Perspective of concrete with portland composite cement CEM II/C-M (S-LL)
Języki publikacji
Abstrakty
W 2021 roku cementownie na Słowacji rozpoczęły produkcję cementu portlandzkiego wieloskładnikowego typu CEM II/C-M zgodnie z normą STN EN 197-5. Głównym celem jest zmniejszenie śladu węglowego przez produkcję cementu o mniejszej zawartości klinkieru. Zastosowanie tego cementu jest obecnie ograniczone, ponieważ normy dotyczące wyrobów budowlanych dopuszczają stosowanie wyłącznie rodzajów cementu zgodnych z normą STN EN 197-1. Dla rodzajów cementów spełniających wymagania STN EN 197-5 nie jest wskazana ogólna przydatność ich stosowania w betonie zgodnie z STN EN 206+A2. Możliwość stosowania poszczególnych rodzajów cementu wyłącznie zgodnie z normą STN EN 197-1 dla klas ekspozycji XC, XF, XD i XA jest określona w Załączniku krajowym STN EN 206+A2/NA. Należy zatem wykazać przydatność zastosowania nowego betonu cementowego. Celem przeprowadzonych badań było wyjaśnienie możliwości wykorzystania CEM II/C-M (S-LL) w praktyce. W artykule przedstawiono wyniki projektu badawczego, którego celem było sprawdzenie przydatności CEM II/C-M (S-LL) do stosowania w betonie zgodnie z wymaganiami normy STN EN 206+A2.
In 2021, cement plants in Slovakia started production of Portland composite cement of CEM II/C-M type according to STN EN 197-5. The main objective is to reduce the carbon footprint in the production of types of cement characterized by lower clinker content. The application of this cement is currently limited because the construction product standards only accept the use of types of cement according to STN EN 197-1. For types of cement meeting the STN EN 197-5 requirements, the general suitability of their use in concrete according to STN EN 206+A2 is not indicated. The applicability of individual types of cement only according to STN EN 197-1 for exposure classes XC, XF, XD, and XA is specified in the National Annex (STN EN 206+A2/NA). The suitability of the use of new cement concrete must therefore be demonstrated. The aim of the research carried out was to clarify the potential of using CEM II/C-M (S-LL) in practice. This article presents the results of a research project aimed at verifying the suitability of CEM II/CM (S-LL) for use in concrete following the requirements of STN EN 206+A2.
