(Specification)Standard Specification for Aggregate for Job-Mixed Portland Cement-Based Plasters
Standard Specification for Aggregate for Job-Mixed Portland Cement-Based Plasters
ABSTRACT
This specification covers natural or manufactured aggregate for use in job-mixed base and finish-coat full thickness Portland cement, Portland cement-lime and modified Portland cement plasters. Aggregate subjected to five cycles of the soundness test shall show a loss, when weighed in accordance with the grading of a sampling complying with the limitations set forth. The fineness modulus, friable particles, light constituents, organic impurities, material soundness, and sieve analysis of the aggregate shall be tested to meet the requirements prescribed.
SCOPE
1.1 This specification covers natural or manufactured aggregate for use in job-mixed base and finish-coat full thickness portland cement, portland cement-lime and modified portland cement plasters.
1.2 The values stated in inch-pound units are to be regarded as the standard. The SI (metric) values given in parentheses are approximate and are provided for information purposes only.
1.3 The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.
