As mentioned earlier, rock dust may be a promising alternative for fine aggregate in mortars and concrete. These inert fillers, which may be composed of rock of different geological origin from the grinding process, can be used to enhance both particle size distribution and packing density.
Relative density (specific gravity) is also used in the computation of voids in aggregate in Test Method C29/C29M. Relative density (specific gravity) (SSD) is used in the determination of surface moisture on fine aggregate by …
Quality of Granite Fines: To select Granite Fines from a reliable sources, its quality shall comply with requirements of SS EN 12620 as well as the requirements in section 3, 4 and 5 of this guideline with limit of fine content below 16%.
Granite dust is regarded as a valuable and easy-to-obtain alternative for customary, natural fine aggregate. However, granite dust can be employed in engineered cement composites (ECC). Nevertheless, multiple health and environmental hazards are attributed to it, due to the fact that it is a non-biodegradable material. The current study, …
Aggregates are granular materials used either as underlying materials for foundations and pavements or as skeleton structure and filling in Portland cement concrete and asphalt mixture. The physical properties, mechanical properties and gradation of aggregates have significant impacts on the performance of infrastructure. This chapter …
The fine aggregate specific gravity test (Figure 1) is used to calculate the specific gravity of a fine aggregate sample by determining the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. It is similar in nature to the coarse aggregate specific gravity test.
This Bulletin describes types of aggregates normally used in concrete, aggregate properties affecting performance of the concrete, tests used to measure aggregate properties, and methods used to obtain test samples. Normalweight as well as lightweight aggregates are discussed.
Bulk density of concrete reduced as replacement percentage for sand increased; for coarse aggregates gravel gave the highest value of 2479kg/m 3.
In this study, seven grain size ranges of granite fines were used: 4.75 3.35mm, 3.35 2.36mm, 2.36 1.70mm, 1.70 1.18mm, 1.18 0.30mm, 0.30 0.063mm and 4.75 0.063mm (those containing all grain sizes). The properties considered for the investigation are compressive and flexural strengths, density and workability. Four mix proportions of …
higher dosage of superplasticizer was needed in concrete with fine sand to overcome the adverse. effect of fine materials. A similar behavior was observed in the other mixtures containing granite ...
Completely decomposed granite (CDG) soil is a typical and abundant in-situ weathered soil on the ground around the world. This paper investigates the possibility of CDG soil as fine aggregates for production of Portland cement concrete.
The gradation and size test (Figure 1) is used to determine aggregate particle size distribution. Size distribution is perhaps the single most important aggregate quality associated with the control of HMA mixtures. Aggregate gradation and size affect HMA volumetric properties as well as mixture permeability and workability.
IJSRSET151621 | Study on Strength & Durability of Concrete by Partial Replacement of Fine & Coarse Aggregates using Marble, Granite & Spent Fire Brick Waste
The results obtained show that the incorporation of granite sand up to a rate of 20% improves the compressive strength and the resistance to acid CH3COOH. For concretes made with tiling sand, the ...
Hence from socio-economic concern, granite dust can be utilized in construction applications due to its appearance and particle size distribution nearly similar to natural aggregates. In this research work, experimental analysis of physical, mechanical properties of granite dust replaced concrete and bond strength was conducted.
The mechanical characteristics of concrete made with steel slag as a cementitious material and coarse aggregate has been the focus of research. Only a few studies, particularly on fly ash-based geopolymer concrete, have looked at concrete with a significant intensity of steel slag as a fine aggregate.
The density of granite is between 2.65 and 2.75 g/cm 3, similar to sand and compressive strength will be greater than 200 MPa. Granite fines are used as a filler material in the concrete, replacing the fine aggregate which will help in filling up the pores in the concrete and increase the strength of the concrete.
Laterite was used as fine aggregate, while granite of 20 mm nominal size was used as coarse aggregate. Compressive cube strength and saturated surface dry (SSD) bulk density tests were conducted.
A. Procedure for Compacted Bulk Density. Measure the volume of the cylindrical metal measure by pouring water into the metal measure and record the volume "V" in litre. Fill the cylindrical metal measure about one-third full with thoroughly mixed aggregate and tamp it 25 times using tamping bar. Add another layer of one-third …
Grading Limits for Fine Aggregates. (Based on Clause 4.3 of IS: 383 - 1970) Grading of aggregates are determination of particle size distribution of aggregates. Grading of …
In density, basalt have a density of 1554.55kg/m3 while granite had a density of 1463.64kg/m3. Aggregate impact test conducted on both aggregates revealed a percentage of 11.05% for basalt and 12. ...

The addition of granite powder along with the ceramic coarse aggregate improves the mechanical properties of concrete slightly since mineral and chemical properties are of granite. The split tensile strength of ceramic tile aggregate is very much in a straighter path compared to the conventional grades of concrete.
