was studied with various proportions of quarry dust (CM 1:3, CM 1:2, and CM 1:1). The experimental results showed that the addition of quarry dust for a fine to coarse aggregate ratio of 0.6 was found to enhance the compressive properties as well as elastic modulus. Key words: Concrete, quarry dust, fillers, elastic modulus, compressive strength.

The influence of the stone dust content in sand on mortar properties are presented in this paper. Three stone dusts (quartz, granite and limestone) were incorporated in percentages ranging from 0 to 20% as replacement for equal weights of sand. ... and the fineness modulus decreased to 2.85, 2.70, 2.57 and 2.42 for 5, 10, 15 and 20 % of dust ...
Stone dust was processed in two forms one for replacement of sand and another for cement replacement. For sand replacement the gradation and fineness modulus of stone dust was kept similar to the ...
aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone. Crushing, screening, and washing may be used to process aggregates from either sand and gravel deposits or stone quarries. Aggregates may be produced from igneous, sedimentary, or …
The suitability of crushed stone dust waste as fine aggregate for concrete has been assessed by comparing its basic properties with that of conventional concrete made with natural sand ...
Stone dust, as the name implies, is relatively fine dust created by running stones through a crusher machine. Stone dust can be made out of many different kinds of stone, although granite is a very popular option. This is the only thing that stone dust contains, and it does not contain any kind of binders. This material does not bind or adhere ...

However, the comparison of configurations F, G and H shows that at high fines content (i.e., 12%) the response is different. A sample with lower dust ratio (i.e., F) shows a Range C type material behavior and a sample with higher dust ratio (i.e., H) results in Range A. Configuration G with DR of 0.6 shows a behavior in between these two limits.

Therefore, fineness modulus of coarse aggregates = sum (cumulative % retained) / 100 = (717/100) = 7.17 Fineness modulus of 7.17 means, the average size of particle of given coarse aggregate sample is in between 7 th and 8 th sieves, that is between 10mm to 20mm. Limits of Fineness Modulus Fineness modulus of coarse aggregate varies from 5.5 to 8.0. And for all in …

What is Fineness Modulus of Aggregate? Fineness modulus is an empirical factor obtained by adding the cumulative percentages of aggregate retained on each of the standard …
The cement concrete stone dust CCSD 7.5 with partial replacement of 7.5% stone dust shows an increase in compressive and flexural strengths of 14.42% and 15.85% at 28 and 56 days as compared to the nominal mix, respectively. The increase in strength is due to the dense microstructure of the specimen in the presence of fine crushed stone dust ...
Test for grain size analysis or sieve analysis of aggregates are done to determine its particle size distribution, fineness modulus, effective size and uniformity coefficient. Fine aggregate is the …
Physical properties like specific gravity, fineness modulus etc. of stone dust and fine aggregate should be comparable in order to use stone dust as a replacement of fine aggregate. Studies …
The fineness modulus of a fine aggregate is defined as an index number that indicates the average or mean size of the sand particles. It is determined by carrying out the sieve analysis test using standard IS sieves. The fineness modulus is an estimate of the amount of aggregate required to proportion mix designs; it is not a precise measurement.
Sand equivalent value and dust content and fineness modulus are shown in Table 2. The term "sand equivalent" expresses the concept that most granular soils and fine aggregates are mixtures of ...
