Anotácia

This specification covers the requirements for aggregate-filled, resin-based, monolithic surfacing for use over concrete floors in areas where chemical resistance and the protection of concrete are required. The application methods for these floor surfacing shall include troweled, broadcast, slurry broadcast, self-leveling, sprayed, and reinforced. The resin chemistries include epoxy, urethane, polyester, and vinyl ester. Service conditions such as chemical exposure; traffic, and temperature conditions shall be considered in selecting the flooring system. The flooring material shall conform to the physical properties, chemical resistance, and performance requirements of the specific flooring system. The following methods shall be performed for the specific system to be tested: chemical resistance of mortars, grouts, and monolithic surfacing; test method for tensile strength of chemical-resistant mortars, grouts, and monolithic surfacing; test method for absorption of chemical-resistant mortars, grouts, and monolithic surfacing; test method for compressive strength of chemical-resistant mortars, grouts, monolithic surfacing, and polymer concretes; test method for flexural strength and modulus of elasticity of chemical-resistant mortars, grouts, monolithic surfacing, and polymer concretes; test method for determining the static coefficient of friction of ceramic tile and other like surfaces by horizontal dynamometer pull-meter method.
