الملخص EN

An evaluation of the limestone Rocks, in the Eoin Al-Shujage area, governorate of Najaf ,as building Materials was done in this research ten stations covering an area of (16) km2 were studied.

The research included several field, laboratory, and office aspects .in the field part , information about the study area were collected ,also the collection of samples were done .the samples were analyzed in the laboratory in order to study the physical, Engineering , and mineralogical properties of the rocks.

The Physical tests showed that the bulk density ranges between (1.81-2.45) gm / cm 3, while the value of the porosity ranges between (4.82-22.29) % ,The water absorption of the limestone rocks value range between (2.66-9.45) % The value of the specific weight of the Limestone was between (2.11- 2.65).

The engineering tests, which included uniaxial compressive test , and mechanical abrasion test , and the modulus of rupture test, the results showed that the uniaxial compressive values when the samples are dry ranges between (65.91-12.44) GPa , while the values of rocks limestone in saturated case ranged between (5.71-52.85) GPa .

The test of the mechanical abrasion of the limestone rocks between (20.4-59.6%), while the the modulus of rupture value ranged between (6.9- 2.8) GPa, Also made mineralogical tests showed.
