##### What is Civil Engineering?

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 […]

##### Variable Head Permeability Test of Soil

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, […]

##### Unconfined Compressive Strength of Cohesive Soil

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 […]

##### Shear Strength of Soil by Direct Shear Test

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 […]

##### Design of Raft Foundation

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 […]

##### Consolidation Test of Soil

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 […]

##### Compaction Test of Soil – Proctor’s Test

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 […]

##### The Liquid Limit of Soil Test

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 […]

##### Determination of Plastic Limit of Soil

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 […]
