building materials for roads and civil engineering from mixtures of schlackengranulaten and flugaschen coal-fired with building materials herkoemmlicher type

摘要

The material mixt is made up from suitably graded coal fired power station waste such as clinker., fly ash together with binders and chemical setting delay and frost protection agents. The above materials are more cheaply available in highly industrial areas than natural materials, their use also solves a disposal problem for these materials. The building material is used in road and underground works construction.
