INTERRELATIONSHIP BETWEEN THE MICROFACIES CONTENT AND MECHANICAL BEHAVIOUR OF LOCKHART LIMESTONE AT SHAH ALLA DITTA, ISLAMABAD, PAKISTAN

Abstract

The study aimed to find out geo-technical properties and correlation of micro facies and mechanical properties of Lockhart limestone, in Shah Alla Ditta region. Performed couple of fields for sampling and samples that were obtained on field were further processed towards laboratory testing for carrying out different geo-technical tests, that include uniaxial compressive strength, specific gravity, Los Angeles abrasion test and water absorption or porosity test, which later on gave some particular results, through which derived certain results and deduced geo-technical properties of Lockhart Limestone and by using previous work of microfacies and correlate microfacies with mechanical properties of Lockhart limestone. Performed each and every task with proper care and attention by keeping the health and safety factor constant. From the results of Geo-Technical tests that were performed on samples acquired from Lockhart limestone tend to be good and can be used for minor Engineering purposes, and as UCS value seems to be weak so this could not handle heavy loads but can be used in the minor construction projects like Road pavements and ramping etc.
