M sand achieves better bond with cement than the round particles of natural sand. This is due to the reason that artificial sand contains sharp edged particles. Some studies prove that concrete made using M sand has 6% to 9% higher compressive strength and 12% to 15% higher flexural strength than river sand material of the same grade.
Concrete made from silica sand and artificial sand as fine aggregate was studied for compressive strength, Split tensile strength and Flexural strength. So in this project, Silica sand and artificial sand had been used as replacement of fine aggregate by different percentage for making concrete of M-30 grade, with w/c ratio 0.42.

The following are the major types of sand used in civil engineering: 1. River Sand: This type of sand is extracted from river beds and is commonly used in construction due to its smooth texture and fine grains. It is also known as natural sand and is free from impurities like clay, silt, and salts. River sand is widely used in concrete and ...
All particles larger than 0.19 inches are coarse aggregates but usually vary between 3/8 and 1.5 inches in diameter.Gravels make up much of the remaining coarse aggregate used in concrete with crushed stone.. Natural gravel and sand from a pit, river, lake, or seabed are normally mined or dredged.
The image above compares a mixture of concrete with natural sand vs. a mixture with artificial sand. With the slump test it is observable how the use of artificial sand impacts the performance of the mixture in the fresh state. It is possible to mitigate the negative effects of artificial sand with an air-entraining additive.
Chemical Composition of Sand. The primary chemical component of sand is silica, followed by smaller amounts of alumina, iron oxide, and calcium oxide. The chemical composition of sand is primarily SiO2, or silica. …
artificial sand should be promoted in the countries where need of fine aggregates are very high and on a very frequent basis When compared with the natural sand the properties are near similar but there is a very evident reduction in cost. In preliminary test …
Concrete sand, also known as sharp sand or coarse sand, is a type of sand that is commonly used in the construction industry for making concrete. It is designed to have …
artificial sand in comparison with the natural sand for producing concretes in an economical way. 1.2 DIFFERENT BETWEEN ARTIFICIAL SAND AND NATURAL SAND. Parameters M Sand River Sand Process Manufactured in a factory. Naturally available on river banks. Shape Angular and has a rougher texture. Angular aggregates demand more …
Currently, the river sand is becoming depletion leading to a rise in the price of construction material and issues related to the environment such as the depth of the river bed, lowering of the ...
Sand is divided into natural sand, artificial sand and renewable sand. Natural sand is formed by natural conditions (mainly rock weathering). The particle size below 5 mm is called natural sand. Artificial sand refers to the tailings or stone chips are produced during the processing of stone ore and block stones, then washed and sifted.
It was observed the results have shown positive changes and improvement in mechanical properties of the conventional concrete due to the addition or replacement of fine sand …
Noncorrosive reinforcement materials facilitate producing structural concrete with seawater and sea sand. This study investigated the properties of seawater and sea sand concrete (SSC), considering the curing age (3, 7, 14, 21, 28, 60, and 150 d) and strength grade (C30, C40, and C60). The compressive behavior of SSC was obtained by …
