METHOD OF DETERMINING APPARENT ACTIVATION ENERGY OF HYDRATION PROCESSES IN FINE-GRAINED CEMENT CONCRETES IN INITIAL PERIOD OF HARDENING Russian patent published in 2024 - IPC G01N33/38 G01N3/08 G01N25/02 

FIELD: measuring.

SUBSTANCE: use for determination of apparent activation energy of hydration processes in fine-grained cement concretes in the initial period of hardening. Essence of the invention is that in order to determine the apparent activation energy of hydration processes in fine-grained cement concrete in the initial hardening period according to the strength of the samples held at different temperatures, plotting the graph of the natural logarithm of the strength gain constant on the inverse value of the thermodynamic temperature and determining the apparent activation energy value, wherein the degree of hydration of the binder is determined by the ratio of strength at the initial moment of time t to the strength of the samples held at room temperature for 28 days, from which the strength gain constant is then determined using the degree of hydration of the binder.

EFFECT: enabling determination of apparent activation energy of binder in fine-grained multicomponent concrete.
