The cubic specimens with …
— The fineness modulus of sand used in ordinary concrete is 3.7-1.6, medium sand is suitable, and coarse sand plus a small amount of fine sand can also be used, and the ratio is 4 to 1. For natural sand, one fineness modulus can have multiple gradations.
Soundhirarajan ME and Valli [18] studied the change of concrete strength by replacing natural sand with artificial sand in quarry and believed that artificial sand in quarry was a good substitute. The above studies mainly focus on the working performance and mechanical performance of the RAC, artificial sand concrete, and polypropylene fiber RAC.

aggregate is called artificial sand . This paper present the physibility of artificial sand in concrete for the purpose of experimentation concrete mixes are design for m20 and m25 grades by 0 to 100 % with increment of 20 % replacement of natural sand by artificial sand. Compressive and tensile test are conducted to study the
One of the cheapest and the easiest ways of getting substitute for natural sand is by crushing natural stone to get artificial sand of desired size and grade [2]. The use of …
Table 1: Properties of Natural Sand 2.4 Artificial sand The artificial sand obtained from the local crusher was used. The physical properties of artificial sand are as below: Property Artificial Specific Gravity 2.90 Fineness Modulus 2.97 Bulk Density kn/m3 17.62 Zone II Table 2: Properties of Artificial Sand 2. Methodology
Concrete is a mixture of several materials. At the hardened state, this heterogeneous material becomes stone-like mass. The extensive use of concrete in the construction field has made it a material of huge concern for engineers. To participate in the vast uses of concrete an engineer must know its properties.
M. R. Chitlange in 2010 study shows that mixes with artificial sand as fine aggregate gives consistently higher strength than the mixes with natural sand. The sharp edges of the …

Let us consider the following concrete mix design example: A concrete with a specified compressive strength of 3750 PSI is required for a slab on ground. The slump should be between 3 and 4 inches, and the placement method is by pumping. The exposure conditions following the ACI 318-19 are briefly a follows: S1, F1, W0, and C1.

— Most studies related to artificial sand in civil engineering have focused on the comparison of strength property between natural sand-based concrete and artificial sand-based concrete [1][2][3] [4 ...
Regular testing and adherence to standards like those set by ASTM will guide you in selecting the right sand for your concrete mix. Benefits of using concrete sand. Using concrete sand in construction projects brings …
Cohesion is another thing that is important when we talk about sand. This means how much the sand sticks together. When sand is dry, it doesn't stick together very much. But when sand is wet, it can stick together and make shapes. The angle of repose is the steepest angle that sand can be stacked without it falling over.
— 2.1 Materials 2.1.1 Silty Sand. As shown in Fig. 1a, this work used the silty sand sampled from a foundation pit around the Yangtse River. The silty sand was passed through a 5 mm sieve to remove coarse grain soil particles (greater than 5 mm). The results showed negligible or even no coarse grain particles retained on the 5 mm sieve.
