A company located in southern Poland is looking for a technology suitable for production of raw material for casting of semi-finished products based on limestone dust. The company is looking for a partner interested in wide co-operation, such as manufacturing agreement, license agreement or joint-venture agreement.

A Polish SME located in the Kielce region is looking for a production technology of cast products (prefabricated units) from light limestone discards (in milled or crushed form), including addition of appropriate binding agent. In liquid form, the product must be suitable for casting in various kinds of moulds, and after drying it shall have properties (mainly strength and absorbability) close to those of the limestone constituting the main slurry component.

Technical Specifications / Specific technical requirements:
Physical and chemical properties of limestone rock:
- Compressive strength in saturated condition: 9.4 MPa
- Compressive strength after freeze resistance tests: 5.8 MPa
- Standard absorbability: 11.2 %
- Freeze resistance (25 cycles) - without any damage
- Volume density: 1.7 g/cm3
- Density: 2.67 g/cm3
- Porosity: 28.6
- Coefficient of thermal conductivity: 0.434 kcal/mhoC
Chemical composition: CaO - 52,36%; SiO2 - 3,17%; TiO2 - 0,2%; Al2O3 - 0,27%; Fe2O3 - 0,23%; MnO - 0,005%; MgO - 0,73%; Na2O - 0,17%; K2O - 0,08%; P2O5 - 0,245%; SO3 - 0,04%; Cl - 0,009%; F - 0,19 %
