Možnosti využití tepelně aktivovaných jílů jako částečné náhrady cementu

Název projektu anglicky
Alternatives of thermally activated lower grade clays as a partial cement replacement
Anotace anglicky
The most common representative of clay materials applicable as supplementary cementitious material (SCM) is indisputably metakaolin, more precisely thermally activated kaolinite. It is well-known, that its application leads to improvement of overall performance of mortar and concrete, and alike to other SCM representatives, there is a great ecological benefit in the cement consumption decrease. Unfortunately, wide application of metakaolin is limited due to the high price caused by necessity of noble raw-material. This project is focused on study of alternative clays, which can be thermally activated as well. Such clays contain varying clay minerals, carbonates and impurities; therefore, they are more available. As their quality is lower, it is necessary to more thoroughly optimize their thermal activation. The main aim of the project is to find out relationship between clays composition, calcination regime and pozzolanic activity. Afterwards to use activated clays in blended low-cement composites, and through the view of wide range of properties assess their practical usage.
