Conclusions
-
1.
Ammonia water retards heat liberation of concrete and the more intensely, the higher the concentration.
-
2.
Retardation of heat liberation of concrete propared with ammonia water is considerably more effective compared to the addition of SNV.
-
3.
Regardless of the ammonia concentration in the mixing water, on reaching the same rise of temperature in an adiabatic regime the compressive strength, axial tensile strength, and modulus of elasticity of the concrete have practically the same values and only the time of reaching the specified rise of temperature varies.
