CONCRETE CONTAINING SUPERPLASTICISER AND PALYGORSKITE

摘要

Concept for a self-compacting, self-levelling High Performance Concrete by addition of 2-10 % palygorskite with an aspect ratio (length:diameter) of more than 35. The addition of palygorskite in combination with a superplasticiser lends itself to control of the ratio between viscosity and yield strength of the fresh concrete. Good visco-elastic properties, which assure high filling capacity, good flow properties and stability of the microstructure are obtained through this concept. Concrete produced in accordance with this invention is particularly characterised by its self-compacting properties, its filling capacity and its high stability during pumping even at high pumping pressures of 100 to 200 bars.
