Abstract
This research deals with the use of liquid glass in industry particularly for porous filler production. The aim of this paper is to show the necessity liquid glass modification for the purpose of its rheological characteristics change for raw granules formation and providing given structure after porization. Data on chemical liquid glass modification are provided by adding sodium chloride. Moreover, inert mineral additives influence on porous filler properties are shown in this paper. The basic principles of light concrete composition selection are specified. Test results of light concrete on the developed porous sodium silicate filler are given.
Highlights
The aim of this paper is to show the necessity liquid glass modification for the purpose of its rheological characteristics change for raw granules formation and providing given structure after porization
Water solution of sodium silicate is generally obtained in the process of high pressure steam treatment of silicate lump and water [1,2,3]
In Russia water solution of sodium silicate is better known under the trademark "liquid glass" or "soluble glass"
Summary
Water solution of sodium silicate is generally obtained in the process of high pressure steam treatment of silicate lump and water [1,2,3]. It is like transparent viscous liquid having density 1200-1500 kg/m3 and high adhesive properties. There is one more name – "Fuchsian glass" named after the developer of liquid glass industrial technology – J.N. Fuchs [1]. Abroad, this water solution of sodium silicate has several names - "verre soluble", water-glass, soluble glass, solution of water sodium silicate, soda water glass. About 25-27% is used in mining industry and in paper production
