Silica nanoparticles hydrosol for concrete strength increase by adding to mixing water
Abstract
The article presents the results of tests of cement mortars prepared on activated (by an acoustic field frequency 22 kHz, power 4.0 W•cm -2 and electrochemical treatment voltage 15 V, current density 4.5 mA•cm -2 , steel electrodes) mixing water modified with silicon dioxide nanoparticles in the form of 3 %, 6 % and 10 % hydrosol.The construction of modern nuclear power facilities, solar energy panels base and other seismically resistant structures were required using of modified building materials that have high strength and protection levels.Currently, in the global construction industry, the main focus is on nano-additives that contribute to a significant increase in these indicators.Using the described technology allowed us to increase the strength of concrete by one grade.
