ABSTRACT: Room temperature drying tests on silt slurry with free and constrained boundaries, reveal an initial phase with a significant shrinkage at full saturation. Hence, this shrinkage is linked to a mass loss of pore fluid through the external boundary. Shrinkage in the unsaturated phase is much smaller. A simultaneous porosimetry reveals a bi-modal pore size distribution with a distinct ev...
متن کاملEngineering Properties and Shrinkage Limit of Swelling Soils in Greece
The existence of specific expansive minerals in the clay soil related to the climatological conditions, seasonable variation of rainfall precipitation (wet and dry periods) and fluctuation of water table in Mediterranean countries, has resulted to induce unexpected shrinkage and swelling movements with all the unfavourable consequences. It was observed that light industrial structures and small...
متن کاملThe Effect of Drying Kinetic on Shrinkage of Potato Slices
Objective: Potato is the fourth important food crop after wheat, rice and maize. Shrinkage of food materials has a negative consequence on the quality of the dehydrated product. The main objective pursued in this paper is to investigate the shrinkage amount of potato slices during drying process using vacuum-infrared method. Methods: In this work, the effect of the infrared radiation...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
