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.
