USE OF CRUSHED STONE DUST AS A FINE AGGREGATE …
Stone dust obtained from granite stone quarry was used as the fine aggregate. Compared to sand, stone dust was finer with relatively lower fineness modulus. The developed comprehensive approach of proportioning normal weight concrete mixes1 was examined to enhance its applicability potential. Conventional control mixes, that is,
Review-Experimental Investigation on Quarry Dust as a …
The results of the test show that the stone dust can be effectively used in partial replacement of the total concrete in the concrete. It has been found that the use of stone dust increases the compressed and flexible strength of the concrete. The replacement level of the fine stone dust (30%, 40%, 50%, 60% and 70%) was checked by stone dust.
Experimental study on Use of Stone Dust as a Partial
