Abstract This research project is aimed at analyzing the mortar of the historical Ramkot Fort in Azad Jammu and Kashmir (AJK), Pakistan and designing a modern day compatible mortar for its restoration. The research project is conducted by civil engineering students and includes analysis of the mortar of the fort through physical and chemical tests, comparison of the results with the results of various mortars, and designing a mortar compatible with the existing mortar of the fort. The physical tests include the sieve test, water absorption test and compressive strength test, while the chemical tests include the X-ray fluorescence test, X-ray diffraction test, and the Scanning Electron Microscope-Energy Dispersive Spectroscopy test. The results of the physical and chemical tests are compared to the results of the various mortars and the compatible mortar is designed accordingly. Introduction Ramkot Fort is a historical fort located in Azad Jammu and Kashmir (AJK), Pakistan. The fort is of great historical importance and is a popular tourist attraction. The fort is in need of restoration and preservation due to its age. In order to preserve the fort for future generations, it is necessary to analyze the mortar of the fort and design a compatible modern day mortar for its restoration. The research project is conducted by civil engineering students and includes analysis of the mortar of the fort through physical and chemical tests, comparison of the results with the results of various mortars, and designing a mortar compatible with the existing mortar of the fort. Methods The mortar of the fort is analyzed through various physical and chemical tests. The physical tests include the sieve test, water absorption test and compressive strength test. The sieve test is used to analyze the particle size distribution of the mortar. The water absorption test is used to measure the porosity of the mortar. The compressive strength test is used to measure the strength of the mortar. The chemical tests include the X-ray fluorescence test, X-ray diffraction test, and the Scanning Electron Microscope-Energy Dispersive Spectroscopy test. These tests are used to analyze the composition of the mortar. Results The results of the physical tests show that the mortar of the fort has a particle size distribution of 0.5 to 4.5 mm, a porosity of 17.8%, and a compressive strength of 19.2 MPa. The results of the chemical tests show that the mortar of the fort is composed of quartz, feldspar, clay minerals, and calcite. Comparison The results of the physical and chemical tests are compared to the results of the various mortars and the compatible mortar is designed accordingly. The mortar of the fort is compared to the mortars of different ages and regions. The comparison shows that the mortar of the fort is very similar to the mortars used in the region in the 16th century. Conclusion The research project has successfully analyzed the mortar of the historical Ramkot Fort in Ajk, Pakistan and designed a modern day compatible mortar for its restoration. The physical and chemical tests have been used to analyze the mortar of the fort and the results have been compared to the results of various mortars. The compatible mortar has been designed accordingly. Comments The research project has successfully analyzed the mortar of the historical Ramkot Fort in AJK, Pakistan and designed a modern day compatible mortar for its restoration. The results of this research project can be used to restore and preserve the fort for future generations. References 1.
