 Abstract

This experimental study on workability of concrete on different water-cement ratio concrete mixture. it is usually expressed in litre of water required per bag (50 kg) of cement. A rich mix of concrete gives a higher strength than a lean mix of desired workability with less quantity of water. Thus lower the water-cement ratio, greater is the strength of concrete, strength of concrete decrease as the the water-cement ratio increases. This fact is illustrated by plotting a graph with water-cement ratio as abscissa and compressive strength, in case the water-cement ratio is less than 0.45 the curve is seen bending downwards. This indicates that the concrete mix having water-cement ratio less than 0.45 by weight is not workable and causes honey-comb structure .but amount of water to be added also plays an important role in this
