cement, sand, and water to coat the inside of the drum without reducing the cement content of the mix to be discharged. The materials composing a batch shall be deposited simultaneously

in the mixer. The volume of the mixed materials per batch shall not excess the

concrete and forms shall be thoroughly wet. Reinforcement shall be thoroughly secured in

position and shall be approved by the ENGINEER or his representative.

b. Concrete shall be deposited in its final position without segregation, re-handling or flowing.

Placing shall be done preferably with buggies, buckets, or wheelbarrows. No chutes will be allowed except to transfer concrete from hoppers to buggies, wheelbarrows or buckets.

c. Concrete shall be handled from the mixer to the place of the final deposit as rapidly as practicable by methods of which shall prevent separation or loss of ingredients. It shall be

deposited in the forms of approximately uniform horizontal layers and as nearly as

practicable in its final position to avoid re-handling. The piling up of concrete in the forms in

such a manner as to permit the escape of the mortar from the coarse aggregate shall not be permitted.

d. No concreting will be allowed without vibrators. Segregation due to over-vibration shall be avoided. The vibrator shall be used only to compact the concrete and not to spread the

deposited concrete in the forms. When possible, concreting shall be continuous until section

is completed. Forms shall be clean before concreting is placed. When stoppages of concreting operations occur for any reason, construction joints shall be placed either

horizontally or vertically as indicated by the ENGINEER and provided with shear keys and

dowels to develop bond. Before concreting is renewed, the surface of the poured concrete

against in fresh concrete is to be deposited shall be cleaned of all substance and the aggregate are exposed. Such surface shall further be thoroughly wet grouted before placing new

concrete.

e. Construction joints shall be approved or as directed by the ENGINEER or his authorized

representative.

f. Exposed surfaces of concrete shall be protected from premature drying by covering it with canvass, straw, burlap, sand, earth, and other satisfactory materials and be kept thoroughly

wet for a period of at least (10) days after being deposited. If wood forms were left in place

(during the curing period) they shall be kept sufficiently damp at all times to prevent openings at joints and of the concrete.

8. Forms

care will be exercised by the CONTRACTOR in choice of fitting, and rigidly supporting the

forms.

b. Forms shall be used wherever necessary to confine the concrete and shape it to the required

lines, or to insure the concrete of contamination with materials caving or sloughing from adjacent, excavated surfaces. Forms shall have sufficient strength to withstand the pressure

resulting from placement and vibration of the concrete, and shall be maintain rigidly in

correct position.

c. Forms to be used for exposed concrete surfaces shall be marine plywood and coconut lumber

unless otherwise directed by the ENGINEER.

d. All forms shall be treated with approved oil or saturated with water immediately before

placing the concrete. Any material which will adhere to or discolor the concrete shall not be

used.

e. Unless otherwise ordered by the owner, forms and shoring shall not be disturbed and shall not

be disturbed and shall remain in place for a minimum period of time in accordance with the

ENGINEER or his authorized representatives instruction.

f. Removal of forms. Forms shall be removed in a manner which will prevent damage to the

concrete. Forms shall not be removed without approval. Any repairs of surface imperfections shall be performed at once and curing shall be started as soon as the surface is

sufficiently hard to permit it without further damage.

g. Placing Concrete Through Reinforcement

In placing concrete through reinforcement, care shall be taken that no segregation of the

coarse aggregate occurs. On the bottom of the beams and slabs, where the congestion of the steel near the forms makes placing difficult, a layer or mortar of the same cement-

sand ratios as used in the concrete shall be first deposited to cover the surfaces.

9. Curing

a. All concrete shall be moist cured for a period not less than seven (7) consecutive days by an

approved method or combination applicable to local conditions. The CONTRACTOR shall

have on hand all equipment needed for adequate curing and protection of the concrete and shall be ready to start the curing process immediately following the removal of forms.

b. Moist curing. The surface of the concrete shall be kept continuously wet by covering with water, by continuous spraying, or by covering with burlap, plastic or other approved materials

thoroughly saturated with water and keeping the covering wet by spraying or intermittent

hosing. Water for curing shall be generally clean and free from any elements which might cause objectionable staining or discoloration of the concrete.

10. Splicing

a. Splicing. Where splices in addition to those shown are necessary, they shall be as directed by

the project engineer. Splices shall be by lapping or welding to develop the full strength of the

bars. Unless otherwise indicated the minimum splices length which shall be 24 times the bar diameter or 12 inches whichever is greater.

b. In slabs, beams and girders, splices of reinforcement at points of maximum stress shall be

generally avoided, and may be allowed only upon written approval of splice detailed by the Engineer. Splice shall provide sufficient lap to transfer stress between bars by bonding shear

or by butt welding to develop intension at least 12% of the specified yield strength of the

reinforcing bar. Splices in adjacent bars shall be generally staggered.

11. Repair of Concrete
