1、SSPC-TU 10December 1, 2002Editorial Revisions November 1, 2004(PCSI) who joined the SSPC committee and participated in the consensus review process. This joint technology update was devel-oped by the SSPC Unit Committee C.7.1 on Concrete Coatings and Surfacings with the assistance of members of the
2、Polymer Coatings and Surfacing Institute 10-1311. Scope and DescriptionThis Technology Update discusses techniques and pro-cedures to enhance performance of concrete fl oors by use of resinous systems greater than 20 mils. Flooring systems covered by this TU include: Thick fi lm systems (500m), self
3、-leveling systems, slurry systems, broadcast systems, mortar systems, fabric-reinforced systems, spray applied systems, and non-waterproofi ng and underlayment membranes. Thin-fi lm coatings (500 m) and sealers, terrazzo fl ooring, mem-brane systems designed for waterproofi ng, and primary and secon
4、dary containment systems are beyond the scope of this technology update. The technology update outlines techniques and procedures, with additional specifi c details provided in the appendices. Appendix A provides background information and requirements for the concrete substrate to which the surfaci
5、ng is applied. Appendix B provides detailed information on the techniques and procedures described below. The Technology Update is intended for use by owners, applicators, and others in the coatings and surfacings industry. It addresses the unique application properties of coating and surfacing conc
6、rete fl oors, and should not be used for other purposes. 2.

14、f Concrete Sub-fl oor Using Anhydrous Calcium Chloride3. Defi nitions5Bleeding: The autogenous fl ow of mixing water within, or its emergence from, newly placed concrete or mortar as caused by the settlement of the solid materials within the mass. Also called water gain. (FCC)Broadcast Flooring: Usu
15、ally neat (unfi lled) resins or slurries (aggregate fi lled) applied over a fl oor into which aggregate is blown by specialized equipment or thrown by hand, in a raining fashion, into the wet, uncured matrix and allowed to cure.Broadcast to Saturation: Aggregate broadcast into a wet matrix until the
16、 surface does not show wetness of the resinous layers below.Carbonation: Reaction between carbon dioxide and a hydrox-ide or oxide to form a carbonate, especially in cement paste, mortar, or concrete. The reaction with calcium compounds to produce calcium carbonate. (FCC)Capillary space: Microscopic
17、 channels on concrete small enough to draw liquid water through to be adsorbed on the inner surface. (FCC)Hydration (of Cement): The reaction of water with the calcium silicate, aluminate, or aluminum/ferrite components of fi ne Portland cement grains necessary for the setting and curing of concrete
18、. Hydration results in the formation of calcium hydroxide and colloidal gels that occupy a larger volume than the original cement.Keyed (Key in): The process of removing the concrete sub-strate in order to create a durable termination border for a fl uid-applied fl ooring system. Lap Length: The len
19、gth of overlapping of steel rein-forcing bars.Planarity: The general evenness of a substrate in an intended dimension. Planarity should not be confused with levelness. A sloped area, for example, should be “in plane,” without low or high spots, but is not level.Pozzolan: A siliceous or siliceous and
20、 aluminous material, which in itself possesses little or no cementitious value but will, in a fi nely divided form, and in the presence of moisture, chemically react with calcium hydroxide at ordinary temperatures to form compounds possessing cementitious properties. (FCC)Recoat Time: The amount of
21、time required for a coating, slurry or mortar to dry or cure before a subsequent coat can be ap-plied successfully.Slump: A measure of the consistency of freshly mixed concrete, mortar, or stucco equal to the subsidence measured for the nearest 1/4 inch (6 mm) of the molded specimen immediately afte
22、r removing the slump cone. (FCC)Slurry Floor: Generally 100% solids or zero VOC chemi-cally cured resins, incorporating use of inert fi llers or powders, producing a fl owable, but not necessarily self-leveling mixture. Slurry fl oor materials are usually troweled to the thickness of the largest agg
23、regate in the material.Resin: General term applied to a wide variety of polymeric products, which may be natural or synthetic. They may vary widely in color. In a broad sense, this term is used to designate any polymer that is a basic binder material for coat-ings and plastics.Self-Leveling Flooring
24、: Resinous or polymer-cementitious based materials that tend to fl ow out when applied over a fl oor, seeking its own level. Self-leveling systems generally require built-up termination strips as opposed to key-in terminations for stopping points. Skim Coat: A thin layer of resin- or cement-based mo
