Bauspot Flas (GGBS)

Bauspot-Flas is GGBS fly ash (class A, NF EN 206/CN) 

It is a recyclable residue (GGBS) from granulated blast furnace slag transformed with a next generation vertical mill, used in various applications such as building industry to replace cement (see here). It is also excellent for stabilizing soils due to its high content of silicon, clay and calcium. Its lesser known use is as a soil improver for crops due to its alkalizing (for measuring pH see here) property when soils present conditions of high acidity due to various reasons (see here).

Chemical modulus (CaO + MgO)/SiO2 : > 1,25 (≥1.2: class A according to NF EN 206-1/CN)
