G.tecz realized blueCONCRETE for several companies worldwide. The aim of the optimization is next to the economical and ecological benefit always a little bit different: Increasing workability, increasing porosity, increasing the compressive strength of the young concrete for a faster de-molding. That's why G.tecz will find individual solutions and can develop your individual blueCONCRETE.
Reduction of cement does not automatically lead to a reduction of the early strength - Quite the contrary is possible. The early strength can be held or even improved.
The diagrams above and below are showing, that within the same water/cement ratio, the compressive strength of the concrete can be increased dramatically while reducing the cement up to 20%.
