CIVIL ENGINEERING MATERIALS & CONSTRUCTION PRACTICES

CIVIL ENGINEERING MATERIALS & CONSTRUCTION PRACTICES

Group A
INTRODUCTION TO CIVIL ENGINEERING MATERIALS
stone, timber, cement, steel, plastics, concrete. Engineering properties of materials-density, strength (compressive, tensile, flexural, shear, etc.), modulus of elasticity, fatigue, limit, creep, shrinkage, relaxation, permeability, fire resistance. Materials and environment-effect of environment on materials. Classification of environment-temperature, humidity, rain, fire. Steel: Manufacture, rolled sections, properties, classifications.
CEMENT
Manufacture-wet and dry processes, constituents and constitution, propertiessetting, strength, durability, classification-high early strength, low alkali, rapid hardening.
CONCRETE
Constituents-coarse and fine aggregates, cement, water. Mineral admixtures-fly ash, blast furnace, slag, silica fume. Chemical admixtures-air entraining, set retarding and accelerating, super plasticising. Fresh concrete-workability, air content, segregation. Hardened concrete-strength, hardness, modulus of elasticity, modulus of rupture. Special concretes-fibre, reinforced, shortcrete, underwater, high strength. Deterioration and durability-reinforcement, corrosion, carbonation, alkali aggregate reaction.

Group B
BRICKS
Manufacture, classification. Other materials. Standardization and standards-need to have standards and some common international standards. Relevant Indian standards (commonly used standards to be listed with brief description). Quality control. Nondestructive testing and evaluation.
CONSTRUCTION PRACTICES
Standards relevant to quality control at site. Safety issues. Quantities and estimation. Tender document. Contracts-unit rate, lumpsum, turnkey. Project management-CPM, PERT, bar charts, pie diagrams, escalation, depreciation.
