PROJECT SPECIFICATION

1. Applicable standardized and particular

specifications

For the purposes of this contract the following

standardized and particular specification shall

apply

SANS 1200 G: CONCRETE (STRUCTURAL)

FINISHING WITH MECHANICAL TROWEL

Power floating should not commence until

such time as the concrete surface has lost its

sheen and barely shows footprints.

All laitance on the surface of the fresh

concrete screed resulting from the compaction

of concrete must be struck off prior to

mechanical trowelling.

Over trowelling, causing an excessive cement-

water paste to come to the surface, must be

strictly avoided.

CURING

Curing should commence as soon as finishing

operations have been completed and should

be continued for at least 7 days. The method

of curing must be approved by the engineer.

JOINTS

The joints should be formed by cutting grooves

3 mm wide by 25 mm deep into the screed.

These joints must be aligned to the joints in

the structural slabs or the slabs on fill, and

must be cut within 8 hours of placing the

screed.

The coating system shall be from one manufacturer only. The paint manufacturer’s instructions shall be strictly adhered to.

3.1.1.2 Surfaces in contact with each other after assembly or erection shall receive the primer beforehand, except for faying surfaces for friction-grip fasteners.

3.1.1.3 The application of the final coats of paint before erection will be permitted by the engineer only in special circumstances or where specified elsewhere.

3.1.1.4 After erection of the steelwork, the specified paint system shall be reinstated in all areas where it has been damaged. All fasteners shall also be treated in accordance with the specified paint system.

3.1.1.5 No painting on the site shall be done in inclement weather or when humidity or frost is

- Prior to treatment, the steel surface shall be cleaned of dirt and grease

- Heavier layers of rust shall be removed by chipping

- All loose mill scale, rust and foreign matter shall be removed by very thorough scraping, wire-brushing, machine-brushing, grinding, etc

- Finally the surface

shall be cleaned by vacuum cleaner, with clean dry compressed air, or with a clean brush

- The surface shall have a pronounced metallic sheen with an appearance equal to or better than that shown on the prints designated ST 3 in SIS 05 59 00 or ISO 8501

3.1.2.2 Blast-cleaning

This treatment may be used but is not obligatory unless so specified hereinafter. If blast cleaning is preferred to normal scraping and wire brushing, the final surface shall be equal to or better than that specified in subsubclause 3.1.2.1.

Paint system for newly galvanized surfaces

3.2.1 Recommended surface preparation:

- Degrease with Plascon Aquasole Degreaser GR 1 or similar approved. Any cement or foreign material must also be removed from the metal surface.

- Rinse with clean running water while protecting the floors and walls.

- Wash with Galvanised Iron Cleaner GIC 1 by Plascon, or similar approved.

- Rinse with clean running water and allow to dry. Protect the floors and walls.

3.2.2 Apply one coat of Plascon Aquafast Etch Primer no EMS 18 or similar approved to a total dry thickness of 35 micron. Must be overcoated within 72 hours to avoid excessive hardening.

3.2.3 One final coat as specified in table 3.1.

HOT DIPPED GALVANIZING (See also subclause 5.9in SANS 1200H)

Steelwork described as "galvanised" shall begalvanised after manufacturing and beforedelivering to site by means of the hot dippedprocess complying with the minimumrequirements of SANS 121 (SABS ISO 1461),1999 latest amendment. Structural steelmembers shall be given an 85 micron thickgalvanised coating or such other thickness asmay be specified in accordance with SANS 121(SABS ISO 1461) (Table 1.)Damaged surfaces must be thoroughly cleanedand if welding has been carried out all slag mustbe removed preferably by the use of a chiselhammer.

Before galvanising all surfaces of the metalworkshall be thoroughly cleaned of all scale and rust

UNISA

B2051 REV 1

by shot-blasting in accordance with SANS 10064or by pickling and then fluxed ready forgalvanising.

The zinc coating shall be even and continuousover all surfaces, free of bare spots, dull or roughpatches, blisters or other imperfections. The zinccoating shall show no signs of peeling and shallbe uniform in thickness.

All M8 and greater bolts, nuts, screws and otherthreaded components, shall be hot-dip galvanisedto SANS 121 (SABS ISO 1461) (previouslyarticles type C.)

Repairing of damaged coatings

Plant repairs

Should any black spots or uncoated areas greaterthan 5 mm2 (individual) or 25 mm2 (collective) perm2 or per m run be present after galvanizing, thecoating shall be repaired. This is to be carried outusing abrasive blasting following by zinc metalspray. The zinc metal spray shall be applied atleast 25 % thicker than that specified and shalloverlap the damaged area by 20-25 mm. Thefinished coating shall be wire brushed to removeany excess metal spray.

Hot patch soldering is an alternative at the plantbut is seldomly used, as the method needs to beconducted while the product is still hot beforequenching.

Site Repairs

Zinc metal spray as set out above.

The recommended alternative is to use a zinc richpaint provided it has at leas 90 % zinc in the dryfilm, by mass. The paint should be a zinc richepoxy in conformance with SANS 926. A singlepack zinc rich paint such as Plascon’s “PlascozincPolygalv Primer” or equal can be applied.
