High strength concrete with carbon nanotubes

Popis výsledku v původním jazyce

High strength concrete with strengths exceeding 80 MPa can only be manufactured with fine grained active additions. Amorphous microsilica is the most frequently used one; its specific surface is over 25 000 m2/kg and average size of grain between 0,5 and1. This addition has been used for manufacture of high strength concrete for at least 30 years. However, ultra fine active particles with average size around 10-50 nm are more effective, like nanosilica with at least 90 % of amorphous SiO2. Carbon nanotubes with diameter 2-5 nm also seem to be very promising for high strength and high performance concrete. The advantage of carbon nanotubes is low dosing and high effectivity increasing not only compressive strength and tensile bending strength but alsodurability of concrete exposed to cyclical freezing. Positive effect on reduction of carbonataion and increased resistance to chemically aggressive environments were also observed. The paper presents possibilities of use of carbon nanotub
