G. Test Reports: Test reports shall be prepared in three copies and shall be

distributed by the testing laboratory directly to the Resident project Representative and Contractor in accordance with the quality control section.

1.13 FINISHING UNFORMED SURFACES

A. Buried and permanently submerged concrete blocking and encasement will require no finishing except that necessary to obtain the required surface elevations or contours. The unformed surfaces of all other concrete shall be screeded and given an initial float finish followed by additional floating, and troweling where required.

B. Screeding: Screeding shall provide a concrete surface conforming to the proper

elevation and contour with all aggregates completely embedded in mortar. All screeded surfaces shall be free of surface irregularities with a height or depth in excess of ¼ inch as measured from a 10 foot straightedge.

C. Floating: Screeded surfaces shall be given an initial float finish as soon as the

concrete has stiffened sufficiently for proper working. Any piece of coarse aggregate which is disturbed by the float or which causes a surface irregularity shall be removed and replaced with mortar. Initial floating shall produce a surface of uniform texture and appearance with no unnecessary working of the surface.

Initial floating shall be followed by a second floating at the time of initial set. The

second floating shall produce a finish of uniform texture and color. Unless additional finishing is specifically required, the completed finish for unformed surfaces shall be the float finish produced by the second floating.

Floating shall be performed with hand floats or suitable mechanical compactor�

floats. D. Broom Finish: Surfaces of all exterior concrete stair treads and landings shall be

given a light broom finish providing a non slip surface. Brooming shall be done after the second floating and at right angles to the normal traffic direction.

E. Nonskip Finish: Tread surfaces of all interior concrete and concrete filled pan

type stairs shall be surfaced with aluminum oxide aggregate, “Alumdum” or “Emerundum”. Aggregate shall be uniformly graded from 100 percent retained on a No. 50 sieve to 100 percent passing a No. 8 sieve. Aggregate shall be uniformly distributed during steel troweling at the rate of ¼ pound per square foot, in accordance with the manufacturer’s recommendations, and as acceptable to the Engineer.

F. Troweling: Interior floor surfacing which will be exposed after construction is

completed, surfaces to be covered with resilient floor coverings or seamless floor covering, the exposed portion of the top of equipment bases, the top of interior

033301�11

curbs, and other surfaces designated on the drawings shall be steel trowel finished. Surfaces to be covered with elastomeric deck covering shall be lightly troweled but not burnished. Trowel finishing will not be required for floorswhich are normally submerged. Troweling shall be performed after the second floating when the surface has hardened sufficiently to prevent an excess of fines being drawn to the surface. Troweling shall produce a dense, smooth, uniform surface free from blemishes and trowel marks.

G. Finishing Surfaces for Bonding: All surfaces to be covered with concrete or

topping shall be float finished. All laitance, surface mortar, and unsound material shall be removed by brushing or air blasting at the time of initial set. Surfaces shall be rough, clean and sound. Floors and other flatwork surfaces to receive topping shall be given a broom finish.

H. Edging: Unless specified to be beveled, exposed edges of floated or troweled

surfaces shall be edged with a tool having ¼ inch corner radius. New retaining wall shall have exposed edges with 1” beveled edges.

1.14 CURING

A. Concrete shall be protected from loss of moisture for at least 7 days after placement; however, when concrete is being protected from low temperatures, the time period for curing by saturation shall be one day less than the duration of the low temperature protection.

Curing of concrete shall be by methods which will keep the concrete surfaces

adequately wet during the specified curing period. All concrete in the rapid mix/splitter structure, basin, filters, and clearwell shall be water cured; membrane or film curing will not be acceptable.

B. Water Curing: Water saturation of concrete surfaces shall begin as quickly as

possible after initial set of the concrete. The rate of water application shall be regulated to provide complete surface coverage with a minimum of runoff. The application of water to walls may be interrupted for group cleaning only over the areas being cleaned at the time, and the concrete surface shall not be permitted to become dry during such interruption.

C. Membrane Curing: Membrane curing compound may be used in lieu of water

curing on concrete which will not be covered later with topping, mortar, or additional concrete.

Membrane curing compound shall be spray applied at a coverage of not more

than 300 square feet per gallon. Unformed surfaces shall be covered with curing compound within 30 minutes after final finishing. If forms are removed before the end of the specified curing period, curing compound shall be immediately applied to the formed surfaces before they dry out.

Curing compound shall be suitably protected against abrasion during the curing

period. D. Film Curing: Film curing with polyethylene sheeting may be used in lieu of water

curing on concrete which will be covered later with mortar or additional concrete, or will otherwise be covered or hidden from view.

033301�12

Film curing shall begin as quickly as possible after initial set of the concrete. Polyethylene sheeting shall completely cover the surfaces. Sheeting shall overlap the edges for proper sealing and anchorage. Joints between sheets shall be sealed. All tears, holes, and other damage shall be promptly repaired. Covering shall be anchored continuously at edges and shall be anchored on the surface as necessary to prevent billowing.

1.15 REPAIRING DEFECTIVE CONCRETE

A. Defects in formed concrete surfaces shall be repaired within 24 hours, to the satisfaction of the Engineer, and defective concrete shall be replaced within 48 hours after the adjacent forms have been removed. All the concrete which is honeycombed or otherwise defective shall be cut out and removed to sound concrete, with edges square cut to avoid feathering.

Concrete repair work shall conform to Chapter 9 of ACI 301 and shall be

performed in a manner that will not interfere with thorough curing of surrounding concrete. Repair work shall be adequately cured.

1.16 FINISHING FORMED SURFACES

A. Fins and other surface projections shall be removed from all formed surfaces except exterior surfaces that will be in contact with earth backfill and are not specified to be dampproofed. A power grinder shall be used, if necessary, to remove projections and provide a flush surface. Surfaces to be dampproofed shall have fins removed and tie holes filled, but no additional finishing will be required.

B. Tie Holes: Tie holes in all formed surfaces shall be cleaned, wetted, and filled

with patching mortar. Tie hole patches shall be finished flush and shall match the texture of the adjacent concrete.

1.17 TOLERANCES

A. Unless otherwise specified, tolerances for cast�in�place concrete work shall be as stipulated in ACI 347. Formed surfaces stipulated in Article 3.3.8 of ACI 347 shall be considered as Class A for architectural concrete as specified herein, and Class C for all other concrete work.

The settling basin floor shall be accurately finished to a uniform slope, and shall

be within one inch of the shape indicated on the drawings.

1.18 CONCRETE FOR PIPE BLOCKING AND ENCASEMENT

A. Concrete for buried blocking and encasement of pipe shall conform to the limiting requirements specified herein, except that air�entraining and water�reducing admixtures may be omitted and the cement factor and total water content may be adjusted to provide a minimum compressive strength of 3,000 psi at 28 days. Concrete shall have a slump of not less than 2 inches `or more than 5 inches when placed.
