Determine Liquid Limit of Soil Specimen by Casagrande Method

The liquid limit test of soil is a laboratory test used to measure the liquid limit of soil and its consistency when it is wet. This test is a part of atterberg limits test with plastic limit test as the other part.Liquid limit is defined as the water content at which a soil changes from a plastic state to a liquid state.The test is performed by a device called a Casagrande apparatus…

Causes of Liquefaction of Soil

You might have been to a beach or near a river bank, have you ever noticed the cohesion-less sands there? I am currently working in a project which is in a mountain range with river crossing through and is actually construction of a dam, during my travelling so many timesI have witnessed people that are, with the help of some bucket mounted on ropes, trying to extract the sand to use it in…

To Determine Plastic Limit Of Soil

When the soil is added with water enough to make it paste like material it is termed as plastic state; in this state the soil can be molded into any shape without breaking and thus called plastic. If more water is added into the soil it will start flowing like a liquid; this…

To Determine Liquid Limit Of Soil Using Casagrande\'s Apparatus

Have you ever visited a beach? Played with sand castles? If yes than you are lucky enough to physically use one of a very vital and important characteristic of soil which is termed as plasticity. Soil when added or applied with water go through many stages and phases. When water or moisture is absent soil is in dry state which is termed as solid state; in this state soil has sufficient shear…

Download Soil Mechanics in Engineering Practice by Karl Terzaghi, Ralph B. Peck, Gholamreza Mesri [PDF]

Soil mechanics originated several decades ago under the pressure of necessity. As the practical problems involving soils broadened in scope, the inadequacy of the scientific tools available for coping with them became increasingly apparent. Efforts to remedy the situation started almost simultaneously in the United States and in Europe, and within short period they produced an impressive array of…

Download Rock Slope Engineering & Civil and Mining by Duncan C Wyllie & Christopher W Mah [PDF]

A variety of engineering activities require excavation of rock cuts. In civil engineering, projects include transportation systems such as highways and railways, dams for power production and water supply, and industrial and urban development. In mining, open pits account for the major portion of the world’s mineral production.  The dimensions of open pits range from areas of a few hectares and…
