![]() Historically, the Spanish Gold Broom has been a part of the local flora in these areas for centuries. The plant’s natural distribution extends across the western and central parts of the Iberian Peninsula, including the mountainous regions of the Sierra Nevada and Sierra de Guadarrama. It is endemic to this region, particularly in Spain and Portugal, where it thrives in the Mediterranean climate. The Spanish Gold Broom, Cytisus pagans, traces its origins to the Iberian Peninsula in southwestern Europe. Whether you are a seasoned gardener or intrigued by the natural world, this article will serve as an engaging resource to uncover the allure of the Spanish Gold Broom and appreciate its beauty. Additionally, we will discuss the historical and cultural associations tied to the Spanish Gold Broom and its impact on various aspects of society. We will explore the origins and distribution of this plant, its growth habits, and the environmental conditions necessary for its cultivation. This article aims to provide a comprehensive overview of the Spanish Gold Broom, delving into its botanical features, cultural significance, and its popularity among gardening enthusiasts. The Spanish Gold Broom has become highly sought after by garden enthusiasts and botanical collectors worldwide, captivating them with its allure and charm. Native to the Iberian Peninsula, this perennial shrub is renowned for its vibrant golden flowers and delicate foliage. ![]() It was concluded that the quality of composite materials is more influenced by the quality of the placement than by fiber treatment.The Spanish Gold Broom, scientifically known as Cytisus pagans, is a beautiful plant that has gained significant attention for its unique characteristics and striking appearance. 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.
