About the Book

Niniejsze badania opisują eksperymentalne badanie wlaściwości betonu wzmocnionego kompozytami z wlókien z kiści babki lancetowatej (PBF). Proporcje mieszanki 1:1,5:3 z czterema różnymi frakcjami PBF, a mianowicie: 0,00%, 0,25%, 0,50% i 0,75% wagowo cementu i trzema różnymi stosunkami wodno-cementowymi wynoszącymi 0,45, 0,50 i 0,55. Dla wszystkich mieszanek zastosowano wspólczynnik ksztaltu 100. Odlano 100 kostek o wymiarach 150 mm x 150 mm x 150 mm i 100 cylindrów o średnicy 100 mm i wysokości 200 mm. Przeprowadzone testy obejmowaly gęstośc, wytrzymalośc na ściskanie, wytrzymalośc na rozciąganie przy rozlupywaniu i ciągliwośc. Gęstośc próbki kontrolnej wynosila 2635 kg/m3. Gęstośc zmniejszyla się o 2,28% po dodaniu 0,75% zawartości wlókien. Ogólnie rzecz biorąc, dodanie wlókien niekorzystnie wplynęlo na gęstośc. Można to przypisac faktowi, że wlókno, które ma mniejszą wagę, zastąpilo matrycę cementową betonu, stąd mniejsza gęstośc. Podobny trend odnotowano w przypadku wytrzymalości na ściskanie. Próbka kontrolna odnotowala najwyższą wytrzymalośc na ściskanie wynoszącą okolo 41,08 MPa wśród betonów wzmocnionych wlóknami. Jednakże dodatek wlókien poprawia wytrzymalośc na rozciąganie przy rozlupywaniu. Wytrzymalośc na rozciąganie próbki kontrolnej wynosila 3,21 MPa.
