The product differences from analogues
The foamed glass shells are the nearest analogue of the proposed product.
The proposed production has the following differences from the known foamed glass shells:
- Material accurately specified size directly in the furnace manufacture is possible that eliminates the sawing of finished products and leads for the smooth outside and inside surfaces
- Increased strength of the material allows its using as self-supporting
- The resulted product manufacture of exactly sizes
The proposed technology differences of from analogues
- Various types of raw materials such as glass cullet (including off-grade) and natural silicate (diatomite, tripoli, flask, zeolites) are possible
- The minimum of metal forms absence during heat treatment significantly reduces the energy intensity and excludes the defect product
- Available and maintainable equipment is applied
- High cost and hard-to-reach components are absence in raw materials
- Absence of sawing and corresponding absence of huge volumes of material scrap
- The relatively low cost of the products obtained in the range from 100 up to 160 €/m3 (it depends on raw materials type, manufacture productivity and type of products)
- The author's experience in installation and starting the manufacture of similar materials in combination with one of the highest h-index among the experts in this field
Applications
The material was tested in building constructions in extreme climate conditions of Northern Russia
