Abstract
Possibilities of the use of the secondary sodium nitrite in the construction industry, which is formed during production of nylon yarn at PTC “Khimvolokno”are considered. Analysis of literature is made. As a result additives are singled out, which belong to the group of antifreeze ones or to accelerators of hardening of concrete, which consists of substances, analogous to substances, which are part of secondary sodium nitrite. It is ascertained that secondary sodium nitrite can be used as antisleet reagent. Furthermore, introduction of secondary sodium nitrite into cement systems increases water demand of the cement paste, allows to change setting time of cement paste and increase the rate of curing of mortars in the initial period of hardening. It becomes especially apparent at hardening of mortars at low positive temperatures.
