CE 121 No. of hrs/week : 01+02
No. of credits : 02
Tests are conducted to develop an understanding of the physical and mechanical properties of materials used in construction.
(1) Tests on cement: Specific gravity, fineness, soundness, normal consistency and setting times, compressive strength of cement mortar cubes.
(2) Tests on fine aggregate: Specific gravity, bulking, sieve analysis - fineness modulus, moisture content, bulk density.
(3) Tests on coarse aggregate: Specific gravity, sieve analysis - fineness modulus, bulk density.
(4) Tests on bricks and tiles (roofing and flooring): Water absorption, breaking loads.
(5) Tests on cement concrete:
a) Tests on fresh concrete: workability, slump, vee-bee compaction factor tests.
b) Tests on hardened concrete: compressive strength of cubes and cylinders, split tensile strength test, flexure test, non-destructive testing.
c) Tests on bituminous materials: Specific gravity, flash & fire points, penetration, softening point, viscosity and ductility tests.
