Characteristics
ZeoCem Micro - is fine ground natural zeolite designed for the building industry. More than 85 % is made by zeolite mineral called clinoptilolit. It is used as a partial substitute of cement for its pozzolan characteristics. In cement mixture, it increases the level of aggressive substances resistance (sulphate and carbonate solutions). The level of sealing abilities of hardened concrete is also increased. ZeoCem Micro zeolite addition has an inhibitive effect on alkali-silica reaction in concrete. It contains min 90% of volume under 200 micrometers.
Use
- high value concretes
- concretes with requirements on high resistibility on aggressive environment
- concretes with high requirements on waterproofness
