The term characteristic strength means the value of the strength of concrete below which not more than 5 per cent of the test results fall.

t
able cube strength 3hall be increased by an amount to be determined by the Engineer.

The actual coment contends and aggregate/cement ratios will depend ou the closeness of control which the Contractor is prepared, to exercise in production and 
upcn the quality of materials used. Where necessary the Engineer may impose an upper or lower aggregate/cement ratio which shall not be exceeded for any class of con crete.
(3) Before any concrete is placed in the Works the Contractor shall submit to the Engineer for his approval full details of the mixes he proposes to use for each class of concrete together ’with their anticipated aver age strengths. These mixes shall be based on the re sults of trial nixes as specified hereafter.
Concrete Mix Designs
114.

Trial Mixes
by the Contractor and the Engineer to 'determine the
mixes which will satisfy the Specification ’with the
available materials. These mixes shall be designed with 
due regard for the workability necessary to allow the Contractor to place and compact the concrete with the equipment he proposes to use in any particular situation.
The mixes shall be designed to have mean strengths that are greater than the specified character
istic cube strengths by a margin that is governed by the standard deviation expected from the concreting plant. 
The standard deviation shall be calculated from at least
40 individual cube results each representing separate batches of similar concrete produced by the same plant
and under the same supervision, except that no standard deviation less than 5.5 K/mm^ sha.ll be used as a basis
for designing a mix. In the abaeice of such previous information a standard 7 H/mm^ shall be used for initial mix design purposes. It is assumed that the same stand
ard deviation applies to both the 7 day and 26 day strengths.
415- Unless there are existing data showing that
the proposed mix proportions will produce the grade of concrete required with adequate workability for full compaction by the method to be used in production, trial mixes shall be prepared under full scale conditions and tested in accordance with B.S.1881 "Methods of testing concrete*. Trial mixes shall also be made subsequently whenever a change is intended in materials or in’the proportions of the materials to be used. Representative samples of the materials to be used shall be taken and three trial mixes using the proposed proportions shall
be made on different days. The workability of each of these three trial mixes shall be determined and a batch of six cubes from each mix shall be made, three for
tests at 7 days and three for tests at 28 days. The Engineer will normally approve the proposed mix propor tions provided the average strength of the three trial mixes is no less than the designed mean strength minusConcrete 115

Further trial mires shall he made if the range
of strength, that i3 the maximum minus the minimum, of
the thr^p cube results in any batch exceeds 155» of the
average of that batch, or if the range of the three
batch averages exceeds 20^ of the overall average of
the batches.
416.                 Test    cubes    shall    be    made,    cured,    stored,    trans- oorted entd tested in compression in accordance -with
B.S.1881 "Methods cf testing concrete". The method of compacting cubes by vibration 3hall be subject to the approval of the Engineer.
A sample of concrete shall be taken at random on eight separate occasions during each of the first
five days of using a mix. Thereafter a sample shall be taken from at least <#£ of the batches made, and at
least one sample shall be taken each day any concrete
of a particular grade is made. The number of samples
per day and the times which they shall be taken shall
be varied at random or as directed by the Engineer.
Prom each sample two cubes shall be made for testing at 29 days and one for testing at 7 days for
control purposes.
To ensure that the mix proportions are suit able for a particular grade of concrete 29 day test
cube results shall satisfy the four conditions given 
below.
The works test 29 day cube results shall be examined both individua 1 Ly and in consecutive (hut not overlapping) sets of four, for which the average and 
the range of each set shall be calculated. The mix proportions shall be modified to increase the strength if, in the first ten consecutive (but not overlapping)
sets, any of the following conditions are not satis
fied;
1.     not more than two individual results of the
40 cube tests shall fall below the specified characteristic cube strength,
2.     no value of the range in any set shall exceed 5.2 times the designed standard deviation,
3.     no value of the average of any set shall be
les3 than the specified characteristic
strength plus the designed standard deviation, and

4.           nor no re than one set shall have an average
which is le33 than the specified character

After ten ccnsecurivo seta of results have
been obtained, the overall average and the standard 
deviation of the 40 results shall be calculated and any 
appropriate modifications made to the mix proportions. 
Subsequently, if ary of the foregoing conditions do not
apply to the individual results or the sets of four, 
the overall average and. the standard deviation of he
previous consecutive 40 results, including the non
complying set shall be calculated. If the overall
average strength minus 1.6 times the standard deviation 
is less than the specified characteristic works cube
strength, then the mix proportions shall be modified.
If any 28 day works test cube result is less
than ao£ of the specified characteristic cube strength, 
the Engineer will consider whether the concrete Ln the
Works represented by the cubes falling to meet the
specified strength requirements can be accepted and he
may order that any or all of the follow* ng actions
shall be taken.
A. The adjustment of the mix and/or improvement
to the standard of quality control.
3.    The    cutting    of    test    cylinders    from    the    con crete   for   ATam-t   natjon   and   tpgt-i   ng   of   speci mens prepared therefrom.
C.    The carrying out of load testa or other non destructive teats on concrete structures.
D.    The cutting out and replacement of such vol umes of concrete as at his direction he con siders to be defective.
Where the Engineer orders action to be taken under Sub-Clause 3 above, the Contractor shall out
cores from locations selected by the Engineer. These shall be tested in accordance with B.S.1881 "Methods
of testing concrete". If the strength of these cores, when corrected by the reduction of 0.7 H per sq.mm, for each week of age In excess of 28 days is not less than 75$ of the specified characteristic cube strength, then the concrete will not be required to be cut out.
Concrete having a 28 day characteristic strength in excess of 20 H per sq.mm, shall be tested 
as the Engineer may direct for Water Absorption, Drying Shrinkage, and Moisture Movement, for which purnose 100nn cubes and 75 x 75 prisms shall be prepared and tested in accordance -with B.S.J40 "Precast concrete

to determine the duration of curing or to check testing errors.
418.    (l) The concrete shall be of such consistency that
it can be readily transported, placed and compacted in 
the Works without segregation of the materials. The resulting concrete shall be uniform and free from honeycombing.
(2) Where necessary and before the nixes are approved the Contractor shall supply a section of form work complete with reinforcement fixed Ln position and generally representative of the sections comprising the Works. This formwork shall be'*fflled with concrete ‘ produced for the trial mixes and compacted in the same manner and. with the same equipment to be used on the Works. The appearance of the concrete after striking 
the formwork shall be to the satisfaction of the Engin

be inqfca.11 with gauges marked so that the amount fed into the mi tax may be easily ascertained.
The water-cement ratio fcr the various classes of concrete shall be determined by the trial mixes and 
in no case shall the water-cement ratios 'used be
al l nwpa to exceed by more than 10 per cent. those determined by the trial mixes.
Efficient means shall be provided for deter mining the moisture content of the sand and coarse aggregate at all times.
The Contractor shall be required to have an accurate knowledge of the moisture content of all sand and coarse aggregate as they reach the mixer and he shall make such adjustments to the mix as are necessi tated by change in the moisture content of all aggre gates.

their slopes shall not be such as to cause segregation 
and suitable spouts or baffles shall be provided where necessary. Concrete shall not be dropped through a
