The effect of artificial sand and crush sand as fine aggregate in concrete is to substitute the natural sand content in concrete. The experimental work is mainly concerned with the study of mechanical properties like compressive strength, split tensile strength and flexural strength of concrete by full replacement of natural sand by artificial sand as fine …

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. Two basic mixes were selected for natural sand to achieve M25 and M30 grade concrete. The equivalent mixes were obtained by replacing natural sand by stone dust partially and fully.

The machine has a screen that traps the larger material (that is, the crushed stone). The smaller material or "screenings" falls through the screen. Depending on the size of the holes in the screen used, it can …

1.Size of fine aggregates: The largest size that falls under the limit of the exact set is 4.75 mm. Using the largest size will give more dense concrete, but a mixture of all sizes is more desirable and more economical. If cement mortar is prepared for masonry work or plastering work, very fine types of sand of similar size is used.

gate and crushed stone as fine aggregate were tested at 7, 28, 56, and 90 days for various strength and durability characteristics of hardened concrete. Test results

This study determines the effect of Sulphuric acid on the compressive strength of concrete with Quarry Dust as partial replacement of fine aggregate at 0 %, 15 %, 25 % and 35 %. A total of seventy ...

The test results indicates the crushed stone dust can be used effectively to replace natural sand in concrete. In the experimental study of strength characteristics of concrete using crushed stone dust as fine aggregate it is found that there is increase in compressive strength, flexure strength and tensile strength. III. Materials Uses Cement

Materials. A high-early-strength Portland cement (ASTM Type III; 438 m 2 /kg Blaine fineness) was used. Coarse aggregate was crushed granite stone with a maximum size of 16 mm. A sulfonate melamine formaldehyde condensate superplasticizer, without chlorides, was incorporated in the concrete mixtures.

Many studies have examined the influence of the partial replacement of fine aggregate in concrete using crusher dusts or small crushed sand samples on concrete properties [8,12,13]. However, little work has been performed on the complete replacement of natural fine aggregate in concrete with crusher dusts.

The partial replacement of stone dust (40%) with fine aggregate has been verified by researchers [19], [20], [21]. The strength was enhanced up to 40% replacement level beyond what was seen in a decreasing pattern. At the same time, Singh et al. (2016) [22] achieved maximum strength at a 30% replacement level of stone dust with fine …

Fine Aggregate Meaning. Fine aggregates are usually sand or crushed stone that are less than 9.55mm in diameter. Typically the most common size of aggregate used in construction is 20mm. A larger size, 40mm, is more common in mass concrete. Larger aggregate diameters reduce the quantity of cement and water needed.

Aggregates comprise around 70% of concrete composition and are presented in two forms: (1) fine and (2) coarse. Fine aggregates are usually made of sand or crushed stone, whereas coarse aggregates can be up to 1.5 inches in diameter. One digs up sand or natural gravel from a lake, river, or seabed and then processes the …
