A principle point to mention is that our silica have a spherical shape and this brings the depreciation of the nazzel and the hose of the lowest.

By the way, we are certified by Sarcheshmeh Copper and Alloy Steel complex and south Oil-Bearing regions.


 

 

 

 

 

 

•  cement mortar

As it was mentioned before the silica sands are used for cement mortar lining treatments in great water distribution systems throughout our country.

The most important privileges of these sands is that they are natural and decrease largely depreciation the concrete pump and concrete carrying equipment. In addition the fine surface with low coarseness of the sands provides a high compressive strength so that the C in Hazen-Williams formula is 125.

The internal lining of water pipes through cement mortar method and quality of consuming sand in accordance with universal standards such as AWWA, ISO 4179, API.BS is of a great importance and we introduce our sands the material of choice for water distribution projects.

•  Concrete

Laboratory test reports indicates the accordance of our sands with the 302 national standard for making concrete.

The physical specifications of these sands are:

•  Grading

Sands grading is constant and less than 2 percent passes NO.200 mesh and is accordance with ASTM and BS standards.

•  Sand fineness modulus ( f.M )

The fineness modulus must be vary from 2.3 to 3.1 according to the technical and general specifications of building process and ours is about 2.5

•  Sand equivalence value

It's higher than 93% that varies depending on the customers order

•  grouting
