Civil Engineering - Shridhar University

PURPOSE
To impart a sound knowledge on the principles of chemistry involving the different application oriented
topics required for all engineering branches.
INSTRUCTIONAL OBJECTIVES
The students should be conversant with:
The role of applied chemistry in the field of engineering
The knowledge of water quality parameters and the treatment of water
The principles involved in corrosion and its inhibitions
Important analytical techniques, instrumentation and the applications
Knowledge with respect to the phase equlibria of different systems.
TECHNOLOGY OF WATER
Water quality parameters: Physical, Chemical & Biological - Hardness of water - estimation of
hardness (EDTA method & O. Hehner's method), Alkalinity - determination - disadvantages of using
hard water in boilers: Scale, sludge formation - disadvantages - prevention - treatment: Internal
conditioning - phosphate, calgon and carbonate conditioning methods - External: Zeolite, ion exchange
methods - desalination - reverse osmosis and electrodialysis - domestic water treatment.
CORROSION AND I TS CONTROL
Corrosion: Basic concepts - principles, mechanism of chemical, electrochemical corrosion - Pilling
Bedworth rule - galvanic corrosion - differential aeration corrosion - pitting corrosion - stress corrosion
- factors influencing corrosion.
Corrosion control: cathodic protection - sacrificial anodic method - corrosion inhibitor. Protective
coatings: surface preparation for metallic coatings - electro plating and electroless plating - chemical
conversion coatings - anodizing, phosphating & chromate coating.
PHASE EQU IL IBR IA
Phase rule: Statement - explanation of the terms involved - one component system (water system only).
Condensed phase rule - thermal analysis - two component systems: simple eutectic, Pb-Ag; Br, Cd -
solid solution Cu-Ni and compound formation Mg-Zn - applications of eutectics.
