Topic: Correlation of Shear Strength, Compressive Strength and Physical Properties with Angularity of Granular Particles.
Abstract: This study concerns to the correlation of granular particle and their properties and strength. Sand is used as samples the granular particle consisting of sea sand and river sand; obtain from three different locations, Papar, Kota Kinabalu and Tuaran. The testing will determine whether the angularity of sand particle shape is related to the strength of the soil itself. The testing of the sample consists to two parts which is material testing and concrete testing. While material testing is divided to two sub-parts which is physical testing and mechanical testing. The material testing is includes compaction, sieve analysis and direct shear box, and the concrete testing is consisting of compressive strength test. By using microscope, sample from Papar was known as sub-rounded with low sphericity, sample from Kota Kinabalu relatively very angular with medium sphericity and sample from Tuaran is relatively angular also with medium sphericity. Compaction test result showed that samples from Kota Kinabalu have the highest optimum density with 3518 Kg/m3 followed by sample from Papar with 3504 Kg/m3 and sample from Tuaran with only 3287 Kg/m3. While, compressive strength tested to the concrete cube shows that Sample from Kota Kinabalu and Tuaran having the highest shear strength which is 3.472 KPa and sample from Papar is only 3.444 KPa. This test is supporting the theory of the higher sphericity will affect the strength of soil structure. In future, the study of sand in Sabah can be explored more, covering several other tests.
