The Effect of Metakaolin and Silica Fume on the Properties of Lightweight Self Consolidating Concrete

This paper is concerned with the development of lightweight self-consolidating concrete, especially with the comparison of the effect of metakaolin and that of silica fume on the properties of this concrete. The use of metakaolin for improving the durability and for achieving better physico-mechanical properties of concrete is relatively new approach in concrete technology. The experimental works which are described in this paper are used for the manufacture of lightweight self-consolidating concrete of different fractions of the expanded clay lightweight aggregate Liapor with different fractions of normal weight aggregate. The metakaolin used of Czech production.
