When nanocements is the best solution
Complicated logistical schemes in the region: utilization of local raw materials (including off-grade ones), damped wastes of TPPs, slag, sludge
High costs of cements and raw materials in the region
Tough construction schedule
High water and freezing resistance of projected cements
High compressive and flexural strength of projected concretes
Projected large-span structures
Utilization of architectural concretes used as structural ones
Drastic economy under new characteristics
Concrete produced on the basis of nanocements allows reduction of cement consumption, which is used in construction of:
High-rise buildings and blocks
In supporting columns – by 2–3 times
In slabs – by 1,3–1,5 times
Speed up the turnover of formworks – from 2 to 3 times
Reduce overall costs of carcasses of the buildings – from 20 to 40%
Hydro-engineering facilities
Enhance durability – by 2-3 times
Reduce consumption of cement – up to 2 times
Reduce costs of construction – from 30 to 50%
Tunnels
Reduce cement consumption – by 1,5 times
Enhance durability due to waterproof characteristics of concrete – by 2 times
Reduce overall costs – by 20–30%
Bridges and roads
Reduce cement consumption – by 1,5 times
Enhance durability – up to 2 times
Reduce costs – from 15 to 25%
Defense facilities
Increase strength of the buildings – from 2 to 2,5 times
Increase sustainability and durability – from 3 to 5 times
Nanocements can dramatically improve the quality and durability of concrete products. In particular, nanocements secure production of the following brands of high quality concretes with great deal of cement saving and exception of traditional steaming of products, while reducing power consumption and heat: High-strength and durable concretes for earthquake-resistance engineering, construction of high-rise buildings from tube-confined concrete and monolith; high-performance concretes for special structures, civil engineering and architectural complexes (thin membranes, supporting columns, beams, tubing, concrete frames and bridge structures); High-performance concretes for road construction (construction of roads, railways, airports, overpass structures, platforms, side stone, fencing, etc.); concretes for hydraulic structures, including marine, drilling rigs of oil extraction, underground tunnels and similar structures; architectural concrete (cast artificial stone) and products based on it for the improvement of cities: fountains, vases, anaglyphs, sculptures, etc.); High-quality cost-effective dry construction mixtures for multiple purposes (plastering, masonry, self-leveling floors, tile, etc.).
