Two options of self-curing of High Performance Concrete

Popis výsledku v původním jazyce

. In this paper are investigated the effect of internal curing on mechanical properties of High performance concrete. The cement matrix of HPC is very dense and it is very difficult to deliver the curing water in the cement matrix. Two different materials in different dosages were selected to examine the internal curing. Chrysoplast Alpha 117 was selected as the first, and it was added 0.2% 0.4% 0.6% and 0.8% by weight of cement. This additive should allow physicochemical binding of a larger portion of the mixing water and then release it slowly for better hydration without negative effects on the products. Pre-soaked slag of 0/4 mm was tested as another source of water for internal curing. The slag was also dosed in 10%, 15%, 20% and 30% volume of the sand with the fraction 0/4 mm. The slag can then contribute to synergy with the binder composition as is the case with terrnary binders. Referential high performance concrete was a high-dose cement that consumes a large amount of water for hydration. The water/cement ratio was 0.2. Metakaolin was added to improve the properties of fresh and hardened high performance concrete.
