PROPERTIES OF HYDRAULIC BINDER PREPARED FROM METAKAOLIN, ANHYDRITE AND LIME

Popis výsledku v původním jazyce

The paper deals with the property verification of the newly designed hydraulic binder based on metakaolin,anhydrite and lime. Two types of mixtures were prepared, and the influence of the preparation method wasobserved. The resulting mechanical properties of the hardened binder in the horizon of up to 90 days weremonitored. The change in composition over time was further studied on all hardened binder usingX-ray diffraction analysis. In addition, the porosity of the hardened binder was determined for 90-day samplesand scanning electron microscope images were taken. It was found that after 90 days the hardened bindersreached the strengths comparable to hardened Portland cement and were in the range of 40 – 61 MPa.No decrease in strength was noted over time. The main crystalline phase of the hardened binder was ettringite,which is formed at the beginning of the hydration process. With increasing time its amount remained constantor decreased slightly.
