Abstract. A constant trend in recent decades has been the tightening of environmental requirements for production and finished products. In turn, in the development of the building materials industry, the issues of producing new types of innovative building materials, reducing the negative impact on the environment, and involving waste in their production are relevant. In recent years, many scientific teams have been conducting active research work related to the involvement of soda production waste as a raw material component in construction compositions. This type of waste accumulates in fairly large quantities, and its storage method requires large areas and high costs. Soda production waste is a mineral product consisting mainly of calcium carbonate and sulfate. This predetermines its use as a modifying component that helps increase the water resistance of liquid glass building compositions. The authors of the work experimentally confirmed the effectiveness of modification with a calcium-containing mineral product in the form of soda production waste. It was revealed that the modifier does not have a destructive effect on the liquid glass system. The induction period of hardening of the raw material mixture with a rational content of finely dispersed soda product is 55–80 minutes, defining the liquid-glass composition as very technologically advanced. It has been established that with the introduction of a finely dispersed waste additive in an amount of more than 10 % by weight of the binder, the increase in the water resistance of the samples is about 20–30 %. The authors of the work assessed the environmental and sanitary-hygienic safety of using soda production waste when designing recipes. It was established that the waste sample is slightly toxic and classified as hazard class 4. Based on the specific effective activity indicator, its radiation safety has been established.

Keywords: construction liquid glass compositions; liquid sodium glass; calcium-containing modifier; soda production waste; water resistance; hazard class; radiation safety
