Direct Shear Testing

Generally most of Tewang Rangkang area, Tewang Sangalang Garing District, Katingan Regency of Central Kalimantan Province is covered by clay soil with considerable development (high plasticity), the volume will change (expand) when the water content increases (changes). The volume will increase in wet conditions and will shrink when in dry conditions. It is this trait that causes damage to the construction of buildings. The purpose of this study is to know the addition of limestone to the strong value of shear and the carrying capacity of clay soil. This test was done by mixing limestone with soil in a mixture variation of 0%, 5%, 7.5%, 10%, 12.5%. Based on the results of direct shear testing against the strong value of shear and carrying capacity in the original soil obtained a strong value of shear (τ) = 0.184 kg / cm2, qult = 3.36 kg / cm2, after the addition of limestone 12.5% curing 7 days obtained strong shear value (τ) = 0.219 kg / cm2, qult = 26.04 kg / cm2, so that with the addition of limestone gives an influence on the increase in the strong value of shear and the carrying capacity of clay soil.

The flow properties were determined for two groups of food powders used in industry: cereal powders and non-starch powders. Materials were different in mean sizes of particles d* ranging from 0.033&nbsp;mm for potato flour to 4.449&nbsp;mm for oatmeal. Experiments were performed in 60&nbsp;mm in diameter direct shear tester (Jenike shear tester) for four values of consolidating stress <sub>r</sub>: 30, 60, 80 and 100 kPa. The highest values of flow function (FF) and the widest range of its variability (ranging from 0.5 kPa to 35 kPa) were found in the case of pearl barley groats. For the non-starch powders values of FF were more stable and did not exceed a limit characteristic for easy flowing materials. The highest values of FF in the group of the non-starch materials were obtained for icing sugar (from 19 kPa to 24 kPa) while the lowest found were values of FF for salt (from 3 kPa to 7 kPa). Powdered milk and potato flour showed the widest variability of FF values within the non-starch materials.
