![]() ![]() ▸ It adds the mixing water and lime and malaxant well the mixture. ▸ The plaster is added, while blending it well with the sand and fibers ▸ We are mixing first of all the Sand and fibers to sec The mixing is carried out in the following way: ▸ They add 6 % limes air as retarding of setting time.Īfter the preparation of fibers of date palm, we respect the recommendations of KRIKER, for this, the fibers used are treated in the water, then dried in the free area. ▸ The report of S/P is set to the value 0,5 The determination of the composition of mortar plaster reinforced with fibers of date palm, we used the same composition with the classic mortar, so we take the following composition: Table au 5: Essential Properties of plasterįinesse following the method of Blaine in cm2/g In addition it does not affect these mechanical properties.Ī chemical analysis of the lime used was performed using the method of diffractometer by X-rays in the lab.physics at the University of Laghouat, the results of this technique are presented on the diffractogramme below (Table 2). LimeĪir lime as a retardant of setting time of the plaster was used, because it decreases the solubility of the latter and allows to increase the time of employment. The used mixing water is the public drinking water of the network of the city of Ghardaïa. The physical properties of sand dunes used are represented in table 1 Mixing water In our study we used the sand dunes of GUERRARA (GHARDAIA). The materials used are those available at the local level: Sand dunes used and the study of the sustainability of this material. The improvement of certain physical and mechanical properties of the Mortar plaster through its strengthening with the fibers of the date palm.Study of composition of a pate of plaster pure and a mortar of plaster to basis of dune sand.The study itself offers two essential objectives and which are: and integrate in a rational way in the field of construction. The objective of this work is to make our contribution to the enhancement of local materials, such as gypsum, dune sand and the fibers of the date palm. Where we are looking at the impact of the rate and length of the fibers of date palm on the characteristics of mortar plaster, in the short and in the long term. In our study, we will examine the effect of the addition of fibers of palm trees date palm to the physical and mechanical properties of the Mortar plaster. The major assumption that the fibers allow the judgment of the cracking mechanism, delaying the start of the crack and the controlling once it appears. The incorporation of the fibers of date palm in the mortar of plaster, is carried out in order to improve the tensile strength and decrease its fragility. Algeria has unlimited sources of vegetable fibers (of Palm, Alfa Abaca, hemp, Cotton.), but their use in the construction of the almost non-existent field. The use of vegetable fibers in the reinforcement of building materials to improve certain properties, it is the most used technology currently, because these results and to expand the use of eco-materials. Among these materials, which can be exploited, and that we will consider, plaster, sand dune, and the fibers of the Palm. The Algeria, especially the South, is rich in natural materials, which can then be used directly in the construction field he must study their properties in order to extend their use. Current materials research is concerned with the development of new composites of building materials, with the aim of improving the mechanical, physical and durability properties of these materials. This is primarily due to the gradual replacement of petrochemicals with renewable resources, such as the efficient use of local materials. The Kyoto Protocol on global climate change has accelerated the transition to a sustainable and more environmentally friendly economy. ![]()
