In article results of researches of influence of type and concentration of various electrolytes on the rheology of clay suspensions. The influence of liquid sodium glass, sodium carbonate, sodium tripolyphosphate and lignin-alkaline reagent on the fluidity of the clay slurries. It is shown that the use of a number of electrolytes at low concentrations increase the mobility of clay suspensions. Found that when using polymineral clay vladimirovskaya the greatest thinning effect was achieved with the introduction of the sodium silicate glass.

The use of a dry waterproofing compounds can significantly improve the protection of structures of buildings and structures from moisture. In determining the reliability of operation of construction projects is the choice of waterproofing material. To protect the structures used, penetrating, plastering and waterproofing obmazochnoy, depending on the specific operating conditions and design features of buildings. The use of a dry waterproofing compounds opens up opportunities for the waterproofing.
