One of the most commonly known test for rock mechanics is unconfined compressive strength (UCS) test. Unconfined compressive strength test is a test used to determine the strength of rock under one stress component (uniaxial) by using a compression Machine to push rock samples are cylindrical, beam, or a prism up to the rock sample failure . will provide mechanical rock properties described as unconfined compressive strength (&#963;c), Young’s modulus (E), Poisson's ratio (&#965;), and stress – strain curve. One of the factors that influence the results of unconfined compressive strength is loading rate . The purpose of this research is to study the effect of loading rate on the unconfined compressive strength of limestone samples and sandstone samples. In this research, 6 units of limestone samples and 6 units of sandstone samples are cylindrical were tested with unconfined compressive strength test at <br /> <br /> <br /> loading rate based on range from 100 kgf / min (+ 0.01 MPa /s) up to 600 kgf/min (+ 0:06 MPa / s). Based on the results of this research , and regression analysis for unconfined compressive strength test, the limestone samples in the test gave an effect relationship of increasing loading rate followed by increasing of unconfined compressive strength (&#963;c ), but different with sandstone samples that did not give a definite influence of loading rate on unconfined compressive <br /> <br /> <br /> strength (&#963;c). For Young's Modulus (E), Poisson ratio (&#965;) and stress - strain curves on limestone and sandstone samples were also not able to showed the influence of loading rate significantly.
