Methods for predicting strength properties of cementless ash – slag concrete for a long time period have been developed at the Siberian State University of Industry. Data from a 10 – year study of an ordinary heavy concrete as compared with a cement concrete containing ash from thermal power plants were taken for analogies. The methods were as follows:
predicting based on the dynamics of the analog of the object for prediction using the method of similarity,
predicting based on the dynamics of the object indices in the “accelerated” time scale.
The first method included monitoring the dynamics of indices of the analogs of the object for prediction, monitoring the dynamics at the initial (limited) time period of the object functioning, determining coefficients of similarity, and predicting the object indices by affinal transformations and recalculations according to the similarity criteria. The second method consisted in obtaining the dynamics of the indices of the object analog functioning in the “accelerated” time scale, that is exposed to contrast loadings much more frequently than during the normal object functioning.
