Vysokohodnotný beton pro předepjaté nosníky.
[High-performance concrete for prestressed beams.]
Internal code: 04/20-09-2019_P ; 2019
Technical parameters: Receptura vysokopevnostního betonu je CEM I 42,5 R-650, Struska-60, Vápenec-15, Metaver I -75, Glenium 300- 17, Voda- 165, 0/4 Lípa -400, 4/8 Litice- 600 (složení - kg/m3). Základní mechanické vlastnosti stanovené laboratorními zkouškami jsou Pevnost v tlaku – krychelná (28 dnů)-106,2 [MPa], Pevnost v tlaku – krychelná (1 den) - 65,2 [MPa], Pevnost v tlaku – hranol (28 dnů)- 99,1 [MPa], Modul pružnosti – statický (hranol) - 41,0 [GPa].
Economic parameters: Mezi hlavní ekonomické aspekty patří zejména posílení konkurenceschopnosti společnosti ZPSV ve středoevropském měřítku. kdy získané znalosti ze specifik technologie výroby umožnily zvýšit efektivitu (cca o 10 procent) a snížit časovou náročnost. Dochází k úspoře času a nákladů ve srovnání s běžnou výrobou. Předpokládá se také zvýšení tržeb, které je obtížné predikovat s ohledem na unikátnost výrobku.
