| Original Abstract: | The contribution presents results from destructive and non-destructive experimental tests on specimens from lightweight concrete with fibres, which are compared with tests results on specimens from lightweight concrete without fibres. As an aggregate an inland-made porous aggregates Liapor and heavy-weight aggregates with maximal grains of 8 mm was used. According to CSN P ENV 206 the reference concrete conform to the grade of concrete LC 45/50 with density 1800 kg/m3. As a dispersed reinforcement a polypropylene fibres Forta Ferro of 54 mm length and tensile strength of 620 - 758 MPa was used. |
| Czech abstract: | V článku jsou uvedeny výsledky destruktivních a nedestruktivních zkoušek provedených na vzorcích z lehkého vláknobetonu, které jsou porovnávány s výsledky zkoušek na vzorcích z lehkého betonu bez vláken. Jako plnivo do betonu bylo použito lehké pórovité kamenivo Liapor a hutné kamenivo s maximální velikostí zrna 8 mm. V souladu s ČSN O ENV 206 byl referenční beton zařazen do třídy betonu LC 45/50 s objemovou hmotností 1800 kg/m3. Jako rozptýlená výztuž byla použita polypropylenová vlákna Forta Ferro délky 54 mm a pevností v tahu 620 - 758 MPa. |
