Concrete setting time can be reduced or increased depending on climatic conditions by using admixtures. The test for setting time is done using Vicats apparatus. Concrete has Two setting types Practical Knowledge of Civil Engineering M is Mix and 25 means compression strength at the end of 28 days considering concrete cubes of 15 cm cube. Concrete is represented by nomenclature as M-25. Strength of concrete is inversely proportional to water cement ratio. Here water to cement ratio plays important role. Example of Fine aggregate – Sand Example of Coarse aggregate – Gravel Concrete :- Concrete is obtained by mixing cement, aggregate and water as per desired mix. Rapid hardening cement Useful Information for Civil Engineers Īggregates are generally of two Types 1) Fine Aggregate and 2) Coarse Aggregate Fine aggregate is the one that passes through 4.75 mm sieve and retained on 0.075 mm sieve Coarse aggregate is the one that retains on 4.75 mm sieve.Sulphate resisting cement used in corrosive type environment.Low Heat cement used generally in construction of dams.Some of the very important types of cement are Cement is the binder which helps in the bonding of cement, sand along with water. Practical Knowledge of Civil Engineering Practical Knowledge of Civil Engineering, Civil Engineering Basics, Civil Engineering Tips and TricksĬivil Engineering Basics of Construction Material:Ĭement is basically obtained by grinding the stones containing lime and clay. Electrical Conduits shall not run in columns.In Soil Fill as per IS Code, 3 Samples should be taken for core cutting test for every 100 sqm.In steel reinforcement binding wire required is 8 Kg per MT.Compressive Strength of Bricks is 3.5 N/mm.PH Value of Water should not be less than 6.Water absorptions of brick should not be more than 15%.Lap Slices not be used for bar larger than 36 mm.Free fall of concrete is allowed maximum to 1.50 m.Main Bars in the Slab should not be less than 8 mm (HYSD) or 10 mm (Plain Bars) and the distribution not less than 8 mm and not more than 1/8 of Slab thickness.Minim Bars for Square Column 4 Nos and 6 Nos for Circular Column.Longitudinal reinforcement not less than 08% and more than 6% of gross C/S.Chairs minimum of 12 mm diameter bars should be used.For Dowels rod minimum of 12 mm diameter should be used.Chair Spacing maximum spacing is 1 m or 1 No.Lapping is not allowed for the bars having diameter more than 36 mm.These basic civil engineering concepts should be memorized and are useful in day to day work of civil engineer.OTHER POSTS: Civil Engineering Basic Knowledge – Civil Engineering Tips Method Statement for Installation of Anchor Bolts | Setting Out 7 Top Quality Engineer Job Interview Questions That You Should Know Civil Site Engineer Must Know +18 Civil Engineer Tips and Tricks: Practical Knowledge of Civil Engineering Preferably limit the number of steps to 12 per flight.Slope of Stair shall not exceed 40 degrees.Piles Transfer the Loads by friction or by end bearing.Standard size of brick is 19 cm X 9cm X 9cm.
