Mix	Proportions of cement, sand and aggregate	Normal mixes
		Water- cement ratio		strength N/mm
A B C	1:1:2 1:2:4 !:3:6	0 43 0 62 0 85	34 9 20 3 10 7

Mixes with 30 per cent excess water
Water- cement ratio	strength
0 56 0 86 1 10	23 4 11 6 5 9

From these results we can calculate the per cent reduction in strength for the three mixes due to the excess water.

Now calculate this reduction in strength for mixes B and C, and complete the following table and paragraph:

	per cent reduction in strength
A B C	33

We can conclude that the_____ of concrete is considerably ________as a result of the additional_____. The reason for this is that water combines chemically with cement and an excess of water weakens this reaction on which the strength of the concrete depends.
