app01-11102	Kafková, Eliška; Macháček, Jan; Kabíčková, Věra; Vlach, Tomáš	A study of the behavior of samples of high-performance concrete shells with filled core exposed to compression	2025	5	.pdf	application/pdf	2443	150	58	Plain concrete shells, as expected, were fractured completely due to the fragility of the material as there is no reinforcement. Polypropylene fibers had a negative impact toward mechanical prop- erties as they are smooth and thin and caused only the weakening of the shell structure accordingly to the lower compressive strength in comparison with plain concrete shell.	cache/app01-11102.pdf	txt/app01-11102.txt
