Sustainable construction materials
Renca deliver all-in-one solution:
1. The complete system for geopolymer cement production
2. 3D printers and automatic mixing system for concrete
3. Technology for production a wide range of sustainable products based on local raw materials

Product range
Fire protection
Geopolymer concrete and products on its base are fire-resistant up to 1200°C depending on the used aggregates.
Sprayed geopolymer fire-resistant foam
Passed the Fire-resistance test at 1000°C for 2 hours in compliance to REI 120 Italian standard for fire protection
Acid, sulphates, salts resistant products
Geopolymer concrete is perfect material for sea-shore structures and structures exposed to aggressive substances. It is also mold resistant.
Sewer pipes, water pipes
Geopolymer foam can be used for retrofitting old sewer pipes and produce water pipes.
Low temperature geopolymer bricks
It is possible to make a construction bricks out of geopolymer concrete with the same properties as normal bricks, but without high-temperature burning, only at 40-70°C
Thermal insulation
Geopolymer foam is excellent thermal insulation material, which can be used both in hot and cold climates.
Water protection
Due to special nano-structure geopolymer is water resistant and could be used for foundations of the buildings with no additional protection.
Our Team
Our joint Italian-Russian company was founded in the beginning of 2016.
It is engaged in research, development and production of a wide range of sustainable materials for construction based on geopolymer technology as well as architectural concrete elements production and 3D printing.
Though the company is relatively young we have more than 10 years experience of work in the field.

Alex is CTO and co-founder of Renca. He is the data-base and creator of the breakthrough products that we have. He is a geologist-mineralogist by education and devotion and has more than 15 years experience in developing products that are used in almost every house today. He can create working recipes simply by looking at the test results of the materials at his disposal. Laboratory is his second home.

Mobile Automatic Mixing System for
geopolymer concrete

RENCA designed mobile automatic mixing system for geopolymer concrete compatible with any construction 3D printer. It also could be used for geopolymer concrete mixing for other applications.
