Utilization of Industrial Waste Water Treatment Residues in Alkali Activated Cement and Concretes
The paper discloses an effective way of utilization of industrial waste water treatment residues. The wide use of industrial waste water in building materials is difficult due to the presence of heavy metal. However, alkali activated cements showed high ability of immobilization of heavy metals. The compressive strength of AAC systems with water treatment residues (galvanic process waste water) is up to 40 MPa in mortars and 45 MPa in concretes. The leaching behaviour of heavy metals from the cements matrix after soaking up to 28 days was also examined with AAS.
