Unit 1 Ingredients of Concrete:
Cement: Manufacturing process of cement, chemical composition, grades of cement, hydration, types of cement, Tests for cement: fineness, Standard consistency, setting time, soundness, and compressive strength.Aggregates: classification, requirements, Tests for coarse aggregates: specific gravity, grading of aggregate, Flakiness Index, Elongation Index, Impact value, abrasion value, crushing value. Tests for fine aggregates: specific gravity, sieve analysis, fineness modulus. Alkali aggregate reaction, bulking of sand, Artificial, and Recycled aggregate. Water: general requirements, quality of water.

Unit 2 Fresh Concrete:
Workability: factors affecting, different tests for measurement of workability. Segregation, bleeding. The manufacturing process of concrete: batching, mixing, transportation, compaction, curing of concrete, curing methods.

Unit 3 Hardened concrete:
Strength of concrete: w/c ratio, gel/space ratio, a gain of strength with age, maturity concept of concrete, the effect of the maximum size of aggregate on strength. Test on hardened concrete: compressive strength, comparison of compressive strength between cube test and cylinder test, flexural strength. The relation between compressive and tensile strength. Elastic constants, factors affecting modulus of elasticity, definition, and factors affecting creep and shrinkage. Nondestructive testing: Schmidt’s rebound hammer, ultrasonic pulse velocity method.

Unit 4 Concrete Mix Design:
Objectives of mix design, different methods of mix design, factors affecting mix proportions, quality control of concrete, statistical methods, acceptance criteria, Numerical on mix design by ACI 211.1-1991, IS 10262- 2009andIS 456 -2000. Mix design of fly ash concrete by IS 10262 – 2009.
