Batching Of Concrete The process of measuring concrete mix ingredients by either mass or volume and introducing them into the mixer. To produce concrete of uniform quality, the ingredients must be measured accurately for each batch. Most concrete today is batched and mixed by ready mixed concrete plants; Fig. 10-2.

Chemical admixtures are added to concrete to modify properties in either the fresh or hardened state. Common admixtures include air-entraining admixtures, which introduce tiny air bubbles that improve freeze-thaw resistance; water-reducing admixtures, which lower the water content needed for a given workability; and superplasticizers, also called high-range water …

Reinforced concrete: • Concrete is strong in compression weak in tension. • Steel in strong in tension • Reinforced concrete uses concrete to resist compression and to hold bars in position and uses steel to resist tension. • Tensile strength of concrete is neglected (i.e. zero ) • R.C beams allows crack under service load.
