Study of the thermophysical kinetics of additional concrete samples

Abstract

In this work, Fix 1211 addition has been used in different amount in the iron mix. The samples prepared have been used thermically in the temperature 77[Formula: see text]C in normal atmosphere condition. The samples thermically developed have been thermically analyzed with the constant 5[Formula: see text]C/min of 20 ml/min argon gas from 30[Formula: see text]C up to 900[Formula: see text]C. Thermo-physical mechanisms have been researched in the cement, sand and road metal with the thermogravimetric (TG) and Differential Scanning Calorimetry (DSC) analysis. Mass kinetics, activation energy and special heat capacity have been researched for different temperature intervals. The decomposition mechanism of the mass in stages and the speed of decomposition is equal to the cost of the heat flow. The mass loss has been determined in 6.99 mg under the first code, 5.82 mg under the second code, 5.63 mg under the third code, 4.65 mg under the fourth code in [Formula: see text]C temperature interval. In addition, it has been researched that the activation energy has been changed between 0.56–0.80 eV and 0.23–0.36 eV under each code and phase passage.
