| Abstract | ||
| The point load test is used as a quick and inexpensive means of obtaining rock strength indexes when logging core samples in either a field or laboratory setting. In order to estimate the Uniaxial compressive strength, indirect tensile strength (Brazilian and 4-point bending)of the rocks, index to strength conversion factors are used to involve three types of the most popular sedimentary rocks in Mosul city, which are limestone, sandstone and gypsum in both dry and wet conditions. The results showed that a conversion factors,(14.55,15.9) can be used to estimate compressive strength for both limestone and gypsum rocks in dry and wet conditions respectively. The study also found that conversion factors,(1.4,2.6) are applied in dry condition for the three rocks in Brazilian and Bending tests. | ||
