Investigation of the effect of Daz shrub (Nannorrhops ritchiana) on concrete engineering characteristics made of Iranshahr Damn river sediments and its use in Reinforcement of structures against earthquakes

Earthquake is one of the most important natural disasters that to date it is not possible to accurately predict the time and place, for this reason, the best way to deal with this accident is to Reinforcement of structures using new methods, especially in the field of concrete against earthquakes. In case of its occurrence, the loss of life and property will be minimized. In this regard, the purpose of this study is to Investigation of the effect of Daz shrub (Nannorrhops ritchiana) o on concrete engineering characteristics made of Iranshahr Daman river sediments and its use in Reinforcement of structures against earthquakes. In this study, 15 sediment samples were collected from Daman river sediments to prepare concrete. There are shrubs called Daz along the river, and the leaves of this Daz shrub were used to improve the strength of concrete. For this purpose, a comparison between single-stranded, double-stranded and three-stranded leaves in concrete was used. The results showed that the effect of concrete strength varied by changing the number of sheets from one string to three strings. Also, an increase in concrete strength was observed by the Brazilian test. The Daz shrub double-stranded of leaf of 10.1 MPa, the single-stranded 9.5 MPa, and a sample of cylindrical concrete consisting of Daz shrub three-stranded the lowest strength of 5.1 MPa. The results showed that the highest strength is related to concrete made of double-stranded leaves.
