Verification of Sealing Possibilities of Cement – Based Structures without Additional Surface Treatment

Verification of Sealing Possibilities of Cement – Based Structures without Additional Surface Treatment

Paper in proceedings (conference paper)

The paper introduces the results of research study aimed at sealing possibilities of cement-based substrates. The intention of the presented research is to verify whether the permanent and reliable seal in materials can be implemented even without additional surface treatment. The task is approached experimentally, using test procedures based on relevant European technical standards. The tested substrate is made up of glass-fiber reinforced concrete facade elements intended for the final cladding of buildings without any further surface treatment. The selected substrate is 13 mm thick, one test sample consist of two identical pieces of substrate connected by chosen sealant. A group of ten industrially-produced, commonly available sealants by three manufacturers is included in the experimental measurements. The research brought an answer to the question of the sealing possibilities of an unprocessed structures and also solved the issue of the most suitable type of sealant meant for this purpose.
