Conclusions
-
1.
The technology of sealing with the use of grouts with an adjustable fluidity loss time (GAFLT), developed at Gidrospctsproekt and successfully introduced on the construction of the Inguri arch dam, is universal and makes possible high-quality grouting of joints with a high degree of their leakiness.
-
2.
The new technology has indisputable advantages over the existing technology. It provides a high quality of the work and is cost effective, enabling a substantial reduction of labor expenditures and nonproductive losses of cement.
-
3.
The GAFLT technology can be recommended for inclusion in building codes and can be used when scaling concrete dams under construction.
