The study determined the strength of concrete mixture with sand and concrete mixture with sawdust in three different curing periods; 7 days, 16 days and 28 days. Experimental method was used by the researchers for it examined and investigated the possibility of using sawdust as a fine aggregate in concrete mixture with both mixtures categorized ...
Aggregates may be broadly classi fied as natural or artificial, both with respect to source and to method of preparation. Natural sands and gravels are the product of weathering and the action of wind or water, while manufactured crushed fine aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone.
Many artificial aggregates are either controlled, by-products of industrial processes, such as the various slags, or uncontrolled waste materials resulting from other industrial processes, such as clinkers and ashes. Another important source of waste material is the mineral extractive industry, including the extractions of coal and china clay.
Moreover, the replacement percentage increases the percentage difference up to 3.38%, 3.76% and 11.86%, respectively than natural sand strength (13) . In (15) studied, Msand (30% and 50% ...
Artificial fine aggregates with the particle size smaller than 4.75 mm were used for casting ECC. In order to keep the artificial fine aggregate sizes as the same, the particle size distributions of GPA and CBA were sieved and re-grouped to the targeted value (Table 4). FSS-ECC was also produced as a control group in this study.

Artificial Sand – A Short Overview. Artificial sand is one of the building sands' major constituents by crushing the concrete aggregates into potentially small-sized particles. It is mainly used in construction areas or industries where the availability of natural sand isn't possible.
The river sand in the Santo Tomas River area of the Philippines is a kind of volcanogenic sand. The sand is fine sand with a fineness modulus of 2.2, an apparent density of 2380 kg/m 3, a bulk density of 1320 kg/m 3, a mud content of 6.7%, a methylene blue value of 1.2, a soluble chloride ion content of 0.00071%, and a light-matter content …
In this research, the mechanical and durability properties of concrete with coral sand as a fine aggregate in partial replacement of river sand (30%, 40% and 50% by sand mass) is studied. The physical, chemical and mineralogical properties of the collected samples were studied. The hardened concrete specimens were subjected to compression and ...
2.2 Fine Aggregates. The fine aggregate used in this study was natural river sand and locally sourced. Its properties were checked as per IS: 383-2016 and IS: 2386-1963. It exhibited a specific gravity of 2.61, water absorption of 1.2%, and loose and compacted bulk density of 1580 kg/m 3 and 1602 kg/m 3, respectively. According to …

concrete using desert sand-doped artificial sand as the fine aggregate (DAS concrete) in this study are listed in Table 2, while the binder compositions are shown in Figure 2a. Besides the cement paste, the residual space in the concrete was occupied by the aggregate, including the fine aggregate (sand) and coarse aggregate (crushed stone).
The RCP artificial aggregates only require sealed storage and natural curing. The artificial aggregates are nearly spherical and exhibit good early strength performance. The compressive strength of each group reaches 75% to 92% of the 28d strength at 3d, and the compressive strength of a single particle reached 8.59 MPa at 28d.
Raw Material Selection:The artificial sand making process begins with the careful selection of raw materials. Typically, crushed rocks such as granite, basalt, or limestone are chosen for their hardness and durability. These rocks are then fed into crushing machines to produce coarse aggregates. Crushing and Screening:The coarse …
In addition, the use of artificial aggregates had marginal effect on the crack width distribution of high-strength ECC. The findings in this study demonstrate the feasibility of using artificial fine aggregates in ECC production and provide a new avenue to improve ductility and sustainability for ECC materials.
