The Natural Fibres of the Spanish Broom in the Cement Mortar : Undergraduate Thesis

Danas se sve više vodi briga o zaštiti okoliša i zahtjevima za ekološki prihvatljivije i energetski učinkovitije materijale. Tako se i u građevinarstvu nastoje sve više upotrebljavati prirodna vlakna koja su lokalno dostupna, jeftinija i ekološki prihvatljivija. U ovom radu korištena su vlakna brnistre dobivena maceracijom u 5% otopini NaOH, koja služe kao ojačanja u cementnom mortu. Dobiveni rezultati uspoređeni su s jednako tretiranim vlaknima, ali godinu ranije berbe.Today, there is more and more interest in protection of the environment and in requirements for environmentally friendly and energy efficient materials. So, in civil engineering there is also endeavor to use more of the natural fibres that are locally available, cheaper and environmentally friendly. The Spanish broom fibres that have been used in this study were obtained by maceration in 5% solution of the NaOH, and those are used as reinforcements in the cement mortar. Obtained results are compared with fibres that are treated equaly, but harvested a year before
