| Use advice for data set | Scope: Within this study a life cycle analysis according to ISO 14040/44 is performed for Çimsa RECIPRO40 ® - Calcium Aluminate Cement produced by Çimsa Çimento San. ve Tic. A.Ş. at the production plant located in Mersin. This analysis relies on transparent, plausible and documented basis data. All the model assumptions, which influence the results, are declared. The life cycle assessment is representative for the products introduced in the declaration for the given system boundaries. The life cycle assessment covers the manufacturing of the products from cradle to gate. System boundary: Type of EPD: cradle to gate The system boundary includes the production of Çimsa RECIPRO40® Calcium Aluminate Cement from extraction of raw material to the production of finished packaged product at the factory gate (cradle to gate). In this study, the product stage information modules A1, A2 and A3 are considered. These modules include raw material extraction and processing (A1), transport of the raw materials to the manufacturer (A2), manufacturing of the product which includes raw material mixing and grinding, preheating, firing and cement grinding (A3), energy and water consumption, waste management, air and water emissions from processing and energy combustion (A3), and the packaging of the product for final delivery (A3). The construction stage, the use stage and the disposal stage are not included in the life cycle assessment of RECIPRO40. |
| Technical purpose of product or process | The main uses of RECIPRO40 are for the manufacturing of building chemicals, refractory and precast products. It offers high early strength and controllable setting time which are important features for building chemicals producers. Another important use is inner plating of sewage pipes in the precast form where resistance to acid and sulphate attacks is paramount. Due to its high alumina content, RECIPRO40 can resist up to 1300 °C. Therefore, it presents an economic and viable solution for the industrial floorings that requires high temperatures. |

| General comment on data set | The declared product is Çimsa RECIPRO40 - Calcium Aluminate Cement (RECIPRO40) manufactured in accordance with /EN14647/. RECIPRO40 is defined under the special cement class. Calcium aluminate cement is composed of hydraulic calcium aluminates as main constituent. Cement is the adhesive or glue which, when sets, binds particles of fine aggregate together to produce mortar. When mixed with water the cement forms a paste called the fine matrix. Cements are hydraulic materials, this means that they depend upon a reaction with water rather than air for strengthening. When water is added to cement a chemical reaction called hydration commences immediately. The reaction continues while water is still present. After hardening, it retains its strength and stability even under water. |

| Technology description including background system | For calcium aluminate cement, the production starts with the transport of raw materials to the production plant. Already crushed materials are then sieved and fed to the kiln. In the L-shaped kiln the clinker production takes place at around 1600-1700°C. Then, the clinker is cooled and transferred to the cement grinding mills. The final product is sold as bagged or bulk cement. The basic materials for the production of calcium aluminate cement clinker consist of calcium oxide (CaO), silicon dioxide (SiO2) and small amounts of aluminum oxide (Al2O3) and iron oxide (Fe2O3). Raw materials that provide these constituents are limestone and bauxite as its natural occurring mixture. Technical data: RECIPRO40 is a calcium aluminate cement which is classified under the special cements. With its 6 and 24 hours of high strength values, it has the strength that is much higher than the Portland Cement in accordance with /EN 197-1/. Declared unit: The declared unit is 1 t of Çimsa RECIPRO40 ® - Calcium Aluminate Cement. |
