This article has confirmed that mud, as one of the oldest building materials of rural architecture in Iran, has been used in various forms such as layers, clays, mortars and plasters. Despite the features that strengthen the use of this building materials in this type of architecture, there are weaknesses such as erosion resistance against moisture, low tensile strength, and it is necessary to provide solutions that can overcome the existing weaknesses while improving the mechanical features of this material building.
The existence of additives or natural fibers in the structure of these building materials, which has been noticed for a long time, is a correction in this regard. However, the current research seeks to use synthetic fibers in improving the mechanical properties of such building materials and in this regard, it is trying to evaluate the effect of polypropylene synthetic fibers on their tensile strength.
The present research is based on the laboratory method and measured the tensile strength of mud structures under the influence of polypropylene fibers in two lengths of 6 and 12 mm with different weight percentages in order to find the best weight percentage for this composition. The results showed that by using 2% polypropylene fibers with a length of 6 mm, the tensile strength of this building material can be increased up to 302% compared to the initial state; In addition, as the weight percentage of additive fibers increases from 12%, the tensile strength of the reinforced sample decreases compared to the control. The results also showed that the fiber length of 6 mm has a greater effect on improving the tensile strength of reinforced clay.
