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.

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).
