Reactive silicate binder stabilization: Saint GobainRecent Research Landscape

Sulfate attack leads to thaumasite formation which causes catastrophic loss of structural integrity in hydraulic cements. Controlling the reactive silica source and binder stoichiometry prevents this chemical degradation to ensure long-term infrastructure durability.

What technical problems is Saint Gobain addressing in Reactive silicate binder stabilization?

Thaumasite induced expansion and instability

(4)evidences

The formation of thaumasite in silicate binders causes significant structural swelling and mechanical degradation. Preventing this specific mineralogical failure mode ensures the dimensional stability and durability of cementitious articles.

Alkaline chemical degradation

(3)evidences

Cementitious binders and reinforcing additives suffer from structural breakdown when exposed to harsh alkaline environments or strong acids. Preventing this degradation ensures the long-term integrity of manufactured articles.
