This company has a well-equipped laboratory unit for its productions. In the concrete admixture laboratory, the products are tested for quality and efficiency.
Shimisakhteman Concrete Admixture Laboratory is in addition to meeting the needs of the company as a standard fellow laboratory.
production and use of Concrete has around 100-year of history in Iran. With the development of various industries and urban development, the need for concrete has also grown dramatically. Only by mixing cement, gravel, and mineral aggregates you can not produce versatile concrete. Some concrete admixtures are essential to produce concrete with special characteristics. The Shimisakhteman has jumped forward to optimize this and has developed various admixtures to meet its needs. Manufacturing concrete admixtures for different usages and efficiencies requires research and testing on various compounds to produce the required product.
Shimisakhteman Company has various laboratories for its production. The concrete admixture Laboratory is one of the Shimisakhteman laboratories. By building a concrete laboratory, the company has taken an effective step in optimizing concrete. Currently, besides serving different industries, the factory’s concrete laboratory has close cooperation with the Iranian Standard Organization and the technical colleges and the Iranian Building Research Center and the Iranian Concrete Association.
Operation control in Shimisakhteman admixture Laboratory
1- Control of raw materials
All components of concrete admixtures are tested according to their usages. Approved products enter the manufacturing process if they meet the specifications of ISIRI 29930-1, 2930-2 and functional tests.
For all concrete admixture products, chemical tests are performed, Concrete is also randomly fabricated on the products according to the production tonnage.
Concrete admixture tests
Various tests are performed on manufactured products:
Uniformity – Colour – Effective Compounds by FTIR- Density – Dry matter content – PH – Total Chlorine – Water Soluble Chloride – Alkaline by mass by Flame photometer, Functional Admixture Testing Complies with all Tables 2930-2 Standard.
measurement of freshly mixed concrete Air content – Specific Gravity- setting time- water uptake by capillary Action-Determination of Slump and 1,7,28 Days compressive strength.
According to the tests mentioned above, produced control concrete and defined admixtures will go under experiment.
