WP - Wietersdorfer & Peggauer Zementwerke GmbH, Klein St. Paul, Austria
Wietersdorfer & Peggauer Zementwerke GmbH (w&p) is part of the „Wietersdorfer Gruppe“ and producer of cement, lime and other binding materials as well as premixed dry and wet mortars. Cement production in Wietersdorf has been started about 115 years ago, so there is a long tradition and experience in that field in the company. At present, W&P has got three production sites in Austria, namely Wietersdorf (cement, premixed dry and wet mortars), Peggau (cement, lime and premixed dry mortars) and Leoben (premixed dry mortars).
Within the company, different types of technology are used for the production of various binding materials. The Wietersdorf plant is equipped with a dry kiln for clinker production, whereas a so called Lepol kiln is used for clinker production in Peggau. Lime production in Peggau is presently performed using a shaft kiln and an annular shaft kiln, another type of kiln is under construction. Besides, there are several mills for grinding the burnt material to suitable grain size when necessary. This shows that the participation of W&P offers a wide range of production facilities for the scale up of the production of Roman cement to an industrial level.
There are laboratory facilities in each of the production plants, which are used for both product development and control of production. The apparatus includes for example XRF, XRD and ICP. Besides we are equipped to do wet chemical tests. Physical tests include for example granulometry, penetration, flow, setting times, flexural strength, compressive strength and elastic modulus.

Dr. Eva Wolf-Haslinger will be responsible for the coordination of the W&P activities within the project. She studied chemistry at Graz University of Technology and received her doctoral degree in 1990. From 1985 she was doing research work at the Institute for Analytical Chemistry, Micro- and Radiochemistry of this university with a focus on XRF trace element determination from geologic material for geochemical purposes. 1992 she left university and changed to W&P, where she has been responsible for the cement laboratory in the Peggau plant at the beginning. At present she is responsible for quality management and R&D on lime products within the company. Thus she has got more than 15 years experience in cement and lime industry meanwhile. Being Austrian member of WG 11, a working group of CEN TC 51, she is contributing to standardisation of building lime.
Role in the Project
The principal role of W&P within ROCARE is to burn Roman cement from various raw materials using different kiln types, scaling up to and optimizing the production. The burnt material will be ground to adequate grain size for use. Quality and production control will be carried out during and after the production process and will include analysis of the material composition, granulometry, setting times, soundness and strengths for instance. The Roman cements prepared in this first step (WP1) will be used as binders in different mortars in a second step (WP2).
