ASTM-C811 › Standard Practice for Surface Preparation of Concrete for Application of Chemical-Resistant Resin Monolithic Surfacings (Withdrawn 2012)
The following bibliographic material is provided to assist you with your purchasing decision:
This practice provides for the preparation of concrete to receive resinous monolithic surfacing. The surfacing consist of fillers, resins, and hardeners which when properly mixed, applied, and cured, bond to primed or unprimed concrete. The monolithic surfacing may be either reinforced or unreinforced. The concrete should be designed to withstand all structural, thermal, mechanical stresses, and loading which will occur during service. The prepared concrete shall have a roughened appearance which is desirable for enhancing adhesion of the monolithic surfacing. It shall be similar to the texture of coarse sandpaper or to a roughness standard as established by the material manufacturer. Contaminated concrete shall be cleaned and neutralized. Methods of concrete surface preparation such as abrasive blasting, scarifying, acid etching shall be performed. As with other methods, the criterion of a clean strong concrete surface with good bonding profile must be maintained. Moisture, temperature, and concrete surface tensile bond strength tests for surface preparation of concrete shall be also be preformed.
Scope
1.1 This practice provides for the preparation of concrete to receive resinous monolithic surfacings. In these recommendations, the term monolithic surfacings includes toppings applied 60 mils (1.5 mm) in thickness or greater over concrete, which cure in place, are continuously bonded to the concrete surface, and provide a continuous surfacing.
1.2 The surfacings consist of fillers, resins, and hardeners which when properly mixed, applied and cured, bond to primed or unprimed concrete. The monolithic surfacings may be either reinforced or unreinforced.
1.3 This practice does not restrict the method of application.
1.4 This practice is intended for use with filled resin systems such as those covered by Specification C 722
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
