It is a proven fact that the concrete manufactured with M Sand performs better than concrete with river sand as the property of crush sand is better than that of natural sand. M-Sand is environmentally friendly as it replaces river sand. The cost of concrete made up of M-Sand is less than concrete made with River sand.
Sand is an important raw material in construction industry. It is the major fine aggregate. There is scarcity of natural sand in large scale because of increased sand mining in river beds leading to lack of natural sand reserves, urban expansion, local legislations and environmental constraints.
So here comparison is made between the compressive strength of concrete made with river sand and that made with quarry dust as fine aggregate in the production of concrete. 2.

When river sand is used in concrete, the permeability of concrete is lower than river sand. It has 2 to 4% more water absorption. The water absorption of river sand is less than 1.5 to 3%. Concrete with M sand has less deceleration than river sand. The slope of river sand is higher than that of crushed sand. There are no marine products involved.
Oct 21, 2020 A crushed sand is already sieved to 4.75 mm so that there is no wastage of it whereas river sand has more wastage. A setting time of concrete is faster when using with crushed sand compared to river sand. It doesnt contain silt but may contain some dust while river sand contains silt due to erosion of soil from its catchment area.
Concrete made up of M sand has very poor permeability compare to rive sand. River Sand permeability is better when added in concrete compare to m sand. M sand has water around absorption 2 to 4 %. Whereas, river sand water absorption is less than 1.5 to 3%.
This report deals with the comparison of the materialistic differences between sea and river sand. Chloride content in sea water X-ray diffraction pattern of crushed river sand powder
Feb 29, 2016 Higher concrete strength compared to river sand used for concreting. Lesser concrete compared to M Sand. Silt Content. Zero silt. Minimum permissible silt content is 3%. Anything more than 3% is harmful to the concrete durability. We can expect 5 - 20% slit content in medium quality river sand. Over Sized Materials.
Quality. We can expect a good quality of material since it is produced from a factory. The possibility of quality is low because sometimes other types of sand can be mixed with River Sand. Density. The density of M Sand 15540 to 1650 Kg/Cum. The density of River Sand 1400 to 1700 Kg/Cum. Impact on the Environment.
The crushed sand is manufactured from available rock stone, and the price will vary based on material availability. It can be produced near to the construction by the raw material. Due to the lack of availability, the price of river sand is high. Silt Content. In crushed sand, the possibility of silt content is less than 2%.
totally replaced river sand in the production of concrete. This work is focused on the use of quarry dust as a total replacement to river sand in the production of concrete, and comparing the results (compressive strength) to that obtained

Abstract This study compared the physical and mechanical properties of river sand concrete with quarry dust concrete. The constituent materials were batched by weight. The water-cement ratio and mix ratio selected for the experimental investigation were 0.55 and 124, respectively. The specimens were cured for 7, 14, 21 and 28 days. Slump, density and compressive

crushed limestone sand concrete compared with those of crushed granite sand concrete and river sand concrete. The test results showed that the fracture energy of con- crete was little influenced by the type of fine aggregate. In addition, the fracture energy of crushed sand concrete was slightly higher than that of river sand concrete. Also ...

Oct 24, 2017 Crushed stone, sand, and gravel can all be used as drainage aggregates. Drainage aggregates are either natural or processed, and coarse or fine. Coarse aggregate is typically larger than 5 mm in diameter, while fine aggregates are less than 5 mm. Base Layers.
Sep 02, 2021 Artificial sand, also called crushed sand or mechanical sand (m sand), refers to rocks, mine tailings or industrial waste granules with a particle size of less than 4.75 mm. It is processed by mechanical crushing and sieving. In China, the artificial sand was mainly used in the construction of hydropower systems.
for river sand. The performance of using manufactured sand (M-Sand) as fine aggregates with comparison to river sand and CRF in the production of concrete and mortar has been widely studied for years. It possesses intermediate angular particles and fines content in between those of river sand and crushed rock fines in general.
Apr 05, 2021 Crushed sand (CS) or manufactured sand has emerged as an alternate fine aggregate for the conventional river sand (RS) in many parts of India.
