The manufactured sand has an essential gradation of fines, physical properties such as shape, even exterior touches, and constancy which kinds it the greatest sand appropriate for construction. These physical properties of sand provide greater strength to the concrete by decreasing separation, bleeding, honeycombing, voids, and capillary.
Accordingly essential grade of sand for the assumed determination helps the concrete fill voids amongst coarse aggregates and marks concrete added compact and dense, therefore increasing the strength of concrete.
In the meantime, processed sand (M-Sand) is treated with the designated excellence of granite and has durable physical and chemical properties for the building of concrete structures.
This feature of M-Sand allows the concrete structures to experience very environmentally sustainable conditions and prevents the weathering of reinforced steel by reducing permeability, moisture ingress, freezing-thaw effects of improving the longevity of concrete structures.
Scale, form, touch plays a crucial role in the workability of the concrete. Due to the extra surface area of sand, the order for cement and water growth is made to guarantee sand with rough aggregates.
The controller of these physical properties of the manufacture of sand marks the concrete that requires less water and delivers advanced workable concrete. Less use of water also helps from improving the consistency of concrete, less time to blend and settle the concrete, and thus improves the productivity of on-site building operations.
Construction defects in the placement and post-concretion, such as separation, bleeding, honeycombing, voids, and capillarity in concrete, are minimized with the use of M-Sand, as it has the highest original and final set time as well as excellent fineness.
Use of M-Sand has enhanced reliability, increased resilience, decreased isolation, permeability, improved workability, reduced post-concrete defects, and has seen to be cost-effective as a building material that replaces river sand.
In many instances, the expense of transporting river sand may also be saved.
The use of engineered sand avoids the dragging of river beds through river sand that could contribute to environmental disasters such as soil water pollution, water shortages, danger to the stability of bridges, dams, etc. to make M-Sands more eco-friendly than river sand.
The outline of Crushed sand is cubicle and angular and has a rugged feel and is thus better for concrete.
It does not contain silt when it is produced by grinding aggregates, although if the screening is not correct, it will often contain any dust.
It does not contain any moisture.
When used in concrete, the settling time of concrete is relatively quick.
The compressive strength and flexicurity of the concrete made of m sand is stronger than the natural sand.
When used as asphalt, the permeability of concrete is very low relative to the sand of the river.
Made artificially, but there are no oversized materials.
Water absorption of crushed sand is between 2 and 4 per cent.
The slump of crushed sand is smaller than the slump of reverse sand.
It does not include aquatic material.
The bulk density of crushed sand is 1.75 g/cm3.
The basic gravity of the crushed sand is 2.5 to 2.9 which varies on the parent rock.
There is no need to correct bulking during the mixing design by using Crushed Sand in concrete.
Ability of old surface moisture Crushed sand is up to 10%.
It has less adulteration than the sand of the river
It does less harm to the atmosphere than to real sand.
It is of higher quality than natural sand since it is produced in a managed climate.
It can be manufactured in the vicinity of the building site. Reducing shipping costs and providing and guaranteeing a steady supply.
It is strongly recommended that RCC work on brickwork as well as blockwork.
It's affordable than sand. The amount of crushed sand is roughly 1000 per cubic metre.
It does not contain an organic and soluble compound that influences the timing and properties of the cement and thus the necessary strength of the concrete can be preserved.
The presence of impurities such as mud, dust, and silt coatings does not increase the water demand, as in the case of river sand, which impairs the bond between cement paste and aggregate. Increased consistency and longevity of concrete.
M-Sand is collected from real hard rock (granite) using state of the art international technologies, thereby obtaining the necessary sand property.
M-Sand is cubic in shape and is produced using technologies such as high carbon steel hit a rock and then ROCK ON ROCK operation, which is synonymous with the natural process of river sand information.
Modern and imported machines are used to manufacture M-Sand to maintain the appropriate sand grading field.
The workability of the M sand generated concrete is less than that of the natural said make. But this can be maintained by using a water-reducing mixture (Superplastsizer).
The form of the sand of the river is rounded and has a flat finish. Apart from the form of M sand is a cubicle and Angular and has a rough texture due to this cement paste used to fill holes in concrete made using river sand is less than M sand. As a result, m sand needs more water and cement to reach the expected workability contributing to higher costs.
The other drawbacks of M sand are that m sand produces greater quantities of micro-fine particles than natural sand in its manufacturing phase. Again, this will impair the quality and durability of the concrete.
River sand, naturally available, has moisture stuck in its particles, which is needed for good concrete. In the other side, only M-Sand washed water preserves moisture.
Due to its high demand, there are cases of M-Sand being adulterated with extraneous materials such as quarry mud.
To confirm M-Sand is of the uppermost quality, it’s powerfully directed to put it finished a sequence of quality tests such as
Greater Durability: M-Sand has balanced physical and chemical properties that can withstand any aggressive environmental and climatic conditions as it has enhanced durability, greater strength, and overall economy. Usage of M-Sand can overcome the defects occurring in concrete such as honeycombing, segregation, voids, capillary, etc.
High Strength: The superior shape, proper gradation of fines, smooth surface texture, and consistency in production parameter of chemically stable sands provides greater durability and higher strength to concrete by overcoming deficiencies like segregation, bleeding, honeycombing, voids, and capillary.
Greater Workability: The crusher dust is flaky and angular in shape which is troublesome in working. There is no plasticity in the mortar which makes it even difficult for the mason to work, whereas the cubical shape with grounded edge and superior gradation gives good plasticity to the mortar providing excellent workability.
Offsets Construction Defects: M-Sand has optimum initial and final setting time as well as excellent fineness which will help to overcome the deficiencies of concrete such as segregation, bleeding, honeycombing, voids, and capillary.
Economy: Usage of M-Sand can drastically reduce the cost since like river sand, it does not contain impurities and wastage is NIL. In International Construction Scenario, no river sand is used at all, only sand is manufactured and used, which gives superior strength and its cubical shape ensures a significant reduction in the cement used in the concrete
Eco-Friendly: M-Sand is the only alternative to river sand. Dredging of river beds to get river sand will lead to environmental disasters like groundwater depletion, water scarcity, a threat to the safety of bridges, dams, etc.
Silica (SiO2): M-sand is primarily composed of silica, which is the main component of sand. Silica content in M-sand is usually high, ranging from 80% to 99%. Silica provides strength and durability to the construction materials.
Alumina (Al2O3): M-sand may contain a small amount of alumina, typically less than 10%. Alumina can influence the setting time and workability of concrete.
Iron Oxide (Fe2O3): M-sand may contain traces of iron oxide, which can impart a reddish color to the sand. However, the iron oxide content is generally low.
Lime (CaO): Lime content in M-sand is usually minimal. It is present in the form of calcium carbonate and may contribute to the alkalinity of the sand.
Magnesia (MgO): Magnesia content is typically low in M-sand. It can affect the setting time and strength development of concrete.
Potassium Oxide (K2O) and Sodium Oxide (Na2O): M-sand may contain traces of potassium and sodium oxides, which are usually present as impurities.
Consistent Quality: M-sand is manufactured under controlled conditions using advanced technology, ensuring consistent quality and properties.
Better Shape and Gradation: M-sand has a well-graded particle size distribution, which means it contains particles of various sizes. This results in better packing and improves the workability of concrete and mortar.
Lack of Natural Binding Properties: Unlike river sand, M-sand does not have natural binding properties. It may require the addition of chemical admixtures or other additives to improve the bonding between particles and enhance the workability of concrete.
Higher Cost: In some regions, M-sand can be more expensive than river sand due to the costs associated with manufacturing, transportation, and quality control. The availability of M-sand may also be limited in certain areas, leading to higher prices.
