| Abstract | ||||
| Being the inherent attributes of carbonate rocks, the petrographic characteristics such as mineral composition, texture, detrital materials, porosity and microstructures are very important factors that influence their compressive strength. Different in situ and laboratory tests were conducted to investigate petrographic characteristics and compressive strength of the Eocene and Miocene carbonate rocks of New Cairo City. The results show that the uniaxial compressive strength of carbonate rocks increase with decrease allochem fragments, idiotopic crystals, detrital materials and porosity. On the other hand, their uniaxial compressive strength increase with increase cemented materials, hypidiotopic crystals within the rock. The relationships of calcite cemented materials crystal size with rock strength indicated that; the fine crystals have best relations with rock strength parameters than the large crystals. | ||||
