DESIGN OF CONCRETE STRUCTURES-I (BTCE-403)

Part A: CONCRETE TECHNOLOGY

1. CEMENTS & ADMIXTURES: Portland cement – chemical composition – Hydration, Setting
of cement – Structure of hydrate cement – Test on physical properties – Different grades of
cement – Admixtures – Mineral and chemical admixtures.

2. AGGREGATES: Classification of aggregate – Particle shape & texture – Bond, strength &
other mechanical properties of aggregate – Specific gravity, Bulk density, porosity,
adsorption & moisture content of aggregate – Bulking of sand – Deleterious substance in
aggregate – Soundness of aggregate – Alkali aggregate reaction – Thermal properties – Sieve
analysis – Fineness modulus – Grading curves – Grading of fine & coarse Aggregates – Gap
graded aggregate – Maximum aggregate size.

3. Properties of Concrete: Workability – Factors affecting workability – Measurement
of workability by different tests – Setting times of concrete – Effect of time and
temperature on workability – Segregation & bleeding – Mixing and vibration of
concrete – Steps in manufacture of concrete – Quality of mixing water, Abram’s Law
, Factors affecting strength; Characteristics strength of concrete, Target strength,
Modulus of elasticity, Modulus of rupture

4. MIX DESIGN : Factors in the choice of mix proportions – Durability of concrete –
Quality Control of concrete – Statistical methods – Acceptance criteria –
Proportioning of concrete mixes by various methods – BIS method of mix design.
