The field density test of soil is conducted in the field to know whether the specified compaction is achieved or not. Normally Sand Replacement Method is adopted for this purpose. Sand Replacement Method is also known as Sand Cone Method. The apparatus used in this field density test consists of a sand pouring cylinder, with pouring cone at its base.
The artificial sand produced by proper machines can be a better substitute to river sand. The sand must be of proper gradation (it should have particles from 150 microns to mm in proper proportion). When fine particles are in proper proportion, the sand will have fewer voids.
Sand in the future, it is very important to find Sand Alternate. The lack of sand directly affects the construction work. Many researchers are finding different materials to replace sand and one of the major materials is quarry stone dust. By the using of quarry stone dust make a proper mix of concrete with a satisfactory strength. In this research paper we use
12/04/2019#0183;#32;Sand is used mostly in mortar in all kinds of constructions. Sand plays a vital role in creating Bulk, Setting, Shrinkage, Strength and Surface Area of the mortar. Specifically; BULK Sand acts as an adulterant, increasing the bulk volume of mort...
21/09/2017#0183;#32;YesSubstitute of Sand in construction is also available that is known as MSand. MSand is also known as artificial sand. MSand is produced from crushing of hard granite stone. The crushed Msand is in cubical shape with grounded edges, washed and graded to as a construction material. The size of manufactured sand (MSand) is less than
Manufactured sand is sand produced by crushing rocks, quarry stones or larger aggregates pieces into sandsized particles. Natural sand, on the other hand is. Growing demand for fineaggregates in construction: as per EN13139. It can be used as a replacement or as a blended mixture with natural sand.
07/03/2019#0183;#32;Manufactured Sand or MSand or Man Sand obtained from crushing rocks in crusher plants to the size of sand particles. This can replace sand. Silica Fume obtained during production of ferrosilicon alloys from Iron. This can replace sand partially, not . More expensive than MSand, but can increase Flexural strength of cement concrete.
New study shows that plastic waste can replace sand in concrete. This change could lead to an environmental friendly solution in construction industry. Concrete is the most consumed material after fresh water as more than 20 billion tons are produced each year worldwide. The mixture of concrete consists of 30% of sand.
It is found that 40% replacement of sand by quarry dust gives maximum result in strength compared to normal concrete and then decreases from 50%. The results proved that up to 40% replacement of sand by the quarry dust induced higher compressive strength and the workability of concrete decreases as replacement increases.
Waste plastic could be used to partially replace sand in concrete to make construction more sustainable, according to research by the University of Bath. The research said it was possible to replace 10% of the sand in a concrete mix with waste plastic which had been ground down to similar sized granules as sand.
