EFFECT OF AGING OF THE BINDER ON THE CREEP OF POLYMER CONCRETE

polyester concretes with diabase and marble fillers and aggregates are used as examples to illustrate the possibility of using a structural approach to evaluate the creep of the composite in the initial state a nd after preliminary aging under laboratory conditions for a period of 12-13 yrs. Experimental study of the creep of polymer concrete and it s structural components (resin and binder) after preliminary aging at elevated temperatures (60, 90 degrees) established that the change tha t occurs in viscoelastic compliance with aging conforms to the analogy principle with a reduction function that depends on aging temperature and time.
