pletely covered with mortar and the batch is of uniform color end consistency.
The actual time of continuous miAng of each batch in the machine, after all
ingredients are deposited therein, shall in no case be less than 12 minutes.
The mixer shall be equipped with an attachment for satisfactorily locking the
discharging device, so as to prevent the emptying of the mi:-Ier until all the
materials have been mixed tog-ether for the ninimum time required. The entire
contents of the drum shall be discharged before any materials are placed there-
in for the succedcling batch.
Concrete mixed in Central Mixing Plants na-,tr be used providing the additional
specifications hereinafter provided for Central Mixing Plants are complied
with.
G. CTITSIST31MY: Only sufficient water shall be added to allow free flow of
concrete from the mixer and easy working in the forms; it shall aot be added
in such quantity as to cause separation of the ingredients by gravity or in
handlin(:; or to cause the concrete, when deposited in the forms, to quickly
assume a level surface without handling.
In general, the amount of water used in each batch shall be determined by
the Magineer so as to insure strength of the concrete when poured -up to re-
quirements shown on plans. In no case, unless specifically permitted by the
nagineer, shall water sufficient to result in slumps of more than 5 inches
be permitted. After the slump and proportions are established, then the water
shall be so measured as to insure the same quantity in successive batches of
concrete made of the same quality and quantity of aggregate and cement.

ed revolving drum or revolving blade type so constructed as to produce a thor-
oughly mixed concrete with a uniform distribution of the materials throughout
the mass and shall be equipped with a discharge mechanism which will insure
the discharging of the mixed concrete without segregation.
(2) The mixer drum shall be water tight when closed and shall be equipped
with a locking device which will automatically prevent the discharging of the
mixer prior to receiving the required number of revolutions.
(3) The entire quantity of mixing water shall be accurately measured
and controlled. Each batch shall be mixed not less than fifty (50) nor more
than one hundred fifty (150) revolutions at the rate of rotation specified
by the manufacturer as mixing speed. Any additional mixing shall be done
at a slower speed specified by the manufacturer for agitation, and shall be
continuous until the batch is discharged.
(4) The rate of delivery of the mixed concrete shall be such that the
interval between loads shall not exceed ten (10) minutes. The concrete shall
be delivered to the site of the work and discharged from the mixer within a
period of ninety (90) minutes after the introduction of the mixing water with
the dry materials.
J. CONVEYING: The method of conveying concrete from the mixer to place shall
be such as to prevent loss of mortar, separation of ingredients or change in
i

consistency. Concrete shall not be dropped through a vertical height exceeding
ten (10) feet, except through a pipe or closed chute which is kept filled by
a continuous sliding of concrete,
K. PLACING: Concrete shall be deposited in the footing, excavations or forms
so as to maintain a horizontal surface and shall be thoroughly and continuously
worked into all spaces and around all reinforcement so as to from a dense,
voidless mass.
The coarse aggregate shall be worked away from contact with the forms so as to
form a smooth, hard exposed concrete suface.
Surfaces to be covered by concrete in forms shall be left as rough as practi-
cable. Such surfaces when required shall be provided with a recess formed by
placing timbers or forms in the green concrete so as to key the footing to the
concrete above in a way satisfactory to the Engineer. The footing shall be pro-
tected against the lodgement of foreign material and be thoroughly cleaned and
wet immediately before placing additional concrete.
L. FINISHING: All concrete surfaces shall be true and even, free from honey-
combing, stone pockets, depressions, projections, or air pockets.
Unless otherwise specified the forms for all work requiring a rubbed finish
hereinafter specified, shall be removed as soon as safety to the work Grill per-
mit (usually not less than twenty-four (24) hours) , all projecting bolts or
wires which pass through the body of the concrete shall be cut off one-half
(211) inch below the surface of the concrete, and the holes thus formed filled
with a 1:2 cement mortar. Then the surface shall be given a "rubbed" finish
made by rubbing with a carborundum block until a smooth and uniform surface
free from board marks is secured. Care shall be observed to use plenty of
water by throwing it on the concrete with a brush or broom and not by dipping
the block in water. A mortar finish will not be permitted. When the structure
is completed, all surfaces requiring the rubbed finish shall be rubbed the
second time, using plenty of water and brushing the surface horizontally to
give a smooth, light colored finish.
The surfaces of the structure requiring the "rubbedu finish shall be as follows:
All exposed surfaces of coping and any other exposed surface of the foundation.
On all surfaces not requiring a "rubbed" finish, the bolts or wires which pass
through the body of the concrete shall be out off flush with the surface of the
concrete.
The floor Slabs shall be poured and struck off over screens placed on not
over eight (8) foot .centers. The concrete shall be hand finished to a smooth
and eves surface by means of steel trowels. Before the concrete has its ini-
