Civil Engineering Glossary
Doctors, Engineers, Scientists use words related to their profession when they talk to others! This language is understood by their colleagues and those who are related to them only. Engineers may not fully understand the communication of Doctors and vice versa. Anyhow Civil Engineers talk another language adjunctive to their profession. The word ‘Column’ interpreted by a Journalist is divers from what a Civil Engineer understands. While Civil Engineers talk about ‘Cold Joints’ what a Doctor will understand? So we feature a lot of text which are utilized in Civil Application and there words hold its own message in Civil Engineering.
CivilTalents would like to introduce such works to our upcoming Civil Engineers and others who loves Civil Engineering.
Abrasion | The wearing away of material by friction. Surface particles become detached by a combined action of shearing and tearing. |
Absorption | The surface penetration of fluid in small pores of a material. |
Adhesion | The force acting on the interface of two solid materials |
Admixture | A material other than water ,aggregates and cement used as a component of concrete or mortar and added to the batch during its mixing |
Air Entraining | The capability of material or process to infuse air in the cement paste,mortar or concrete through a system of minute air bubbles. |
Alkalinity | The condition of having or containing alkaline substances with hydroxyl(OH-) ions to cause its pH more than 7. |
Ambient Temperature | The environmental temperature surrounding an object |
Anode | The positive electrode where oxidation occurs due to electrons moving in to the electrode. |
Batching Plant | The plant where concrete is produced using systematic mix design of proportionate usage of cement, water, fine aggregate and course aggregate |
Bye Laws | A set of governing laws set by the Goverment or Local bodies for engineering related design works |
Capillary Action | Rise of fluid in a small diameter ( capillary ) tube due to surface tension of the fluids. |
Carbonation | The process of conversion of calcium hydroxide in hardened cementitious material in to calcium carbonate due to reaction with atmospheric carbon dioxide |
Cathode | At negative potential, electron are drawn away from it and chemical reduction reaction occurs. (Antynom of Anode) |
Cathodic protection | The method of protection of a metal from corrosion by making it a cathode by impressed currant of by introduction of a lesser noble metal. |
Chloride Content | The total amount of chloride ions including the fixed chlorides (non-soluble in pore water) present in concrete or mortar |
Cold Joint | A construction joint formed due to setting of concrete/mortar before placing of next bach of material |
Condition Survey | Condition survey is an examination of structure for the purpose of identifying and defining area of distress. |
Corrosion | The process of deterioration of concrete or reinforcement due to chemical or electrochemical change caused in presence of moisture. |
Cover | The least distance between the surface of the reinforcement and the outer surface of the concrete. |
Codes | IS Codes such as IS 456, IS 800, IS 2233 etc and relevant codes to be implemented |
Creep | The irrecoverable strain caused to a material subjected to constant stress for a long duration. |
Curing | The process of maintaining sufficient moisture and temperature in the concrete after its placing in position, which is absolutely necessary for its complete hydration. |
Delamination | A separation, splitting or cracking roughly parralel and near to surface. |
Depassivation | The loss of alkalinity in the immediate vicinity of steel reinforcement due to carbonation process so as to cause dissolution of its protective passive layer. |
Design Service Life | The life specified for the structure at its design stage for it to adequately perform its functions. |
Disintegration | Breaking into small fragments |
Dry Pack concrete | Stiff mix of concrete / mortar usually compacted by ramming |
