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.
Compressive strength of cement plaster crack#
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. 2016 6(1): 23–29p.The Kyoto Protocol on global climate change has accelerated the transition to a sustainable and more environmentally friendly economy. Recent Trends in Civil Engineering & Technology. Standardization of Cement Mortar by Using GGBS for Plaster Work. Priyanka Sabale, Vrushali Tandulkar, Snehal Randive, et al. Keywords: Granulated blast furnace slag (GGBS), compressive strength, flexural strength, split tensile strength The tested results show that mechanical properties using material like GGBS is enhanced, and good strength is imparted to the mortar. Test results revealed that 20% GGBS replacement by weight of cement is the optimum percentage to produce the maximum increase in the strength. Cubes (70.6mmx70.6mm), beams (160mmx40mm), and cylinders (50 mm Diameter, height 100 mm) were casted to evaluate compressive strength, flexural strength, and split tensile strength at 7, 14, and 28 days respectively. The methodology which it undergoes is slump test, compressive strength, flexural strength, split tensile strength. This study investigates the feasibility of using, replacement of natural river sand with 100% crushed sand, and partial replacement of cement with optimum percentage of ground-granulated blast-furnace slag (GGBS) on site conditions with a proportioned water cement ratio for plaster work.
