Scotch broom, however, is much more widespread in King County and thus not required for control. These cookies ensure basic functionalities and security features of the website, anonymously. Scotch Broom Spanish and Scotch brooms are close relatives and often are found growing together. It was concluded that the quality of composite materials is more influenced by the quality of the placement than by fiber treatment.Necessary cookies are absolutely essential for the website to function properly. The results obtained on concrete were compared with those obtained on the mortar. Compressive and flexural strengths were determined on cement mortars. Hardened concrete was tested for compressive and flexural strength and dynamic modulus of elasticity. The properties of the fresh mix were determined using the flow method. The quality and mechanical properties of the cellulose fibers depend on the geographical and climatic conditions and the fiber extraction procedures so the aim of this study was to evaluate the influence of different chemical pre-treatments of the fibers on the mechanical properties of the concrete. The fibers were obtained by maceration of Spanish broom in solutions of 8%, 10%, and 15% NaOH. The mortar is reinforced with fibers of the same length and quantity as the concrete. Four mortar mixtures were also made: standard mortar and 3 fiber-reinforced mortars. Cement CEM I 42.5R, crushed limestone aggregate (D = 16 mm), and tap water were used for all the mixtures and in equal quantities. Four mixtures were made: a reference mixture and three mixtures reinforced with 3 cm long fibers, in the amount of 0.5% of the total volume. In this work, Spanish broom fibers were used for the first time to reinforce concrete. One such plant is the Spanish broom, a typical shrub of the Mediterranean region. Building materials based on renewable resources such as plant fibers are increasingly needed, especially if the plant is local and easily accessible. Scotch broom, French broom, Spanish broom, shiny geranium, yellow star thistle, knapweed, yellow water primrose and parrots feather are among the other.
