Scrape or wear away by friction.
Wearing away by friction.
Ability of a surface to resist being worn away by rubbing or friction.
The amount of water absorbed when a material or product is partially immersed for one minute; usually expressed in either grams or ounces per minute per 30 sq. in; also called suction or initial rate of absorption.
A substance which, when added to concrete, mortar, grout, or plaster, increases the rate of hydration of the hydraulic cement, shortens the time of setting, or increases the rate of hardening of strength development, or both; materials used to speed up the setting of mortar or concrete.
Acetone is a good solvent for most plastics and synthetic fibres including those used in laboratory bottles made of polystyrene, polycarbonate and some types of polypropylene. It is ideal for thinning fiberglass resin, cleaning fiberglass tools and dissolving two-part epoxies and superglue before hardening. It is used as a volatile component of some paints and varnishes. As a heavy-duty degreaser, it is useful in the preparation of metal prior to painting; it also thins polyester resins, vinyl and adhesives.
Acid etching involves allowing the reaction of a dilute solution of hydrochloric acid to the concrete surface, then rinsing off with water. The acid chemically reacts with surface laitance, dissolving it and allowing it and other water-soluble contaminants to be washed away.
A substance added to another to impart different or special qualities; an admixture.
The state in which two surfaces are held together by interfacial forces which may consist of valence forces or interlocking action, or both; bonding strength; the attraction of a coating to the substrate.
The state in which two surfaces are held together by interfacial forces which may consist of valence forces or interlocking action, or both; bonding strength; the attraction of a coating to the substrate, or of one coat of paint to another. 2. The soil quality of sticking to buckets, blades, and other parts of excavators.
A decorative timber moulding around openings, windows and doors.
AS 3740-2004 : Waterproofing of wet areas within residential buildings. This Standard sets out requirements for materials and minimum design and installation criteria for the waterproofing of wet areas within residential buildings. It includes typical details of construction materials and methods. It does not cover situations where flooding of the wet areas occurs through overflowing of vessels and showers or plumbing failures. Notes: 1 Appendix A provides guidance on means for compliance with this Standard. 2 Appendix B provides design considerations for wet area waterproofing. Supersedes: DR 02124 Waterproofing of wet areas within residential buildings. AS 3740-1994 Waterproofing of wet areas within residential buildings.
