Service reliability of sealants in canal facings
Conclusions 1. The lack of objective criteria for estimating life in the case of accelerated aging necessitates periodic laboratory and stand tests of sealants extracted from full-scale joints. 2. It is recommended to seal compressed joints by Poroisol-type seals; glued reinforced sealants are effective for joints of sectional facings of canals, and especially when repairing and reconstructing facings. 3. A high quality of sealing is secured in embedded-type joints. In sectional and monolithic facings of canals with the use of Hydrom and KM-0.5 types of Thiokol mastics, which are subject to displacements in the structures during service, it is recommended to use STS-41 fabrics as reinforcement. 4. It is not recommended to use polyester resins of type PN-1, polyester mastic, bituminous modifications, and butylphenol formaldehyde resins as glues in joints subjected to the prolonged action of water. 5. The experiment of water management construction showed that the use of polymers in place of the traditional materials increases the quality of sealing, thereby promoting an increase of service life and decrease of cost of faced canals [10].
