Laboratory tests on specific gravity, unit
weight, moisture content, absorption of coarse and fine aggregates, initial and
final setting time of cement, Tensile and compressive strength test on cement
mortar; gradation of coarse and fine aggregates Normal consistency; resistance
to abrasion of coarse aggregates: effect of water/cement ratio on compressive
strength and consistency of concrete, design and preparation of concrete
mixture and determination of cylinder strength both for tension and
compression.
