3.08 FINISHING UNFORMED SURFACES

A. Thoroughly float surface after concrete has been struck off. Check and level surface plane to a tolerance not exceeding 1/8 in. in 10 ft in any direction.

B. Exterior walks, ramps, pavements, curb and gutter, and driveways shall have a lightly broomed surface with grain perpendicular to direction of travel.

C. Edges shall be neatly trimmed with 1/4 in. radius edging tool.

3.9 CURING

A. Protect freshly placed concrete from premature drying and excessive cold or hot temperatures. Cure formed and unformed concrete for seven days or until 75 percent of the required 28-day compressive strength is obtained, whichever is less.

1. Apply curing and sealing compound to wet cure all surfaces when the surface water has disappeared and the concrete surface will not be marred by walking workmen.

2. KEEP FROM FREEZING. Do not apply curing and sealing compound when air, material and surface temperatures are expected to fall below 40ºF (4ºC) within 4 hours of completed application. Do not mix "water-base" compounds with any compound containing solvent.

3.10 CONCRETE SURFACE REPAIRS

A. Formed Surfaces: Request inspection of concrete surfaces immediately after removal of formwork. After inspection, repair and patch defective areas as soon as practicable.

1. Remove bulges and projections by chipping or tooling. Rub or grind surface after removal.

2. For patching, use dry-pack mortar consisting of one part Portland cement to 2-1/2 parts fine aggregate passing a No. 16 mesh sieve and only enough water as required for handling and placing. Cut out honeycomb, rock pockets, voids over 1/4 in. diameter, and holes left by tie rods and bolts. Remove defects down to solid concrete but, in no case, to a depth of less than 1 in.

Make edges of cuts perpendicular to concrete surface or slightly undercut to provide a key at edge of cut. Thoroughly clean, dampen with water, and brush-coat area to be patched with bonding agent. Place patching mortar before bonding agent has dried. Compact mortar in place and strike off slightly higher than surrounding surface. For exposed-to-view surfaces, patch shall match color of surrounding concrete.

3. For patching less than 1 in. in depth, Contractor may propose a proprietary patching product in lieu of removing concrete to minimum depth of 1

in. Submit proposed product to Contracting Officer for approval.

B. Unformed Surfaces: Repair surfaces that do not meet specified requirements.

1. Floor surfaces not sloped as shown on the Drawings shall be planed to a tolerance not to exceed 1/8-in. in 10 ft in any direction. Any surface defects of sufficient magnitude, as determined by the Contracting Officer, shall be

033000-13 removed by grinding. Spreading dry cement for finishing will not be permitted.

2. Fill cracks with an approved epoxy mortar which will match slab finish in density and performance. Grind filler smooth and even with adjacent surface, free of bumps or depressions at joint.
