When used as a stucco finishdifferent grades are usually mixed together to vary the size for improved strength and appearance. This specification covers natural or manufactured aggregate for use in job-mixed base and finish-coat ast thickness Portland cement, Portland cement-lime and modified Portland cement plasters.
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.
This abstract is a c879 summary of the referenced standard.
astn The sand is then graded from less than 2. The word “pound” in Spanish, Italian and Latin is “Libra”. What I am trying to say with all of this is that mortar can develop incredible strength by simply varying the grit of the sand, and using silica sand.
ASTM C – 00 Standard Specification for Aggregate for Job-Mixed Portland Cement-Based Plasters
Sand like Q-ROK is used in stucco finishes, but the grading is different. Imagine how strong other high abuse applications can be, such as mud floors, simply by spending a few bucks for graded silica sand. I know somebody out west who plasters boats.
ASTM C is sold in bags for about 11 dollars a 50 lb. Q-ROK is graded quartzite, which means crushed quartz or crushed white sandstone. Number two is all mediumand number 1 is all fine.
When used in a cement basecoat for asmt strength applications such as stucco floors or cement boats, the various grits can quadruple the compressive strength of Portland cement mortar. Fine powder is packaged as silica fines. 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.

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.
Silica sand usually crushed quartz or sandstone is passed through various screen sizes and measured as to the percentage of what size the grains are. Q-ROK comes in 3 grades, 1, or fine; 2, or medium and 3, coarse. The main difference is that number 3 is all the same size about 3 mm. Have you ever wondered why the word “pound” is abbreviated lb.
This chart is completely ambiguous if you do the math, but the idea is that the sand is graded from coarse down to fine powder. Also, since the sand is irregularly shaped, larger width particles can pass through the sieves.
