Civil engineering is a discipline of professional engineering which mainly relates and deals with the configuration and design, building of those structures, and upkeep the sustainability of the physical as well as the naturally formed structures comprising the likes of roads, bridges, buildings, canals and dams. Civil engineering is conventionally categorized into a variety of sub-disciplines. It […]
Read More →For determination of the permeability of a soil specimen by the variable head permeameter Theory The variable head permeameter is utilized to compute the permeability of comparatively less porous soils. The coefficient of permeability is expressed by: Where, = initial head, = final head, t= time interval, a= cross-sectional area of the liquid stand pipe, […]
Read More →Theory: The unconfined compressive strength ( ) basically refers to the load per unit area at which the cylindrical sample of a cohesive soil falls in compaction. Where P= axial load at failure, A= corrected area = , where is the initial area of the specimen, = axial strain = change in length/initial length. The […]
Read More →To assess the shear strength of a sandy soil sample by direct shear test: Theory Shear strength of a soil is its maximum resistance to shearing stresses. The shear strength is given as: Where, c’ = effective cohesion, = effective stress, = effective angle of shearing resistance. The shear tests could be undertaken under three […]
Read More →Design Considerations of Raft or Mat Foundation: In those cases, where the load transmitted by the columns in a structure are so substantial or the reasonable soil pressure so little that individual footings would cover more than around one-portion of the region, it might be ideal to give a persistent footing under all columns, wall […]
Read More →To determine the consolidation properties of a soil specimen Theory Consolidation of a saturated soil happens because of the exclusion of water under static, sustained load. The consolidation properties of soils are necessary to forecast the magnitude and the rate of settlement. The following properties are acquired from the consolidation test. Coefficient of compressibility, Coefficient […]
Read More →Compaction test of soil is also additionally called as Proctor’s test. It is normally undertaken to understand compaction properties of varied soils with alteration in moisture proportion. For assessment of the compaction properties of a soil sample by proctor’s test Theory Compaction refers to the procedure of densification of soil by plummeting air voids. The […]
Read More →For assessment of the liquid limit of soil sample Theory The liquid limit of a soil refers to the water proportion at which the soil performs virtually like a liquid, however has minor shear strength. It flows to adjacent the groove in mere 25 blows in Casagrande’s liquid limit equipment. Since, it is hard to […]
Read More →For assessment of the plastic limit of soil sample Theory The plastic limit of a soil refers to the water proportion of the soil beneath which it ends to be plastic. It then starts to crush when rolled into filaments of 3mm diameter. Tool and Equipment Porcelain evaporating dish about 120mm diameter Glass plate with […]
Read More →Reciprocating pump refers to the positive displacement pump. The provided pump is solitary acting single cylinder pump comprising of an air vessel. It could be utilized for minimum discharge at greater heads. Preparing is not compulsory since it is a positive displacement pump. Reciprocating pumps are utilized in pumping water in hilly regions. Reciprocating pumps […]
Read More →Self-priming pumps are characteristically designed and manufactured in such configuration that it permits the pump to re-prime itself normally under lift situations. These pumps are quite operative to the end user in that they will eradicate the necessity for foot valves, vacuum and additionally ejector pumps which could easily become clogged or be unworkable to […]
