mixture constituents. Understanding the effects of changed mixture constituents is challenging but a good understanding is the key to innovative concrete technology.
