Manufactured Sand and Aggregate
Alternate for River Sand
This sand is manufactured according to the specifications of ISI2116-1980-2.0
and IS: 486:2000 and IS: 383:1970.
The particle shape is semi rounded or cubical and not flaky or elongated.
The percentage of dust is strictly controlled
|
Manufactured Sand [ Brand
Name : CHETAK |
|
|
|
Contains
no organic Impurities, hence it gives increased strength of Concrete with same cement content. |
|
|
|
Gradation
of sand is controlled in the manufacturing process; hence mix design can be accurately used due to consistent gradation. |
|
|
|
No
wastage since Sand is already sieved in the required size (below 4.75 mm). |
|
|
|
Consistency
in supply as well as stability in prices helps in controlling the project cost. |
|
|
|
Does
not harm the environment in any way |

NOTE:
The test and Mix design were conducted strictly as per procedure given in current Indian Standard Specification.
Any Changes
in material characteristics as well as in mixing, batching, and curing method are likely to alter the mix properties.
Production
and control of concrete should be strictly in accordance with Indian Standard Code of practice for plain and reinforced concrete.
|
Quality Assurance |
|
|
Cube testing for every 5000 MT Production |
|
|
Strict Sizing control by controlling the machine's parameters |
|
|
Field trials are taken at customers site once a Month or as requested as a part of after sales service |
Please note that our crushers are located in INDIA.
