Modified gypsum for the production of artificial stone and blocks
Modification of regular gypsum plaster into modified gypsum is compatible with all brands of semi-aqueous gypsum. Provides maximum efficiency in increasing the strength of gypsum binder by 2-4 times, increasing the softening rate, and reducing water consumption by 25% by weight of gypsum. The stabilizer additive promotes uniform strength gain and the development of crystals of a certain size without the formation of microcracks.
To slow down the setting time of the gypsum solution, only acids should be used: tartaric and citric. When using alcohol-based pigments, the setting time is accelerated.
The binder, plaster - is widely used for decorative and sculptural works in construction.
Today, with gypsum-based grade-16 of 16 MPa, modified to Modified gypsum with pigments, it is possible to obtain a nice look of marble –
- Density is 1700 - 2400kg /m ³
- Frost over 100 cycles
- Strength 25 –60 MPa and more.
- Water absorption 5-8%
- Density is 1700 - 2400kg /m ³
- The material after drying, is easy to grind and polish.
