“…From the figure, it is shows that when the velocity of P-wave increased automatically the strength also increased. It means that the faster velocity could grow as the strength of sandstone increased [18,21]. The data that plotted on the graph shows that velocity of P-wave for sandstones ranging from 1000 m/s to 4000 m/s.…”

Rock characterization of tropical Kenny Hill weathered sandstone have been an effort to be explored by using non-disruptive testing of pundit and resistivity testing to undertake sustainability issues and providing technical approach in exploration of weak rock materials solving. The purpose of this research is to determine the relationship between resistivity and uniaxial compressive strength of the most problematic rock type in Malaysia, namely Kenny Hill weathered sedimentary rocks, more usually referred to as sandstone. According to earlier study, sandstone has degraded in quality and has a tendency to disintegrate due to the tropical climate. Sandstone has a higher strength feature as compared to shale from Bandar Nusa Rhu, Shah Alam. Series of uniaxial compression were carried out to obtain the strength for rock samples. The strength properties of weathered sandstone are studied to quantify the weathering impact to these materials. Resistivity test and Pundit test were laboratory method conducted on the rock samples for verification of the correlation between resistivity and uniaxial compression. Results from the test were analyzed and their relationship with weathering grade was established. It signifies that sandstone strength increasing with the weathering grade.

“…However, it is difficult and quite costly to evaluate the shear strength of jointed rock directly at the site [2]. Several researchers have conducted empirical relationships between mechanical behavior of rock material, such as done by [3] and [4]. Moreover, most previous studies, such as those done by [5] and [6], just conducted a physical model and numerical modelling to find the characteristic of jointed shear strength.…”

Shear Strength of jointed rock plays a significant role in the stability of rock mass structure especially if the developments plan to be constructed adjacent to this formation. However, to get the shear strength of the rock joints is quite costly and difficult to be identified directly at site. This research is conducted to establish the relationship between uniaxial compressive strength (UCS) and shear strength of jointed granitic rock. UCS parameters are quite easily identified and common practise in any construction project such as deep foundation and tunnelling. The result of uniaxial compressive strength test and direct shear test were plotted using 5 samples of cylindrical shape and 5 jointed rock samples respectively. The linear regression analysis produces meaningful correlation with R2 value of 0.8595 and a new correlation to estimate shear strength of jointed rock has been established.
