About Civil Engineering, Did you know these about? 12 basic things you should know about the civil engineering. 1. The weight of the Reinforcement Steel is calculated with the help of the formula, D2/162. Where D is the diameter of the reinforcement. 2. For the cube test two types of specimens either cubes of 15cm X 15cm X 15cm or 10cm X 10cm x 10cm depending upon the size of aggregate are used. For most of the works cubical molds of size, 15cm x 15cm x 15cm are commonly used. 3. The concrete cubes are filled into the 3 layers 4. The slump cone is filled into the 4 layers 5. The minimum % of the steel used in the column is 0.08% of the gross area 6. The maximum % of the steel used in the column is 6.00% of the gross area 7. The minimum % of the steel used in the beam is 1.00% of the gross area 8. The maximum % of the steel used in the beam is 2.00% of the gross area 9. The minimum % of the steel used in the slab is 0.70% of the gross area 10. The maximum % of the steel used in the slab...

6 most important 1 liners from the subject Steel taken from the field Civil Engineering 1 Liners from the subject Steel Poisson's ratio "Poisson's ratio v" is a measure of the Poisson effect, which is the deformation (expansion or contraction) of material in directions perpendicular to the specific direction of loading in materials science and solid mechanics. The negative of the ratio of transverse strain to axial strain is Poisson's ratio. "v" is the amount of transversal elongation divided by the amount of axial compression for modest values of these changes. The Poisson's ratio of most materials is between 0.0 and 0.5. Poisson's ratio is around 0.5 in soft materials like rubber, where the bulk modulus is larger than the shear modulus. Poisson's ratio is approaching zero in open-cell polymer foams because the cells collapse with compression. The Poisson's ratios of several common solids are in the range of 0.2-0.3. Simeon Poisson, ...

Notes on Building Material and Construction (in short form, BMC) Common Building Materials from Building Material and Construction are Cement Lime Aggregates Mortar Admixture Concrete Bricks Stones Steel Timber Miscellaneous Cement Cement is an organic building material with a binding property of construction that was invented by Mr. Joseph Aspedin in the years 1824-1825. Calcareous Compounds (Compounds containing Ca, Hg) and Argillaceous Compounds make up the majority of cement (Compounds having Silica, Aluminium Oxides) Examples of Calcareous Compounds are Limestones, Cement Rocks, Chalk, Marine Shell, Alkali Waste Examples of Argillaceous Compounds are the Clay, Slate, Ash OPC's Different Constituents (i.e Ordinary Portland Cement) Lime (CaO - 62% to 67%) It gives cement its strength and stability. If there is so much lime in the mortar, it becomes unsound, allowing it to spread and then disintegrate. A lack of lime decreases the strength of ...
