Principal competitive advantages of nanocements

Figure 3. Technological diagramm of low clinker nano cement production

Feeding up to 70% of mineral additives with increase in cement production while maintaining its high grades without building new burning units

Utilization of local non-metallic aggregates (sub-standard sand, gravel, natural rocks, slag, ash) in production of super strong concretes

Usage of semi-finished (clinker) and sub-standard cements (stale, clotted, other)

Regulation of cement properties as per design task (desired strength, setting time, water resistance, plasticity, color, other)

Production of concretes of high and super high strength (higher than B60 class) with high water resistance (W12–W20) and resistance to sulfates, chlorides and soft acids

Economy of 30–50% of steel (reinforcement) in strong and super strong concretes

Speeding up of materials hardening, which reach 60–70 МPа of strength within 24 hours , and within 72 hours – acquire strength no lower than 70% of branded strength of concrete, aged 28 days.

Reduction (by 2–4 times) of cement consumption under the production of binding substance branded as 300–500 due to joint mechano-activation of silica additives (fined-grained sand, ash, slags)

Reduction of energy and resources consumption in production of concrete products by excluding steaming practiced for their quicker hardening

Production of architect concrete of enhanced ornamentality (pure tone, bright color) resistant to salt efflorescence on the surface of a product, which could be the result of exploitation in contaminated conditions of megapolises

Manufacture of products made of architect concrete with characteristics close to natural granite but cheaper by 3-5 times with the possibility of grinding and polishing
