High volume of fine particles in scc is usually achieved by using mineral additives pozzolanic and non-pozzolanic, since an increase in cement content in concrete mixture leads to a significant rise in material cost and sometimes can have negative effects on concrete properties e.Increased thermal stresses and shrinkage, etc.

Ultra High Performance Concrete In A Ction

Concrete with such a high compressive strength has a wb ratio below 0.To create a workable mix, chemical or mineral additives must be used to control the hydration process.Whereas fly ash and ggbs are seen as replacements for ordinary cement, the silica fume, metakolin or ultra-fine fly ash are seen as performance-enhancing additives.
